The Veterans' Health Care Eligibility Reform Act of 1996 required that VA establish an enrollment system to help manage its health care delivery system. VHA's HEC is the business owner of the Enrollment System-- the official system of record for verifying veterans' eligibility for health care benefits and maintaining enrollment information. To enroll for health care benefits, veterans submit an application to either HEC or a VAMC. Application information includes demographic, military service, financial, and insurance information. A veteran may apply online, by mail, by fax, by phone, or in person. Once a veteran submits an application, there are three key steps for processing the application: intake of application, verification of eligibility, and enrollment determination. There may be an additional processing step--resolving a pending application--if enrollment staff need additional information to determine eligibility. According to VHA policy, staff are required to process applications within 5 business days of receipt. Figure 1 provides an overview of the enrollment process, as of June 2017. Intake of application. If a veteran applies in person, or faxes or mails an application to a VAMC, local enrollment staff enter the application information into the VAMC's Veterans Health Information Systems and Technology Architecture (VistA) system. If a veteran applies in person, by phone, or faxes or mails an application to HEC, HEC enrollment staff enter application information into the Enrollment System. A veteran may also apply online, and the application information is directly transmitted into the Enrollment System. Historically, VAMCs have received more than 90 percent of enrollment applications for processing. Verification of eligibility. After the intake of an application, VAMC and HEC staff attempt to verify whether veterans meet eligibility requirements based on their military service and, if applicable, financial information. VAMC staff attempt to verify military service by reviewing supporting documentation provided by veterans (e.g., military discharge or separation papers). If veterans do not provide any documentation of military service, staff will try to verify this information through military service databases. For application information that HEC staff have entered into the Enrollment System or for those applications that have been submitted online with information transmitted directly to the Enrollment System, the system assesses eligibility based on the information entered. Both VistA and the Enrollment System automatically assess whether a veteran's self-reported income meets VHA income thresholds for eligibility, as applicable. VAMC staff are required to ensure that application information is accurately entered into VistA. Application information that is entered into local VistA systems is transmitted nightly into the Enrollment System. Enrollment determination. The Enrollment System makes all enrollment determinations, including those for applications processed at VAMCs. Specifically, the Enrollment System determines whether veterans are enrolled, rejected, or ineligible for health care benefits. Veterans who are enrolled or rejected are placed in a category based on type of eligibility--called a priority group--established to manage the provision of care. For example, priority group 1 consists of veterans who are rated 50 percent or greater based on service-connected disabilities. Priority group 5 consists of veterans who are eligible because their incomes are at or below VHA's eligibility thresholds; and priority group 8g consists of non-service connected veterans whose incomes are above the thresholds, and thus are rejected for health care benefits. HEC sends a letter and a personalized handbook to each veteran once it has made an enrollment determination with the decision and a description of benefits, if applicable. Resolving pending applications. If VAMC or HEC enrollment staff cannot verify veterans' eligibility for making an enrollment determination, the application is categorized as pending. To resolve a pending application, VAMC or HEC staff are to contact the veteran to obtain the missing information (e.g., military service or financial information). VAMC and HEC staff share responsibility for resolving pending applications. For instance, HEC staff may send a pending application for VAMC staff to help process. VAMC staff may also contact HEC staff for assistance in collecting missing information because, for example, according to officials, HEC has greater access to military service databases. VHA enrollment staff, both from HEC and VAMCs, frequently did not process enrollment applications in accordance with VHA's timeliness standards and made incorrect enrollment determinations. VHA, through HEC, is assessing efforts to improve its enrollment processes. Prior studies show that VHA enrollment staff, whether from HEC or VAMCs, frequently did not process enrollment applications within 5 business days in accordance with VHA timeliness standards. Specifically, a June 2016 VHA audit found that HEC staff did not process 143 of 253 applications reviewed (57 percent) within VHA's timeliness standard. The audit found that this occurred, in part, because HEC enrollment staff were not prioritizing