Behavioral Billing® Credentialing Guide
Wellpoint Maryland
Credentialing and revenue-cycle enrollment reference for behavioral health and speech therapy practices. Start with your provider type: the credentialing route may differ even when the insurance brand is the same.
Choose the correct provider pathway
Mental / behavioral health and speech therapy can sit in different payer networks even under the same insurance brand.
Mental / Behavioral Health provider
Behavioral-health credentialing route
Maintain Maryland Medicaid enrollment. For specialty behavioral health, verify Carelon registration/participation because specialty BH is carved out from the HealthChoice MCO.
Open BH credentialing source ↗Speech Therapy provider
Speech / therapy credentialing route
Maintain Maryland Medicaid enrollment for the SLP/provider group. Ages 0–20 route speech therapy through Maryland Medicaid FFS/EPSDT; age 21+ follows the MCO's network and benefit rules.
Open speech credentialing source ↗Where the pathways differ: Do not use the HealthChoice MCO's BH pathway as a universal route. Specialty BH may be Carelon-administered, while pediatric SLP is state FFS/EPSDT.
