A community mental health center (CMHC) certified by Medicare is a provider whose services Medicare Part B pays for "partial hospitalization services and intensive outpatient services furnished by a community mental health center (CMHC)" (42 CFR 485.900(a)(1)), under conditions of participation in 42 CFR Part 485, Subpart J. This page is for community mental health centers pursuing Medicare certification, or remediating an existing CMHC against those conditions. Integral Healthcare Solutions (IHS) drafts the CMHC policy set and survey evidence; your clinical leadership approves it and your organization files.

What is Medicare CMHC certification?

The governing text is 42 CFR Part 485, Subpart J, "Conditions of Participation: Community Mental Health Centers (CMHCs)" (sections 485.900 through 485.920), which we read in the current eCFR text (up to date as of September 30, 2026). CMS says it "established Conditions of Participation (CoPs) for the Community Mental Health Centers (CMHCs) effective October 29, 2014 (78 Fed. Reg. 64603, Oct. 29, 2013). The CMHC CoPs are located at 42 CFR 485.904 through 42 CFR 485.918" (CMS, Community Mental Health Centers). CMS links State Operations Manual Appendix F as the CMHC interpretive guidance; this page does not summarize it.

The provider agreement is narrow. A CMHC is a provider for provider-agreement purposes "but only with respect to providing partial hospitalization services and intensive outpatient services" (42 CFR 485.900(a)(3)).

The conditions that drive most of the documentation:

• The 40 percent rule. The CMHC "Provides at least 40 percent of its items and services to individuals who are not eligible for benefits under title XVIII of the Act" (485.918(b)(1)(v)), and must submit "a certification statement provided by an independent entity that certifies that the CMHC's client population meets the 40 percent requirement" (485.918(b)(1)(v)(A)).
• Treatment teams and plans. "The CMHC must designate an interdisciplinary treatment team that is responsible, with the client, for directing, coordinating, and managing the care and services furnished for each client" (CMS, summarizing section 485.916). The active treatment plan is set "within 7 working days of admission to the CMHC" (485.916(b)) and reviewed at least every 30 calendar days (485.916(d)).
• Quality. "The CMHC must develop, implement, and maintain an effective, ongoing, CMHC-wide data-driven quality assessment and performance improvement program (QAPI)" (CMS, section 485.917).
• Emergency preparedness. "The CMHC must establish and maintain an emergency preparedness program that meets the requirements of this section" (CMS, section 485.920).

Who needs CMHC certification and what triggers it

The buyer is a community mental health center that wants to furnish partial hospitalization or intensive outpatient services to Medicare beneficiaries, or one that already holds a provider agreement and needs to close gaps. The triggers:

• Initial enrollment. CMS's processing instructions cover "CMHC Initial Form CMS-855A Applications" (CMS Transmittal 11574), and the independent 40 percent certification is required "upon initial application to enroll in Medicare" (42 CFR 485.918(b)(1)(v)(B)).
• Revalidation, when the 40 percent certification is required again "as a part of revalidation" (485.918(b)(1)(v)(B)).
• Remediation of an existing CMHC whose treatment planning, QAPI or emergency preparedness records do not match Subpart J.

How IHS helps

IHS ties each finding and each drafted policy to a section of 42 CFR Part 485, Subpart J.

1. Gap assessment. IHS reads your operation against the CMHC conditions of participation, using questionnaires on services, admission, discharge and staffing.
2. Document and evidence mapping. IHS crosswalks each condition to the record that shows it is met.
3. Drafting. IHS drafts the client rights, admission, discharge, treatment-planning and QAPI policies, with clinical content for your clinical director to review and approve.
4. Mock survey. IHS reviews sample records against the conditions, including the 7-working-day and 30-day treatment plan clocks, and lists what is missing.
5. Readiness support. IHS drafts correspondence for your organization to send.

What you supply: your service model, staffing and credentials, current policies, sample records, and clinical leadership approval.

The limit: CMHC certification is distinct from CCBHC designation, and your organization chooses between them. The independent 40 percent certification comes from an independent entity your organization engages, and billing questions go to your reimbursement staff. IHS drafts; your organization files and handles all correspondence with CMS and the surveying agency.

What to have ready

Each item ties to 42 CFR Part 485, Subpart J (current eCFR text, up to date as of September 30, 2026) or the CMS CMHC page (last modified December 30, 2024).