workload to focus on processing applications that were approaching the timeliness standard. In response to an audit recommendation, HEC officials said they have begun prioritizing workload to help meet the timeliness standard. A VHA Chief Business Office analysis showed that VAMCs also did not consistently process online applications within 5 business days. According to the analysis, only 35 percent of online applications were processed by VAMCs within 5 business days in fiscal year 2012 and 65 percent through the first 7 months of fiscal year 2016. VAMC officials we contacted said because there is no mechanism for veterans to provide supporting military service records, such as discharge papers, with their online applications, VAMC staff need to obtain the information by querying available military service databases or following up with the veterans, which may cause delays in processing. Several VAMC officials said that HEC should implement automated controls that do not allow veterans to submit online applications without attaching supporting documents that include information needed for making enrollment determinations. Additionally, the overall time needed to process enrollment applications may increase when staff need to place applications in a pending status. In its September 2015 report, VA's Office of Inspector General found that, as of September 2014, the Enrollment System contained nearly 870,000 pending applications, many of which had been pending for more than 5 years. According to the report, 72 percent of those applications were pending because additional financial information was needed from veterans. In response to the report, in 2016, HEC and VAMCs undertook outreach efforts, such as attempting to contact all veterans with pending applications via phone and letters. According to HEC officials, as of May 2017, they were able to resolve about 30 percent of the applications (about 255,000 applications). This included enrolling approximately 88,000 veterans, as well as removing from pending status applications for which HEC officials said veterans were no longer living. HEC officials and VAMC staff in our review said they experienced problems resolving pending applications because they were generally several years old and lacked accurate contact information. HEC officials stated they would continue to work on resolving them, but if staff cannot obtain the information within 365 days, the applications' status will change from pending to closed at that time. Based on our discussions with enrollment staff, we found that none of the VAMCs in our review had a specific policy or procedure for how to resolve pending applications. Officials indicated that they had not received any national procedure or guidance from VHA, nor had they developed local procedures. According to federal internal control standards, management should design control activities, such as policies and procedures, to achieve objectives and respond to risk. In the absence of a standard procedure for VAMCs to use to resolve pending applications, veterans are at risk for experiencing unnecessary delays while waiting for their applications to be processed. For the six VAMCs in our review, we found that, as of March and April 2017, VAMC enrollment staff had not resolved 31 (55 percent) of the 56 pending applications included in our random, nongeneralizable sample of pending applications. (See table 1.) Specifically we found that for 22 (71 percent) of the 31 unresolved applications there was no evidence that VAMC enrollment staff had attempted to contact the veterans to obtain missing military service or financial information, and that 18 of these 22 applications had been in a pending status for 3 months or longer at the time of our review. VAMC officials told us they were not aware that some of the unresolved were in a pending status prior to our review. For the remaining 9 applications, we found VAMC enrollment staff attempted to contact the veterans, but were unable to resolve the application, for example, due to the lack of response from the veteran or lack of valid contact information. These 9 applications had been in a pending status between 2 and 5 months at the time of our review. For the 25 applications that enrollment staff resolved, we found that staff enrolled the veterans for 19, and for the other 6, staff determined the veterans were ineligible or rejected for enrollment. We also found the time it took staff to make an enrollment determination varied widely--ranging from 3 to 119 days. (See table 2.) Officials from five of the six VAMCs told us that based on our review they recognized the need to improve their processes. For example, officials from two VAMCs indicated that they were going to develop a standard operating procedure for identifying pending applications, following up with veterans to obtain missing information, and documenting actions such as the dates that enrollment staff called veterans or mailed letters to resolve outstanding issues. VHA's Compliance and Internal Control Program Office conducted two audits (in April and August 2016), which found that VHA enrollment staff, including those from HEC and VAMCs, frequently made incorrect enrollment determinations. In some cases, veterans were rejected for health care