BH medical necessity denials are killing your cash. Here's the fix.

What BH medical necessity actually requires

Documentation must establish: diagnosis from DSM-5-TR, functional impairment in life domains, treatment plan with measurable goals, evidence-based interventions matched to diagnosis, expected duration + frequency rationale, progress documentation supporting continued necessity.

The 3 documentation gaps that cause denials

Gap 1: progress notes that describe sessions but don't tie to treatment plan goals. Gap 2: treatment plan goals that aren't measurable. Gap 3: lack of objective functional improvement documentation supporting continued treatment necessity.

IOP and PHP specific requirements

Intensive outpatient + partial hospitalization carry concurrent review pressure. Document level-of-care justification continuously: why IOP vs outpatient, why PHP vs IOP, criteria for step-down. Concurrent review denials concentrate where step-down criteria aren't documented.

SUD-specific medical necessity

SUD treatment under 42 CFR Part 2 requires ASAM dimension-based level-of-care justification. Most SUD denials trace to missing ASAM documentation, not clinical issue. Standardize ASAM template in EHR.

Parity-based appeals

Mental Health Parity Act (MHPAEA) requires parity between BH and medical/surgical coverage. Denials that don't meet parity requirements are challengeable. Successful parity appeals can overturn systemic denial patterns.