• A service description covering the partial hospitalization and intensive outpatient services the provider agreement is limited to (42 CFR 485.900(a)(3)).
• Client population data showing the CMHC provides at least 40 percent of its items and services to individuals who are not eligible for benefits under title XVIII of the Act (485.918(b)(1)(v)).
• An independent entity lined up to provide the 40 percent certification statement for the initial application (485.918(b)(1)(v)(A)-(B)).
• A written designation of the interdisciplinary treatment team (CMS, section 485.916).
• An admission workflow that produces the active treatment plan "within 7 working days of admission" (485.916(b)).
• A review calendar that brings each active treatment plan back at least every 30 calendar days (485.916(d)).
• QAPI data and the program that uses it (section 485.917).
• An emergency preparedness program (section 485.920).
• Your CMS-855A enrollment package (CMS Transmittal 11574).

The introductory call is the place to walk through this list against your own center.

How CMHC certification compares with CCBHC

The Certified Community Behavioral Health Clinic (CCBHC) is a separate model with its own requirements. SAMHSA says "CCBHCs are required to serve anyone who requests care for mental health or substance use, regardless of their ability to pay, place of residence, or age" (SAMHSA).

IHS's reading, October 2026: CCBHC is a separate SAMHSA and state model, not a Medicare CMHC provider agreement, based on the two programs' governing sources. Which one your organization pursues is its decision.

What CMHC certification costs

CMS does not publish a CMHC-specific certification fee on the CMHC page or in Subpart J. CMS's published fee is the Medicare enrollment application fee: "a $750.00 calendar year (CY) 2026 application fee for institutional providers that are initially enrolling in the Medicare or Medicaid program or the Children's Health Insurance Program (CHIP); revalidating their Medicare, Medicaid, or CHIP enrollment; or adding a new Medicare practice location" (Federal Register 2025-21877).

IHS's reading, October 2026: because a CMHC enrolls on the CMS-855A, which the fee notice covers, an initial CMHC enrollment pays the $750.00 fee unless a hardship exception is granted. Under 42 CFR 424.514(a), the applicant submits the fee, a hardship exception request, or both, when it files. The independent 40 percent certification is a separate cost; CMS publishes no fee for it. Verify current fees with CMS.

What this is not

• IHS does not provide the independent 40 percent certification statement, and does not give billing or reimbursement advice.
• IHS does not file enrollment or correspond with CMS or the surveying agency. Your organization submits; IHS drafts.
• This page is not legal advice, and IHS's work does not guarantee a certification decision.

Frequently asked questions

What is a community mental health center (CMHC) under Medicare?

It is a provider whose partial hospitalization and intensive outpatient services Medicare Part B pays for (42 CFR 485.900(a)(1)). A CMHC is a provider for provider-agreement purposes "but only with respect to providing partial hospitalization services and intensive outpatient services" (42 CFR 485.900(a)(3)).

What services can a Medicare-certified CMHC bill?

Partial hospitalization and intensive outpatient services. Medicare Part B pays "for partial hospitalization services and intensive outpatient services furnished by a community mental health center (CMHC)" (42 CFR 485.900(a)(1)). Billing questions beyond that belong with your reimbursement staff.

What are the CMHC conditions of participation?

CMS says the CMHC conditions of participation took effect October 29, 2014, and "are located at 42 CFR 485.904 through 42 CFR 485.918" (CMS). They cover the interdisciplinary treatment team and active treatment plan, QAPI and the 40 percent requirement, among others; emergency preparedness is at section 485.920.

What is the CMHC 40 percent rule and who certifies it?

The CMHC "Provides at least 40 percent of its items and services to individuals who are not eligible for benefits under title XVIII of the Act" (42 CFR 485.918(b)(1)(v)). An independent entity provides the certification statement, which is required "upon initial application to enroll in Medicare, and as a part of revalidation" (485.918(b)(1)(v)(B)).

How quickly must a CMHC complete the active treatment plan, and how often is it reviewed?

The plan is established "within 7 working days of admission to the CMHC" (42 CFR 485.916(b)) and reviewed at least every 30 calendar days (485.916(d)). A mock survey of sample records checks both clocks.

What does a CMHC QAPI program need to show?

CMS says "The CMHC must develop, implement, and maintain an effective, ongoing, CMHC-wide data-driven quality assessment and performance improvement program (QAPI)" (CMS, section 485.917). Read section 485.917 for the full condition before you build the program.

CMHC certification versus CCBHC: which one does my organization need?

They are different programs. A Medicare CMHC holds a provider agreement limited to partial hospitalization and intensive outpatient services, while SAMHSA says "CCBHCs are required to serve anyone who requests care for mental health or substance use, regardless of their ability to pay, place of residence, or age" (SAMHSA). The choice is your organization's.

What emergency preparedness rules apply to CMHCs?

"The CMHC must establish and maintain an emergency preparedness program that meets the requirements of this section" (CMS, summarizing 42 CFR 485.920). IHS drafts the program documents for your leadership to approve.