benefits when those veterans should have been enrolled, and in other cases veterans were enrolled when they were ineligible for benefits, according to these audits. Specifically, VHA's audits found the following: HEC had a 12 percent error rate. The April 2016 audit found that HEC enrollment staff made incorrect determinations for 31 of 253 randomly selected applications. The audit found that these errors included a combination of incorrect enrollment and rejection determinations, and the most frequent errors--in 15 of the 31 cases--related to enrollment staff enrolling or rejecting veterans for health care benefits without sufficient documentation, such as proof of military service. Audit findings indicated these applications should have been assigned a pending status. VAMCs had a 27 percent error rate. The August 2016 audit found that VAMC enrollment staff made incorrect determinations for 101 of 381 randomly selected applications. Similar to the audit of HEC, the audit of VAMCs found that errors included a combination of incorrect enrollment and rejection determinations. For example, the audit of VAMCs identified 15 applications for which enrollment staff incorrectly rejected the veterans for health care benefits. According to the audit, VAMC staff should have either enrolled the veterans because they had provided adequate documentation needed to verify their eligibility, or categorized the applications as pending until adequate documentation was obtained such as proof of military service needed to verify eligibility. In addition to the two audits, VHA's Compliance and Internal Control Program Office conducted an informal review that found for a sample of 357 phone applications, enrollment staff made incorrect enrollment determinations for 87 (24 percent ). The most frequent errors again related to staff enrolling or rejecting veterans for health care benefits without sufficient documentation, such as proof of military service. In these instances, the applications should have been assigned a pending status, according to the review. Although documentation on the audits and the informal review did not provide information on specific causes of the errors, officials responsible for conducting the audits indicated that the incorrect enrollment determinations were the result of human error. Through its HEC, VHA is assessing efforts to improve the timeliness of enrollment application processing and the accuracy of enrollment determinations. Specifically, HEC officials established the National Enrollment Improvement, an initiative which includes two efforts to centralize or standardize key aspects of enrollment processes. One effort involves VAMCs' processing of applications using the Enrollment System rather than VistA. To examine potential options, HEC implemented two pilots in 2016: Pilot 1-- implemented May through August 2016, required enrollment staff at three VAMCs to process all applications by entering information directly into the Enrollment System. VAMC enrollment staff participating in this pilot told us they encountered challenges, including not being able to log into the Enrollment System, and frequently had to revert to processing many applications in VistA. In total, the VAMCs processed 239 applications using the Enrollment System, which did not provide HEC sufficient data for determining the pilot's effectiveness, according to the officials responsible for implementing the pilot. Pilot 2--a case study implemented over 2 weeks in December 2016, required enrollment staff at six VAMCs to enter application information for veterans applying in person into an online application for direct transmittal to the Enrollment System. According to officials, a goal of the pilot was to test the automatic verification of military service information against databases to reduce human intervention in verifying eligibility, thereby improving the timeliness and accuracy of enrollment determinations. Similar to the first pilot, technology issues precluded effective processing. For example, automated verification was not consistently successful, and most applications processed (65 of 86) required manual intervention to reach an enrollment determination. In addition, officials said the online application did not always capture information needed to make an enrollment determination. HEC officials told us they did not obtain sufficient information from the pilots to make a decision on which option would replace VAMCs use of VistA for processing applications. As such, HEC officials told us they are planning to conduct a third pilot to further test the option of having VAMCs enter application information directly into the Enrollment System. Officials said they do not have a definitive implementation plan or timeline for conducting this pilot. A second effort under the National Enrollment Improvement involves standardizing the process of resolving pending applications. HEC developed procedures for HEC enrollment staff to use when resolving pending applications. Specifically, when a veteran's application is placed in a pending status, staff are to send the veteran a letter that includes information about why the application is pending; the information HEC needs to make an enrollment determination; and instructions for providing the information