FAQS ABOUT AFFORDABLE CARE ACT 
IMPLEMENTATION PART 47 
July 19, 2021 
Set out below are Frequently Asked Questions (FAQs) regarding implementation of the 
Affordable Care Act. These FAQs have been prepared jointly by the Departments of Labor, 
Health and Human Services (HHS), and the Treasury (collectively, the Departments). Like 
previously issued FAQs (available at https://www.dol.gov/agencies/ebsa/about-ebsa/our-
activities/resource-center/faqs and http://www.cms.gov/cciio/resources/fact-sheets-and-
faqs/index.html), these FAQs answer questions from stakeholders to help people understand the 
law and benefit from it, as intended.  Clinical stakeholders should follow the HIV Preexposure 
Prophylaxis (PrEP) Clinical Practice Guideline and Providers Supplement: Update 2021. 
Coverage of Preventive Services 
Public Health Service Act (PHS Act) section 2713 and its implementing regulations1 
non-grandfathered group health plans and health insurance issuers offering non-grandfathered 
group or individual health insurance coverage (referred to in this document as plans and issuers) 
to provide benefits for, and prohibit the imposition of cost-sharing requirements with respect to, 
the following: 
  Evidence-based items or services that have in effect a rating of A or B in the current 
recommendations of the United States Preventive Services Task Force (USPSTF) with 
respect to the individual involved, except for the recommendations of the USPSTF 
regarding breast cancer screening, mammography, and prevention issued in or around 
November 2009, which are not considered in effect for this purpose;2 
  Immunizations for routine use in children, adolescents, and adults that have in effect a 
recommendation from the Advisory Committee on Immunization Practices (ACIP) of the 
Centers for Disease Control and Prevention (CDC) with respect to the individual 
involved;3 
1 26 CFR 54.9815-2713; 29 CFR 2590.715-2713; 45 CFR 147.130. 
2 The USPSTF published updated breast cancer screening recommendations in January 2016. However, section 223 
of Division H of the Consolidated Appropriations Act, 2021 (Pub. L. 116-260) requires that for purposes of PHS Act 
section 2713, USPSTF recommendations relating to breast cancer screening, mammography, and prevention issued 
before 2009 remain in effect until January 1, 2023.  
3 In addition, under section 3203 of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) and its 
implementing regulations, plans and issuers must cover, without cost-sharing requirements, any qualifying 
coronavirus preventive services pursuant to section 2713(a) of the PHS Act and its implementing regulations (or any 
successor regulations). The term qualifying coronavirus preventive service means an item, service, or 
immunization that is intended to prevent or mitigate coronavirus disasese 2019 (COVID-19) and that is, with respect 
to the individual involved (1) an evidence-based item or service that has in effect a rating of A or B in the 
current USPSTF recommendations; or (2) an immunization that has in effect a recommendation from ACIP 
(regardless of whether the immunization is recommended for routine use). 85 FR 71142 (Nov. 6, 2020).    With respect to infants, children, and adolescents, evidence-informed preventive care and 
screenings provided for in the comprehensive guidelines supported by the Health 
Resources and Services Administration (HRSA); and 
  With respect to women, preventive care and screening provided for in comprehensive 
guidelines supported by HRSA, to the extent not already included in certain 
recommendations of the USPSTF.4 
If a recommendation or guideline does not specify the frequency, method, treatment, or setting 
for the provision of a recommended preventive service, the plan or issuer may use reasonable 
medical management techniques to determine any coverage limitations.5 However, the 
4F
Departments have clarified in previous guidance that plans and issuers must accommodate any 
individual for whom a particular medication (generic or brand name) would be medically 
inappropriate, as determined by the individuals health care provider, by having a mechanism for 
waiving the otherwise applicable cost sharing for the brand or non-preferred brand version. If 
utilizing reasonable medical management techniques, plans and issuers must have an easily 
accessible, transparent, and sufficiently expedient exceptions process that is not unduly 
burdensome.6
The clarifying guidance in Q1-Q3 explains how the Departments expect plans and issuers subject 
to section 2713 of the PHS Act to cover without cost sharing the recommended preventive 
services under the requirements of the applicable implementing regulations. In consideration of 
the possibility that plans and issuers may not have understood that the regulatory coverage 
requirements apply to all support services of the USPSTFs recommendation for pre-exposure 
prophylaxis (PrEP), the Departments will not take enforcement action against a plan or issuer for 
failing to provide coverage of such services through the period ending 60 days after publication 
of these FAQs, and encourage states to take a similar enforcement approach.  
                                                           
4 For accommodations and religious and moral exemptions with respect to coverage of certain recommended 
contraceptive services, see 26 CFR 54.9815-2713A; 29 CFR 2590.715-2713A; 45 CFR 147.131 through 147.133. 
5 26 CFR 54.9815-2713(a)(4); 29 CFR 2590.715-2713(a)(4); 45 CFR 147.130(a)(4).

