Medicare’s billing rules and regulations are consistent nationwide. Not so Medicaid. Medicaid services, billable codes, individuals credentialed to provide services, and benefits are state specific. For instance, in Connecticut non-physician mental health practitioners can not bill medicaid for telemedicine and health and behavior codes, while in Alaska they can.
Happily SAMHSA has created a tool for Medicare and Medicaid that identifies for every state what codes are billable, and which clinicians are credentialed to bill for those services.
