What actually differs in Maryland
Credentialing advice written for "most states" tends to be wrong here in specific, expensive ways. These are the rules that only apply in Maryland.

- Behavioral health carve-out (single statewide ASO) COMAR 10.67.08.02
-
Maryland carves specialty behavioral health OUT of its HealthChoice MCO package: physical health runs through the 9 HealthChoice MCOs under an 1115 waiver, while specialty BH is paid fee-for-service by one statewide ASO (COMAR 10.67.08.02). The ASO is Carelon Behavioral Health, effective January 1, 2025, replacing Optum Maryland. Do not cite Optum as Maryland's current ASO.

- HealthChoice MCO roster
-
Maryland's 9 HealthChoice MCOs (physical health; BH is carved out to Carelon): Aetna Better Health of Maryland, Wellpoint Maryland (formerly Amerigroup), CareFirst BCBS Community Health Plan Maryland, Jai Medical Systems, Kaiser Permanente (closed-model, limited external participation), Maryland Physicians Care, MedStar Family Choice, Priority Partners, and UnitedHealthcare Community Plan of Maryland. Molina is NOT a Maryland HealthChoice MCO.

- Medicaid enrollment portal
-
Maryland Medicaid provider enrollment runs through ePREP (electronic Provider Revalidation and Enrollment Portal), screen first, always: providers may not render services until enrolled, and are at financial risk for services delivered before their MA number is active. Behavioral health enrollment is two steps: enroll in Medicaid via ePREP, then register with the ASO's Carelon Provider Digital Front Door for authorizations and claims. Revalidation also runs in ePREP on the 5-year federal floor.

- Commercial prompt-credentialing law Md. Code, Ins. § 15-112
-
Maryland's prompt-credentialing statute (Insurance § 15-112) binds commercial carriers only: within 30 days of receiving a completed application the carrier must send written notice of intent to continue or a rejection, and if it continues it has 120 days from that notice to accept or reject the provider. Critically, § 15-112 does NOT reach the Medicaid HealthChoice MCOs or the BH ASO (Carelon). Medicaid credentialing is governed by the HealthChoice MCO Agreement, COMAR 10.67 and 42 CFR 455 instead. Do not invoke the 30/120-day clock against an MCO or the ASO.

- Non-independent clinician billing (strict)
-
Maryland is the strict case: clinicians who are not independently licensed (LGPC, LMSW, LMFT, LGADC, LCSW. Note LCSW-C is the independent social work license) cannot enroll individually in Maryland Medicaid, cannot be paid in individual or group practice, and their supervisors cannot bill for them either. The only door is a licensed facility (e.g. an OMHC): facilities may be reimbursed for services delivered by supervised, not-yet-independent staff. Going solo is a dead end until full independent licensure.

- Behavioral health licensing boards
-
Master's-level behavioral health licensure sits in two Maryland boards: the Board of Professional Counselors and Therapists (LGPC entry/supervised, LCPC independent, plus LGMFT/LCMFT and LGADC/LCADC) and the Board of Social Work Examiners (LMSW, LCSW, and LCSW-C, the independent clinical license). The BOPC's online application system launched July 1, 2026; no paper or emailed applications are accepted after June 20, 2026.

- Counseling Compact status
-
Maryland has enacted the Counseling Compact but is not yet issuing or receiving privileges. As of July 2026 the live compact states are only AZ, GA, IN, LA, MN and OH. Compact status is volatile; re-check before relying on it.

ePREP, transitioning to MPRIME
Maryland currently enrolls providers through ePREP, with the MPRIME replacement scheduled to take over in October 2026. The operating vendor for the new system has not been publicly named, so expect process changes late in 2026.
From PayerReady's 50-state Medicaid enrollment platform research, verified July 2026. Portal contracts change; where an operator is in transition or not publicly confirmed, we say so rather than guess.
