Two vocabularies describing one episode
Clinical teams describe care in ASAM terms. Payers adjudicate codes, units, modifiers, authorization, and provider eligibility. Both descriptions must be internally consistent, but neither one produces the other automatically.
ASAM placement, diagnosis, treatment planning, medical necessity, and supervision remain the responsibility of qualified clinical professionals and the provider organization.
What billing operations verify
Operational review does not second-guess clinical judgment. It confirms that the paperwork surrounding the clinical decision holds together.
- Is the agency approved and enrolled for the service being billed?
- Is the service authorized for this patient, code, date range, and unit count?
- Is the rendering provider eligible and correctly rostered?
- Do documented duration and structure support the units submitted?
- Are payer, POS, modifier, NPI, and code combinations correct?
Careful language matters
New Mexico SUD IOP requirements commonly reference ASAM Level 2.1 placement criteria for eligible recipients. This does not mean every patient with a substance-use diagnosis qualifies for IOP or that every H0015 or S9480 claim is payable.
Providers should never select a higher level of care to increase reimbursement, and payers may apply ASAM criteria, state rules, and plan-specific utilization-management rules differently.
