Billing rules
- Up to 4 units per date of service. Each unit = one validated scale administered, scored, and documented. Four is Medicare's Medically Unlikely Edit ceiling, published with adjudication indicator 3, which makes it a clinical benchmark rather than an absolute bar. Commercial limits vary by contract.
- Add-on, not a primary service code. Bill alongside psychotherapy (90832/90834/90837), E/M (99213/99214), or evaluation (90791/90792).
- Scoring and documentation are required. The clinician's interpretation in the note is what the code reimburses, not the patient self-completing the form.
- Patient self-administration is acceptable. The patient can complete the scale on tablet, paper, or remotely; the clinician scores, interprets, and documents.
- Does not bill psychotherapy time. 96127 reimburses the brief-scale workflow; the session itself is billed separately under the primary service code.
