Denial Management and Appeals
Turning denials into recovered revenue
Denial management is a structured process: identify, categorize, prioritize, correct or appeal, and prevent recurrence. Candidates must understand denial types: clinical (medical necessity), technical (registration, coding, eligibility), and contractual (bundling, non-covered). Each requires a different workflow and timeline.
Concepts to master
- Root cause analysis and denial reason codes (CARC/RARC).
- Appeal levels and payer-specific deadlines.
- Clinical documentation supporting medical necessity appeals.
- Prevention metrics: denial rate, overturn rate, days to appeal.
- Payer contracts and appeal rights.
Traps in questions
A common trap is appealing a denial that should be corrected and rebilled, such as a wrong member ID. Another is missing the appeal deadline because the denial was placed in a work queue without triage. Questions may also test whether a denial for "not medically necessary" can be overturned with a coding change alone; usually it requires clinical documentation.
Rule of thumb
Correct technical denials; appeal clinical denials; prevent both with root-cause feedback to the front end and coding.
Worked example
A claim is denied for "service not covered" because the diagnosis code does not support medical necessity. The correct response is a clinical appeal with supporting documentation, not a code change, unless the documentation genuinely supports a different code.
