Medical necessity checklist for behavioral health

Diagnosis and assessment

0/4

A current DSM-5-TR / ICD-10-CM diagnosis is documented and supported by assessment findings.

The diagnosis on the claim matches the diagnosis on the active treatment plan.

Functional impairment is described in concrete terms (work, school, self-care, relationships, housing).

A standardized measure was administered at intake and at a regular cadence since.

The plan was in effect (not expired) on the date of service.

Goals are in the client's words and objectives are measurable, with target dates.

Interventions name the modality, frequency and responsible staff.

Client (and guardian, where required) participation or signature is documented.

The note names the goal or objective addressed in this session.

The intervention is a named, skilled technique — not 'supportive counseling'.

The client's response is specific and, where possible, measurable.

Start/stop or total time supports the code and units billed.

Risk is addressed whenever it was discussed or indicated.

The text is individualized — not copied from prior notes or other clients.

Continued stay and level of care

0/4

The note or review explains why care continues at this level and frequency.

Barriers to progress and plan adjustments are documented.

For SUD, level of care is supported by a current ASAM assessment (dimensions 1–6).

Discharge criteria are defined, so progress can be measured against an end point.

Signature and supervision

0/3

Signed with name, credentials and date within your required window.

Supervisor co-signature is present for pre-licensed staff.

The rendering clinician's credential is allowed to bill this code for this payer.

'Medically necessary' has no single federal definition for behavioral health. Medicare, each state Medicaid program and each commercial payer write their own criteria. But they test the same underlying question: was this service reasonable and necessary to treat a diagnosed condition, and does the record prove it?

The checklist above is built from common elements across payer criteria, the CMS Program Integrity Manual and federal audit findings. Use it on a sample of charts each month. A chart that passes all of it will survive most reviews; one that fails three or more items is worth a supervisor's attention.

How to run a monthly chart review

Sample at least five charts per clinician per quarter, weighted toward high-volume codes (90837, H-codes) and new staff.
For each chart, review the active plan and the three most recent progress notes against the checklist.
Record failures by item, not just by chart, so patterns show up (for example, 'no named intervention' across a whole team).
Share results in supervision, with examples of a passing note from the same clinician when possible.
Re-check the same items the following quarter.

The three failures we'd fix first

Undocumented time, expired or missing plans, and cloned text. They account for a large share of federal and state recoupments, they're objective (no reviewer judgment required), and they're preventable at the point of signing.

Run these checks on every note, automatically.

Note checks apply your rules at the moment of signing — on 100% of notes, with one-click fixes that cite the session.
