Read the fine print, my fren.
In the U.S. healthcare system, the people who actually decide whether your claim gets paid (or denied) are medical claims adjudicators—sometimes called claims examiners, claims analysts, or claims processors — who work for the insurance company.
Here’s exactly who touches it and in what order:
- Automated system (first pass)
Your claim hits the insurer’s computer system within hours of submission. Software instantly checks for basic errors (wrong patient ID, expired coverage, non-covered service code, etc.). About 60-70% of claims are auto-approved or auto-denied here with zero human eyes.
- Claims adjudicator/examiner (human decider)
If the system flags anything or it’s a complicated claim, it lands on a real person’s desk. This is the actual human being who determines “valid = paid” or “invalid = denied.”
- They verify:
- Was the service medically necessary? (They compare doctor’s notes against the insurer’s medical policy)
- Was prior authorization obtained if required?
- Is the diagnosis code supported by the procedure code?
- Was the provider in-network?
- Are there duplicate charges or unbundling violations?
- They have the authority to approve payment, pend the claim for more info, or deny it outright.
- Medical reviewer / nurse reviewer (for denials or high-dollar claims)
If the adjudicator thinks it should be denied or it’s over a certain dollar threshold (often $5k–$25k depending on the insurer), it goes to an RN or MD who works for the insurer. This person decides if the treatment was medically necessary using evidence-based guidelines (Milliman Care Guidelines, InterQual, or the insurer’s internal policies).
- Appeals department (if you fight the denial)
If you appeal, a different team (often including a physician advisor) re-reviews everything. This is a fresh set of eyes that can overturn the original decision.
So in short: the insurance company’s claims adjudicator is the primary person who determines if your claim is valid. They’re backed by automated rules on the front end and nurses/doctors on the back end for the tough calls.
According to the guidelines and existing law, it's not fraud to deny a claim unless it's proven in a court of law.
