Criteria, coverage stance, and billing/coding guidance for outpatient Psychiatric Partial Hospitalization Programs provided to BCBSNC members; applies to providers delivering PHP services seeking coverage determination and prior authorization.
New policy developed stating BCBSNC will provide coverage for Psychiatric Partial Hospitalization Programs (PHP) when medically necessary.
Updated timing requirement for physician or physician extender evaluation to within 7 treatment days of admission, or sooner as needed, and within 3 treatment days for specific circumstances (Withdrawal Management; MAT; Co-occurring mental health disorders; Medical co-morbidities).
Added description clarifying a partial hospitalization is a day or evening (non-residential) treatment alternative to a hospital admission and may be provided in hospital or free-standing settings at an inpatient program intensity level.
Billing/Coding section updated for clarity and alignment with reimbursement policy; no change to policy statement.
When Treatment is Covered
inv-01: Initial Therapy / Admission
Covered when ALL of the following are met:
inv-02: Admission functional criteria
Admission must ALSO meet all of the following behavioral/functional requirements:
inv-03: Continuation Therapy
Continued stay is covered when ALL of the following are met:
inv-04: Initial PHP coverage criteria (summary)
Covered when ALL of the following are met
See full policy for specific clinical criteria.
Operational requirement for timely physician/clinician evaluation.
Partial hospitalization programs are explicitly excluded from coverage when delivered via telehealth or virtual modalities. This policy states that Partial hospitalization programs are not covered for telehealth or virtual services, and providers should plan to deliver PHP services in-person at an approved facility setting to be considered for coverage.
Consistent with the policy revisions and exclusions, Partial hospitalization programs are not covered for telehealth or virtual services. This duplication reinforces that PHP coverage applies only to in-person, non-residential day or evening treatment settings.
Services for Psychiatric Partial Hospitalization Programs are considered not medically necessary when the member does not meet ALL of the coverage criteria listed in the "When Treatment is Covered" section of this policy. If any required admission or continued-stay criterion is not satisfied, PHP services should be considered non-covered for medical necessity purposes.
Any services that do not meet the policy's medical necessity criteria are excluded from coverage. The policy affirms that coverage is contingent on meeting the specified medical criteria and guidelines, and services failing to meet those criteria, including telehealth/virtual PHP, are not covered.

Provider Responsibilities and Authorization
Prior authorization may be required
Coverage for Psychiatric Partial Hospitalization Program (PHP) services may be subject to prior authorization by Blue Cross Blue Shield of North Carolina or its designee; applicable service code listed is H0035.
- Applicable service code: H0035 (facility per diem).
- Prior authorization may be required before services are rendered.
Coverage requires medical necessity
BCBSNC will provide coverage for Psychiatric Partial Hospitalization Programs (PHP) only when the service is determined to be medically necessary because the medical criteria and guidelines listed within the policy are met.
- Coverage contingent on meeting all applicable admission and continued-stay criteria in the policy.
Step‑therapy: lower‑level failure not required
Failure of treatment at a less intensive level of care is not a prerequisite for PHP coverage, though documentation of prior therapeutic trials or inability to adhere to lower levels may be relevant to the admission decision.
- Do not assume a prior lower-level trial is required before admission; document prior treatments and reasons they were insufficient when relevant.
Provide complete clinical documentation for admission requests
Ensure all required pre-admission and ongoing documentation is available to support medical necessity determinations and authorization requests.
- Include clinical documentation that demonstrates the DSM diagnosis is the primary focus, need for minimum 20 hours/week and 5 days/week, functional impairments, and community supports insufficiency.
- Document cognitive ability to engage, supervisory/licensure status, and multidisciplinary treatment plan timing.
Submit full medical records when requested
BCBSNC may request medical records to determine medical necessity; when records are requested, letters of support or explanation can be useful but are not sufficient unless they include all specific information needed to make the determination.
- Be prepared to supply full medical records and the specific clinical details outlined in the policy rather than relying solely on letters of support.
Timely physician/physician‑extender evaluation required
A physician or physician extender must evaluate the client within 7 treatment days of admission, or sooner as clinically needed; evaluation is required within 3 treatment days of admission for Withdrawal Management, Medication Assisted Treatment (MAT), co-occurring mental health disorders, or medical comorbidities.
- Document the date and provider of the physician/physician‑extender evaluation in the medical record.
- For the specified circumstances (Withdrawal Management, MAT, co-occurring disorders, medical comorbidities), ensure evaluation occurs within 3 treatment days and is documented.
Denial risk if coverage criteria not met
Services are considered not medically necessary when members do NOT meet ALL the criteria listed in the 'When Treatment is Covered' section; failure to meet any coverage criteria is a denial trigger.
- Verify the member meets every admission and continued‑stay criterion (e.g., DSM diagnosis focus, minimum hours/days, functional impairment in at least two areas) before billing or requesting authorization.
- Lack of required documentation or unmet functional/clinical thresholds may result in non‑coverage.
Telehealth/virtual PHP services are excluded
Partial hospitalization programs are not covered for telehealth or virtual service delivery; PHP must be provided as an in‑person day or evening, non‑residential program.
- Do not submit claims or authorization requests for PHP delivered via telehealth/virtual modalities.
- Provide documentation that services were delivered in-person at a hospital or free‑standing facility as required.

Background and Scope
Partial Hospitalization Programs (PHP) are structured, non-residential day or evening treatment alternatives to hospital admission designed to deliver clinical diagnostic and treatment services at an inpatient program intensity level. PHPs may be rendered in either hospital or free-standing facility settings and provide multidisciplinary care intended to manage acute psychiatric symptoms, medication and safety needs, and to prepare members for transition to lower levels of care.
