About Behavioral Health billing
Behavioral health codes are time-based. Mental Health Parity law requires insurance coverage at the same level as medical/surgical care.
Request the session note. Verify face-to-face time matches the billed code. Appeal denials citing the Mental Health Parity and Addiction Equity Act (MHPAEA).
How to dispute a CPT 96150 overcharge
- Request the itemized bill. You are entitled to a detailed line-by-line bill showing every CPT code billed. Ask in writing.
- Compare to Medicare allowable. If the charge exceeds 150% of Medicare ($44), you have grounds to dispute.
- Request documentation. For E&M codes, ask for the visit note. For procedures, ask for the operative report. The documentation must justify the code billed.
- Send a formal dispute letter. Cite the specific discrepancy between the documentation and the code. Reference Medicare rates and NCCI edits where applicable.
- Follow up in writing. Give the provider 30 days to respond. If they don't, escalate to the state attorney general and insurance commissioner.