addition, the Departments have previously clarified that plans and issuers must cover, without cost sharing, items 
and services that are integral to the furnishing of the recommended preventive service, regardless of whether the 
item or service is billed separately. For example, the Departments clarified in subregulatory guidance that a plan or 
issuer may not impose cost sharing for polyp removal during a preventive screening colonoscopy, as the service is 
an integral part of a colonoscopy, and also stated that anesthesia provided in connection with a preventive 
colonoscopy must be covered without cost sharing if the attending provider determines that anesthesia would be 
medically appropriate for the individual. Similarly, several of the recommended preventive services involve 
screenings for the presence of certain health conditions, such as diabetes, or a variety of sexually transmitted 
infections. These recommended screenings, typically performed by laboratories, cannot be conducted without first 
collecting a specimen. Accordingly, the Departments have stated that plans and issuers must cover without cost 
sharing both the specimen collection and the recommended preventive service, regardless of how the specimen 
collection is billed. 85 FR 71142, 71174 (Nov. 6, 2020).  Coverage of Pre-Exposure Prophylaxis 
On June 11, 2019, the USPSTF released a recommendation with an A rating that clinicians 
offer PrEP with effective antiretroviral therapy to persons who are at high risk of human 
immunodeficiency virus (HIV) acquisition. Accordingly, plans and issuers must cover PrEP 
consistent with the USPSTF recommendation without cost sharing for plan years (in the 
individual market, policy years) beginning on or after one year from the issue date of the 
recommendation (in this case, plan or policy years beginning on or after June 30, 2020).7
Q1. Are plans and issuers required to provide coverage without cost sharing for items or 
services that the USPSTF recommends should be received by a participant, beneficiary, or 
enrollee prior to being prescribed anti-retroviral medication as part of the determination of 
whether such medication is appropriate for the individual and for ongoing follow-up and 
monitoring? 
Yes. As described in the USPSTF Final Recommendation Statement, the purpose of the 
recommendation is to decrease the risk of HIV transmission for persons who are at high risk of 
HIV infection.8 The USPSTF also notes that the CDC provides a complete discussion of 
implementation considerations for PrEP, including baseline and follow-up testing and 
monitoring, time to achieving protection, and discontinuing PrEP. The USPSTF 
recommendation cites CDC guidelines,9 which advise that PrEP is a comprehensive intervention 
comprised of antiretroviral medication and essential support services (including medication self-
management/adherence counseling, risk reduction strategies, and mental health counseling, etc.) 
that ensure PrEP is administered safely and effectively to persons who need it. Consistent with 
the CDCs advice, the USPSTF recommendation for PrEP includes a combination of baseline 
and monitoring services (described below), which are essential to the efficacy of PrEP. These 
services include certain clinical assessments necessary to ensure the medication prescribed for 
PrEP is given to  at-risk persons who are not infected with HIV and who have no medical 
contraindications, and to monitor patients taking the medication to ensure its safe, ongoing use.  
To this end, the USPSTF Final Recommendation Statement, in the Other Considerations, 
Implementation section, provides in relevant part: 
Before prescribing PrEP, clinicians should exclude persons with acute or chronic HIV 
infection through taking a medical history and HIV testing. The 2-drug antiretroviral 
regimen used in PrEP, when used alone, is not an effective treatment for HIV infection, 
and its use in persons living with HIV can lead to the emergence of, or selection for, 
                                                           
7 26 CFR 54.9815-2713(b); 29 CFR 2590.715-2713(b); 45 CFR 147.130(b). Generally, for purposes of section 2713 
of the PHS Act, USPSTF recommendations are considered to be issued on the last day of the month in which the 
USPSTF publishes or otherwise releases the recommendation. 75 FR 41726, 41729 (July 19, 2010).

https://www.cdc.gov/hiv/pdf/risk/prep/cdc-hiv-prep-guidelines-2017.pdf and 
https://www.cdc.gov/hiv/pdf/risk/prep/cdc-hiv-prep-provider-supplement-2017.pdf.  Additional CDC resources on 
PrEP for both clinicians and consumers are available at https://www.cdc.gov/hiv/risk/prep/index.html, such as HIV

