Payers explain denials with standardized claim adjustment reason codes and remark codes. These codes are useful, but each payer uses them differently, and the same code can point to different root causes. Treat the code as the starting question, not the answer.
Patterns behind common denials
- Duplicate claims: the same service was billed twice, often after a resubmission was sent as a new claim
- Missing information: a required field, such as a referring provider or a diagnosis pointer, was left blank
- Timely filing: the claim arrived after the payer deadline, which varies by payer and contract
- Authorization missing: the service required approval that was not obtained or not referenced
- Modifier issues: a procedure code was submitted without a required modifier or with an inconsistent one
Build a denial log
For every denial, record the payer, the code, the service, the dollar amount, and the root cause once it is known. After a few months, the log shows which problems repeat. A single payer rule that causes the same denial every week is far more valuable to fix than dozens of individual appeals.
Always check the current code list published by the payer, because codes are updated. When in doubt, confirm the interpretation with the payer before resubmitting.
