Can all peer support services be billed?

Billing eligibility for peer support services depends on several factors, including client eligibility, medical necessity, the specific service provided, and payer policies. Always verify requirements for each service date and payer.

Modifiers provide additional information about a service or procedure, clarifying circumstances. Specific modifiers may be required by New Mexico Medicaid or MCOs for peer support services to ensure accurate processing and payment.

It's advisable to regularly check the New Mexico Medicaid website and applicable MCO provider manuals for updates to peer support service policies and billing guidelines, as these can change periodically.