testing, serologic testing for hepatitis B and C virus, testing for other [sexually 
transmitted infections (STI)], and pregnancy testing (when appropriate) be conducted at 
the time of or just before initiating PrEP. Ongoing follow-up and monitoring, including 
HIV testing every 3 months, is also suggested ... Reduced adherence is associated with 
marked declines in effectiveness. Therefore, adherence support is a key component of 
providing PrEP.  Components of adherence support include establishing trust and open 
communication with patients, patient education, reminder systems for taking medication, 
and attention to medication adverse effects and having a plan to address them.  
The USPSTF Final Recommendation Statement encompasses FDA-approved PrEP antiretroviral 
medications, as well as the following baseline and monitoring services:  
1.  HIV testing: Persons must be tested and confirmed to be HIV uninfected before starting 
PrEP and tested again for HIV every three months while taking PrEP so that, if they have 
become infected, the medication can be stopped promptly before it could cause a harmful 
drug resistance to develop. 
2.  Hepatitis B and C testing: Persons should be screened for hepatitis B virus (HBV) at 
baseline for the initiation of PrEP consistent with CDC guidelines, so that when the PrEP 
medications, which suppress HBV replication in the liver, are stopped, persons can be 
monitored to ensure safety and to rapidly identify any potential injury. Additionally, 
persons should be screened for hepatitis C virus (HCV) infection at baseline and 
periodically consistent with CDC guidelines.  Screening for HCV infection is indicated 
for all people with ongoing risk of contracting HCV. 
3.  Creatinine testing and calculated estimated creatine clearance (eCrCl) or glomerular 
filtration rate (eGFR): For persons taking PrEP, their estimated eCrCl or eGFR must be 
measured and calculated at the beginning of treatment to assess if kidney function is in 
the range for safe prescribing of PrEP medication. Creatinine and eCrCL or eGFR should 
be checked periodically consistent with CDC guidelines while on PrEP medication to 
assess for potential kidney injury and to ensure that it is safe to continue PrEP 
medication. 
4.  Pregnancy testing: Persons with childbearing potential taking PrEP must be tested for 
pregnancy at baseline and should be tested again periodically thereafter consistent with 
CDC guidelines until PrEP is stopped so that pregnant patients, together with their health 
care providers, can make a fully informed and individualized decision about taking PrEP.  
5.  Sexually transmitted infection (STI) screening and counseling: Persons taking PrEP must 
be screened for STIs at baseline and should be screened periodically thereafter consistent 
with CDC guidelines, which may require multiple anatomic site testing (i.e., genital, 
oropharyngeal, and rectal) for gonorrhea and chlamydia, and testing for syphilis, together 
with behavioral counseling, which are recommended to reduce the risk of STIs, the 
presence of which may increase the likelihood of acquiring HIV sexually. 
6.  Adherence counseling: Persons taking PrEP must be offered regular counseling for 
assessment of behavior and adherence consistent with CDC guidelines to ensure that 
PrEP is used as prescribed and to maximize PrEPs effectiveness.  Plans and issuers are also required to cover without cost sharing office visits associated with 
each recommended preventive service applicable to the participant, beneficiary, or enrollee when 
the service is not billed separately (or is not tracked as individual encounter data separately) from 
an office visit, and the primary purpose of the office visit is the delivery of the recommended 
preventive service.10 
Q2: May a plan or issuer use reasonable medical management techniques to restrict the 
frequency of benefits for services specified in the USPSTF recommendation for PrEP, such 
as HIV and STI screening, in a manner specified under other existing USPSTF 
recommendations, or otherwise?  
No. The USPSTF PrEP recommendation specifies the frequency of certain services for 
individuals specified in the recommendation.  Plans and issuers may use reasonable medical 
management techniques to determine the frequency, method, treatment, or setting for the 
provision of a recommended preventive service only to the extent not specified in the applicable 
recommendation or guideline.  
In addition, when PrEP is medically appropriate for an individual specified in the USPSTF 
recommendation, as determined by the individuals health care provider, it would not be 
reasonable to restrict the number of times the individual may start PrEP. 
Q3: When may a plan or issuer use reasonable medical management techniques with 
respect to coverage of PrEP? 
Consistent with PHS Act section 2713 and its implementing regulations, plans and issuers may 
use reasonable medical management techniques to encourage individuals prescribed PrEP to use 
specific items and services, to the extent the frequency, method, treatment, or setting is not 
specified in the USPSTF recommendation. For example, since the branded version of PrEP is not 
specified in the USPSTF recommendation, plans and issuers may cover a generic version of 
PrEP without cost sharing and impose cost sharing on an equivalent branded version.11 
However, plans and issuers must accommodate any individual for whom a particular PrEP 
medication (generic or brand name) would be medically inappropriate, as determined by the 
individuals health care provider, by having a mechanism for waiving the otherwise applicable 
cost sharing for the brand or non-preferred brand version.12  
If utilizing reasonable medical management techniques, plans and issuers must have an easily 
accessible, transparent, and sufficiently expedient exceptions process (for example, one that 
                                                           
10 26 CFR 54.9815-2713(a)(2); 29 CFR 2590.715-2713(a)(2); 45 CFR 147.130(a)(2). 
11 Currently, there are two medications approved for daily use as PrEP. Both are combinations of two anti-HIV 
drugs in a single pill: (1) Emtricitabine (F) 200 mg in combination with tenofovir disoproxil fumarate (TDF) 300 mg 
(F-TDF; brand name Truvada) is recommended for all adults and adolescents at risk for HIV through sex or 
injection drug use; and (2) Emtricitabine (F) 200 mg in combination with tenofovir alafenamide (TAF) 25 mg (F-
TAF; brand name Descovy) is recommended for adults and adolescents at risk for HIV through sex, excluding 
people at risk through vaginal sex. 
12 To comply with essential health benefits requirements, non-grandfathered individual and small group market 
insurance plans must also have an exceptions process in place that complies with 45 CFR 156.122(c).  allows prescribing and accessing PrEP medications on the same day that a participant, 
beneficiary, or enrollee receives a negative HIV test or decides to start taking PrEP) that is not 
unduly burdensome on the individual or a provider (or other individual acting as an authorized 
representative), as set forth in the Departments previous guidance.13
