What is denial code CO-150?
CO-150 means the payer decided the documentation doesn't support the level of service billed, often a higher-level office visit. The payer may pay a lower level or nothing.
Remittance advice, claim line
| Service | Billed | Allowed | Paid | Adjustment |
|---|---|---|---|---|
| 99215 Office visit, high complexity | $260.00 | $128.40 | $102.72 | CO-150 $41.60, CO-45 $90.00 |
- The payer allowed the level-four rate. If the note documents high-complexity medical decision making or enough total time, the appeal quotes it.
Reason code 150 reads: Payer deems the information submitted does not support this level of service. It’s the denial behind downcoding.
How levels are judged
Office visits are leveled by medical decision making or total time on the date of the encounter. A payer reviewing a 99215 looks for high-complexity decision making, such as a serious problem, extensive data review and high-risk management, or enough documented time.
Appeal or accept?
Appeal when the note clearly supports the level billed, and quote the parts that do. Accept when the documentation is thin, because an appeal won’t fix the note. When the difference is small, the cost of the appeal can be more than the money at stake.
