CMS National Coverage PolicySocial Security Act (Title XVIII) Standard References:Title XVIII of the Social Security Act, Section 1833(e) states that no payment shall be made to any provider of services or other person under this part unless there has been furnished such information as may be necessary in order to determine the amounts due such provider or other person under this part for the period with respect to which the amounts are being paid or for any prior period.Article TextThis Billing and Coding Article provides billing and coding guidance for Local Coverage Determination (LCD) L33975, Psychiatric Inpatient Hospitalization. Please refer to the LCD for reasonable and necessary requirements.Coding GuidanceNotice:It is not appropriate to bill Medicare for services that are not covered (as described by the entire LCD) as if they are covered. When billing for non-covered services, use the appropriate modifier.Documentation RequirementsAll documentation must be maintained in the patient's medical record and made available to the contractor upon request.Every page of the record must be legible and include appropriate patient identification information (e.g., complete name, dates of service[s]). The documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care to the patient.The submitted medical record must support the use of the selected ICD-10-CM code(s). The submitted CPT/HCPCS code must describe the service performed.The initial psychiatric evaluation with medical history and physical examination should be performed within 24 hours of admission in order to establish medical necessity for psychiatric inpatient hospitalization services. The documentation should include:Patients chief complaint or description of acute illness or exacerbation of chronic illness requiring admission;Current and past psychiatric history (if available), including evidence of failure at or inability to benefit from a less intensive, outpatient program; prior level of function; history of substance abuse; and any suicidal ideations.Current and past medical history (if available);Family, vocational and social history (if available);Mental status examination, including general appearance and behavior, orientation, affect, motor activity, thought content, long and short term memory, estimate of intelligence, capacity for self harm and harm to others, insight, judgment, capacity for activities of daily living (ADLs);Physical examination;Formulation of the patients status, including an assessment of the reasonable expectation that the patient will make timely and significant practical improvement in the presenting acute symptoms as a result of the psychiatric inpatient hospitalization services; andICD-10-CM/DSM-IV-TRTMdiagnoses, including all five axes of the multiaxial assessment as described in the DSM-IV-TRTM.A team approach may be used in developing the initial psychiatric evaluation and the plan of treatment, but the physician (MD/DO) or non-physician practitioner must personally document the mental status examination, physical examination, and diagnosis. It will not always be possible to obtain all the suggested information at the time of evaluation. In such cases, the limited information that is obtained and documented, must still be sufficient to support the need for an inpatient level of care.The Plan of Treatment is the tool used by the physician and multi-disciplinary treatment team to implement the physician-ordered services and move the patient toward the expected outcomes and goals. Although the Plan of Treatment is a requirement, the format and specific items to be included are up to the provider. Documentation of the parameters below is suggested to support the medical necessity for the inpatient services throughout the patients stay.This individualized, comprehensive, outcome-oriented plan of treatment should be developed:within the first three (3) program days after admission;by the physician, the multidisciplinary treatment team, and the patient; and should bebased upon the problems identified in the physicians diagnostic evaluation, psychosocial and nursing assessments.The treatment plan should include:the specific treatments ordered, including the type, amount, frequency, and duration of the services to be furnished;the expected outcome for each problem addressed; andcontain outcomes that are measurable, functional, time-framed, and directly related to the cause of the patients admission.Treatment plan updates should show the treatment plan to be reflective of active treatment, as indicated by documentation of changes in the type, amount, frequency, and duration of the treatment services rendered as the patient moves toward expected outcomes. Treatment plan updates should be documented at least weekly, as the physician and treatment team assess the patients current clinical status and make necessary changes. Lack of progress and its relationship to active treatment and reasonable expectation of improvement should also be noted.The initial treatment plan and updated plans must be signed by the physician or non-physician practitioner and those mental health professionals contributing to the treatment plan.A separate progress note should be written for each significant diagnostic and therapeutic service rendered and should be written by the team member rendering the service. Although each progress note may not contain every element, progress notes should include a description of the nature of the treatment service, the patients status (behavior, verbalizations, mental status) during the course of the service, the patients response to the therapeutic intervention and its relation to the long or short term goals in the treatment plan. Each progress note should be legible, dated and signed, including the credentials of the rendering provider. It should be clear from the progress notes how the particular service relates to the overall plan of care.Physician progress notes should be recorded at each patient encounter and contain pertinent patient history, changes in signs and symptoms, with special attention to changes to the patients mental status, and results of any diagnostic testing. The notes should also include an appraisal of the patients status and progress, and the immediate plans for continued treatment or discharge. The course of the patients inpatient diagnostic evaluation and treatment should be inferred from reading the physician progress notes.Individual and group psychotherapy and patient education and training progress notes should describe the service being rendered, (i.e., name of group, group type, brief description of the content of the individual session or group), the patients communications, and response or lack of response to the intervention. Each progress note should reflect the particular characteristics of the therapeutic/educational encounter to distinguish it from other similar interventions.