to HEC. Additionally, staff are instructed to make phone calls at pre-determined time intervals--8 days, 30 days, 90 days, 180 days, and 310 days after an application becomes pending--in an attempt to contact the veteran to obtain missing information. HEC enrollment staff are also required to document each phone call attempt and the results. If staff are able to obtain the information within 1 year of informing a veteran about an application's pending status, that information is documented, and staff make an enrollment determination. If, after 365 days, staff cannot obtain the information needed to make an enrollment determination, the application status would be changed from pending to closed in the Enrollment System. Although HEC has developed standardized procedures for the resolution of pending applications by HEC staff, it has not communicated these procedures to VAMC enrollment staff. Officials from the six VAMCs in our review indicated they were not aware of HEC's plans to standardize this process, nor had they been asked to provide input or feedback on some of the challenges they have experienced. Furthermore, VAMC officials told us that they had not received any guidance regarding the new procedures and were confused about whether they would continue to have a role in this process. HEC's new procedures do not specify whether VAMCs have a continued role in resolving pending applications and whether the procedures apply to VAMCs, although HEC officials told us that VAMCs would continue to be involved. According to federal internal control standards for information and communication, management should internally communicate the necessary information to achieve the agency's objectives. Communicating quality information down and across reporting lines enables personnel to perform key roles in achieving objectives, addressing risks, and supporting the internal control system. In the absence of HEC coordination and communication with VAMCs about its effort to standardize the process for resolving pending applications, including the role VAMCs will have, there may be duplication of efforts between HEC and VAMC enrollment staff, which could lead to inefficiencies. VHA lacks a standardized process for system-wide oversight of enrollment processes to ensure applications are processed in a timely manner and enrollment determinations are accurate. Further, VHA, through HEC, lacks reliable data to oversee timely processing of applications across VAMCs. HEC has recently implemented an effort to review the accuracy of some enrollment determinations, specifically those for which veterans were found to be ineligible or rejected for health care benefits. VHA has not sufficiently defined through policies or procedures a standardized oversight process that describes and delineates the roles and responsibilities of HEC and VISNs--the networks that manage and oversee VAMCs in their geographic area--in monitoring and evaluating the efficiency and effectiveness of enrollment processes. Although HEC officials said they are responsible for oversight of enrollment processes system-wide and VHA policy generally states that HEC is responsible for performing a second-level review of all enrollment determinations, policies and procedures do not document the key oversight activities that should be conducted, how often they should be done, or the data that should be assessed for ensuring timely and accurate enrollment processes system-wide. Additionally, although HEC officials said VISNs should be overseeing VAMCs' enrollment processes within their networks, we found that VHA's policies do not describe these oversight role and responsibilities. Officials from the six VISNs in our review reported different perspectives about their role in overseeing enrollment processes, and as a result, oversight activities were limited and varied across these VISNs. For example, officials from two of the VISNs in our review considered VISNs to have no role in the oversight of enrollment processes, and primarily provided information from HEC to the VAMCs within their networks. In contrast, an official from another VISN did consider VISNs to have an oversight responsibility, and that VISN is planning to develop a standard set of report requirements for VAMCs within the network to use so that the VISN would have consistent information to use for monitoring VAMCs' enrollment processes. According to federal internal control standards for a control environment, an agency should establish an organizational structure and assign responsibility for achieving its objectives. An oversight structure would help fulfill responsibilities set forth by applicable laws and regulations, and relevant government guidance. Without defining a standardized process for oversight, HEC--VHA's entity responsible for enrollment--may be unable to determine what oversight, if any, is being conducted system- wide and may not have key information about deficiencies in processing enrollment applications. Thus, HEC is limited in its ability to effectively develop systematic solutions and ensure enrollment processes are efficient and resulting in accurate enrollment determinations. HEC officials said they recognized the need to improve the oversight of enrollment processes, and a goal under