Billing and coding: diagnoses and procedure codes
Since 2019 the codes live in the companion article rather than the LCD. Billing and Coding A56685 (Billing and Coding: Partial Hospitalization Programs) carries the diagnosis and procedure lists the contractor loads as the claims edit. CPT codes are shown as bare numbers because the descriptors are licensed by the AMA; HCPCS Level II descriptors are public and shown.

Coverage indications, limitations and medical necessity
Overview
• Partial hospitalization programs (PHPs) are structured to provide intensive psychiatric care through active treatment that utilizes a combination of the clinically recognized items and services. The treatment program of a PHP closely resembles that of a highly structured, short-term hospital inpatient program. It is treatment at a level more intense than outpatient day treatment or psychosocial rehabilitation. Programs providing primarily social, recreational or diversionary activities are not considered partial hospitalization.
• Partial hospitalization is active treatment that incorporates an individualized treatment plan which describes a coordination of services wrapped around the particular needs of the patient and includes a multidisciplinary team approach to patient care under the direction of a physician. The program reflects a high degree of structure and scheduling. According to current practice guidelines, the treatment goals should be measurable, functional, time-framed, medically necessary and directly related to the reason for admission.
• Eligibility for Medicare coverage of a PHP comprise 1 of 2 groups:
• Patients who are discharged from an inpatient hospital treatment program, and the PHP is in lieu of continued inpatient treatment. Where partial hospitalization is used to shorten an inpatient stay and transition the patient to a less intense level of care, there must be evidence of the need for the acute, intense, structured combination of services provided by a PHP.
• Patients who in the absence of partial hospitalization would be at reasonable risk of requiring inpatient hospitalization.
• Partial hospitalization services that make up a program of active treatment must be vigorous and proactive (as evidenced in the individual treatment plan and progress notes) as opposed to passive and custodial. Patients must also have the need for the active treatment provided by the program of services. It is the need for intensive, active treatment of his/her condition to maintain a functional level and to prevent relapse or hospitalization, which qualifies the patient to receive the services.
• This program of services provides for the diagnosis and active, intensive treatment of the individual’s serious psychiatric condition and in combination, are reasonably expected to improve or maintain the individual’s condition and functional level and prevent relapse or hospitalization. A particular individual covered service (described below) as intervention, expected to maintain or improve the individual’s condition and prevent relapse, may also be included within the plan of care (POC), but the overall intent of the partial program admission is to treat the serious presenting psychiatric symptoms. Continued treatment in order to maintain a stable psychiatric condition or functional level requires evidence that less intensive treatment options (e.g., intensive outpatient, psychosocial, day treatment, and/or other community supports) cannot provide the level of support necessary to maintain the patient and to prevent hospitalization.
• Patients admitted to a PHP do not require 24 hour per day supervision as provided in an inpatient setting and must have an adequate support system to sustain/maintain themselves outside the PHP. Patients admitted to a PHP generally have an acute onset or decompensation of a covered Axis I mental disorder, as defined by the current edition of the Diagnostic and Statistical Manual (DSM) published by the American Psychiatric Association (APA) or listed in Chapter 5 of the most current edition of the International Classification of Diseases (ICD). The disorder severely interferes with multiple areas of daily life. The degree of impairment will be severe enough to require a multidisciplinary intensive, structured program, but not so limiting that patients cannot benefit from participating in an active treatment program. The treating physician must certify the need for the structured combination of services provided by the program. This active treatment is required to appropriately treat the patient’s presenting psychiatric condition.
Covered Services
Items and services that can be included as part of the structured, multimodal active treatment program include:
• Individual or group psychotherapy with physicians, psychologists or other mental health professionals authorized or licensed by the State in which they practice (e.g., licensed clinical social workers, clinical nurse specialists, certified alcohol and drug counselors);
• Occupational therapy (OT) requiring the skills of a qualified occupational therapist. OT, if required, must be a component of the physicians treatment plan for the individual;
• Services of other staff (social workers, psychiatric nurses and others) trained to work with psychiatric patients;
• Drugs and biologicals that cannot be self-administered and are furnished for therapeutic purposes;
• Individualized activity therapies that are not primarily recreational or diversionary. These activities must be individualized and essential for the treatment of the patient’s diagnosed condition and for progress toward treatment goals;
• Family counseling services for which the primary purpose is the treatment of the patient’s condition;
• Patient training and education, to the extent the training and educational activities are closely and clearly related to the individuals care and treatment of his/her diagnosed psychiatric condition; and
• Medically necessary diagnostic services related to mental health treatment.

• Vocational training

Using this policy on a claim
Match the documented indication to the covered indications above before the service is scheduled, carry a diagnosis from the article's covered list on the claim line, and keep the elements the documentation section asks for in the record, because the contractor can request it later through medical review. A denial under this policy arrives as CARC 50 with remark N115; the LCD lookup guide walks through the appeal path and the Advance Beneficiary Notice rules, and the Palmetto GBA hub lists every other active policy from the same contractor.
Frequently asked questions
What does LCD L37633 cover?
• Partial hospitalization programs (PHPs) are structured to provide intensive psychiatric care through active treatment that utilizes a combination of the clinically recognized items and services. The treatment program of a PHP closely resembles that of a highly structured, short-term hospital inpatient program.

Which states does LCD L37633 apply to?
Palmetto GBA applies it to Medicare claims in AL, GA, NC, SC, TN, VA, WV. A Local Coverage Determination binds only the contractor that wrote it; the same service in another jurisdiction is judged under that contractor's own policy or, where none exists, claim by claim.
Which diagnosis codes support medical necessity under LCD L37633?
The companion billing and coding article A56685 lists 242 ICD-10-CM codes in 1 group that support medical necessity; the first 24 appear on this page and the complete list is in the article on cms.gov.
How do I appeal a denial under LCD L37633?
The remittance carries claim adjustment reason code 50 with remark code N115, naming the LCD. Compare the documented indication with the policy's covered indications and the article's diagnosis list, then file a redetermination within 120 days with the record attached; if the service genuinely falls outside the policy, the patient can be billed only when a valid Advance Beneficiary Notice was obtained before the service.