the National Enrollment Improvement is for HEC to have 100 percent accountability and oversight of applications-- those processed both at HEC and at the VAMCs. VHA--through HEC--does not have complete and reliable data for overseeing the timeliness of processing enrollment applications system- wide. HEC has data about processing timeliness for the applications that it receives. HEC officials said it lacks similar data for those applications received by the VAMCs--which comprised about 90 percent of the applications received system-wide in fiscal year 2016. HEC officials said they are able to monitor processing timeliness for the applications they receive because enrollment staff log the dates of the applications received into a workload tool and track monthly the processing timeliness and application status, such as the percent of applications that remained pending. In contrast, applications received by VAMCs are entered into local VistA systems that do not capture information on the date the application was received, which precludes accurate measurement of the timeliness of application processing. Although VistA captures the date enrollment staff entered the application information into the system, this date may not yield an accurate start date to measure timeliness of processing, specifically for applications received by mail or fax, because there is no assurance the information was entered when the application was received, according to HEC officials and VAMC staff. For example, officials from one VAMC in our review said if mailed or faxed applications are missing military service or financial information, staff do not enter the information into VistA until all the required information is obtained. Absent the information in VistA needed to track and monitor their performance in processing enrollment applications, three of the six VAMCs in our review developed Excel spreadsheets to collect this information. These spreadsheets tracked the dates when applications were received, as well as the enrollment determination made for each. However, such Excel spreadsheets were developed and maintained solely at the discretion of individual VAMCs in our review. HEC and VAMCs in our review also have varying interpretations of how to measure whether VHA's 5 business day timeliness standard has been met. VHA policy states the starting point for measuring adherence with its timeliness standard is the date the application was submitted online by the veteran, time-stamped when received by VAMCs or HEC, or the date the veteran came in person to apply. However, the policy does not define the end point for measuring the amount of time elapsed and does not specify whether the processing time includes the time applications are pending due to missing information. HEC officials told us the end point is the date of an enrollment determination, and measurement of timeliness should include any time the application was pending. Officials from four of the six VAMCs in our review, in contrast, said they considered the timeliness standard met when an application was entered into the system, irrespective of whether an enrollment determination was made or whether the application was pending. According to federal internal control standards for information and communication, management should use quality information to achieve the entity's objectives. Management obtains relevant data from relevant internal and external sources in a timely manner based on identified information requirements. Relevant data collected have a logical connection with identified information requirements, and management evaluates the sources of data for reliability. Without a central repository of reliable data about enrollment processes and a clearly defined measurement of the processing standard, VHA cannot reliably and consistently oversee processing timeliness of enrollment applications, assess the extent to which VAMCs face challenges in meeting the standard, and make appropriate decisions to improve processes system- wide. HEC officials acknowledged their lack of adequate information to monitor timeliness of application processing system-wide and told us they plan to develop the capacity to collect this information. Under the National Enrollment Improvement, HEC officials identified several steps for collecting standardized and centralized data for conducting oversight, including (1) eliminating VAMCs use of VistA for processing enrollment applications and solely using the Enrollment System, which is able to capture application receipt dates, (2) developing standardized procedures for capturing in the Enrollment System the date a mailed application was received, and (3) developing a series of reporting metrics for assessing the timeliness of processing applications across different modes. However, HEC officials told us that they need VHA approval to implement these actions, and as of June 2017, they did not have a timeline for when these actions might be implemented to allow them to accurately track and report on processing timeliness across all modes and VAMCs. HEC has efforts underway and planned to oversee the accuracy of enrollment determinations made system-wide. First, VHA--through HEC--has recently implemented an effort to review the accuracy of enrollment determinations for which veterans were found to be ineligible or rejected for health care benefits. This effort, which began in March 2017, employs a dedicated team of HEC staff to centrally conduct these secondary reviews daily, according to HEC officials. Prior to this date, VHA instructed VAMCs to conduct monthly secondary reviews of the accuracy of these enrollment determinations, and report the results of these reviews to HEC. However, HEC officials said they conducted an internal review of a sample of applications that had undergone this secondary review, and found that 20 to 30 percent still were incorrectly determined to be ineligible or rejected. Although HEC officials said VAMCs should continue these secondary reviews, HEC will also conduct its own independent review of all ineligible or rejected enrollment determinations. HEC officials said they plan to use the results of the reviews for quality assurance and training purposes with HEC and VAMC enrollment staff. Additionally, HEC officials told us they plan to expand their reviews of the accuracy of enrollment determinations and are currently assessing how to conduct second level reviews effectively system-wide. Although VHA policy states that HEC is responsible for performing a second-level review of all enrollment determinations, HEC officials said they have not been fully adhering with this requirement because, primarily, they have been focused on resolving the backlog of pending applications. Timely and accurate processing of veterans' enrollment applications is critical to ensuring that eligible veterans obtain needed health care. Without efficient and effective enrollment processes, veterans may be delayed in obtaining needed services or incorrectly denied benefits. VHA's current enrollment processes are decentralized and fragmented, with enrollment processing spread across 170 individual VAMCs as well as VHA's HEC. The current processes are also prone to delays and errors, such as enrollment staff frequently not meeting the 5-day timeliness standard and making incorrect enrollment determinations when processing veterans' enrollment applications. In particular, in some instances veterans may not have provided all the information HEC or VAMC staff need to process an enrollment application and the application becomes pending. VAMCs, however, do not have effective processes for obtaining information needed to resolve pending applications, which has resulted in veterans experiencing unnecessary delays waiting for enrollment determinations. Although HEC has developed new procedures for its staff to resolve pending applications, the procedures do not delineate whether VAMCs have a continued role in this process or whether they should be following these new procedures. A system-wide standard procedure that clarifies the roles and responsibilities of VAMC enrollment staff in resolving pending applications may help improve efficiency and help ensure that veterans receive a timely response when applying for health care benefits. Additionally, limitations in VHA's oversight further impede its ability to ensure the timeliness of application processing and the accuracy of enrollment determinations system-wide. VHA has not sufficiently defined roles and responsibilities for HEC and VISNs for conducting oversight of enrollment processing. Without establishing and clearly communicating the entity responsible for oversight and the activities that should be routinely conducted, there are no assurances that oversight is being conducted system-wide and deficiencies are being addressed appropriately. Oversight is further challenged by the lack of reliable and consistent data needed to evaluate timeliness of processing enrollment applications, and a clearly defined policy to measure processing timeliness. Due to this lack of data needed for system-wide oversight, VHA may be unable to determine if all veterans who submit an application to VAMCs--which handle a majority of the applications system-wide--are receiving timely enrollment determinations. HEC has efforts planned to improve its oversight; implementing and assessing these efforts may help ensure the timeliness and accuracy of enrollment processes, and help VHA make appropriate system-wide process improvements. We recommend that the Secretary of Veterans Affairs direct the Acting Under Secretary for Health to take the following four actions: 1. Develop and disseminate a system-wide standard operating procedure that clearly defines the roles and responsibilities of VAMCs in resolving pending enrollment applications. 2. Clearly define oversight roles and responsibilities for HEC, and for VISNs as appropriate, to help ensure timely processing of applications and accurate enrollment determinations. 3. Develop procedures for collecting consistent and reliable data system- wide to track and evaluate timeliness of enrollment processes, and institute an oversight mechanism to ensure VAMC and HEC enrollment staff are appropriately following the procedures. 4. Clarify its 5-day timeliness standard for processing enrollment applications, including whether it covers the total time needed to make an enrollment determination and the time applications are pending, and ensure the clarification is communicated system-wide. We provided VA with a draft of this report for its review and comment. VA provided written comments, which are reprinted in appendix I. In its written comments, VA concurred with all four of the report's recommendations, and identified actions it is taking to implement them. In addition, VA provided technical comments which we incorporated as appropriate.

Summary:
Enrollment is generally the first step veterans take to access VA health care, thus timely and accurate processing of enrollment applications is critical to help ensure eligible veterans obtain needed care. The Explanatory Statement accompanying the Consolidated Appropriations Act, 2016 included a provision for GAO to examine VA's oversight of patient access to care. This report examines (1) VHA's processes for enrolling veterans for health care benefits and (2) its related oversight. GAO reviewed federal laws, regulations, and VHA policies and procedures. GAO also interviewed officials from HEC and 6 of VHA's 170 VAMCs selected to provide variation in factors such as number of enrollment applications processed and geographic location; reviewed actions to resolve a randomly selected, nongeneralizable sample of pending enrollment applications from these 6 VAMCs; and interviewed HEC and VAMC officials on oversight of enrollment processes. The Department of Veterans Affairs' (VA) Veterans Health Administration's (VHA) implementation and oversight of enrollment processes need improvement to help ensure the timely enrollment of veterans for health care benefits. VHA frequently did not meet timeliness standards: VHA studies conducted in 2016 revealed that enrollment staff frequently did not process veterans' enrollment applications within the timeliness standard of 5 business days. These issues were found both at VHA's Health Eligibility Center (HEC)--the central enrollment processing center--and at local VA medical centers (VAMC) that also process enrollment applications. In response to an audit recommendation, HEC officials said they have begun prioritizing workload to help meet the timeliness standard. Additionally, the overall time needed to process enrollment applications may increase when staff need to place applications in a pending status, as pending applications require additional information, such as military service information, for staff to make enrollment determinations. However, none of the six VAMCs GAO reviewed had a specific policy for how to resolve pending applications. GAO found that VAMC enrollment staff had not resolved more than half of the pending applications GAO reviewed at these six VAMCs, some of which had been pending for more than 3 months at the time of the review. Although HEC developed new procedures for its enrollment staff to use when resolving pending applications, these procedures were not communicated to VAMCs. Officials from the VAMCs GAO reviewed said that they had not received guidance on these procedures and were confused about whether they would continue to have a role in this process. In the absence of HEC communication with VAMCs, there may be inefficiencies in resolving pending applications. VHA, through HEC, is assessing efforts to improve the timeliness of enrollment application processing and the accuracy of enrollment determinations. VHA lacks a standardized oversight process and reliable data to monitor enrollment processes system-wide: Although HEC officials said they are responsible for oversight of enrollment processes system-wide, VHA has neither sufficient policies that delineate this role nor procedures that document key oversight activities that should be conducted. For example, policies do not describe the oversight activities HEC should conduct to help ensure the accuracy of enrollment determinations system-wide. Further, VHA does not have reliable data for overseeing the timeliness of processing enrollment applications at VAMCs, which process 90 percent of the applications system-wide. Officials from the six VAMCs in GAO's review and HEC also had varying interpretations of how to measure the timeliness standard. For example, officials from four of the six VAMCs said the standard was met when enrollment staff entered an application into their local system, irrespective of whether an enrollment determination was made. In contrast, HEC officials said the measurement encompasses the time needed to make an enrollment determination, including any time the application was pending. Without reliable data that are consistently measured, VHA cannot accurately oversee the timeliness of application processing system-wide, or assess the extent to which VAMCs face challenges in implementing enrollment processes. To improve oversight, VHA, through HEC, recently implemented an effort to review the accuracy of some enrollment determinations. GAO recommends that VHA (1) define the responsibilities of VAMCs in resolving pending enrollment applications; (2) define oversight responsibilities to help ensure timely application processing and accurate enrollment determinations; (3) develop procedures for collecting reliable data system-wide to evaluate the timeliness of application processing; and (4) clarify its 5-day timeliness standard. VA concurred with all of GAO's recommendations and identified actions it is taking to implement them.
