Processing a Medical Insurance Claim or Prior Authorization

Step-by-Step Procedure

1. 1

   Verify the patient's insurance eligibility and coverage details before or at the visit, not after the claim is already submitted.

2. 2

   Confirm the correct ICD-10 diagnosis code(s) and CPT procedure code(s) match what was actually documented by the provider — codes are selected based on documentation, not assumed from the visit type.

3. 3

   Check whether the ordered procedure or medication requires prior authorization under the patient's specific plan before scheduling or dispensing it.

4. 4

   If prior authorization is required, submit the request with the complete clinical documentation the payer requires (diagnosis, prior treatments tried, medical necessity) rather than a bare request.

5. 5

   Submit the claim through the correct billing workflow and track its status rather than assuming it processed correctly.

6. 6

   If a claim is denied, read the denial reason code carefully to determine whether it's a correctable data issue (wrong code, missing modifier) or requires an appeal with additional clinical support.

7. 7

   Communicate with the patient about any coverage issue, cost estimate, or delay in a timely, honest way — don't let them find out about a denial from a surprise bill.

Quality Checkpoints

• ✓

  Insurance eligibility is verified before the service is rendered whenever possible, not discovered as a problem afterward.

• ✓

  ICD-10 and CPT codes match what the provider actually documented, not an assumption based on the chief complaint.

• ✓

  Prior authorization requirements are checked before scheduling anything that needs one.

• ✓

  Denials are read and categorized correctly (fixable data error vs. true coverage denial) before resubmitting or appealing.

Common Mistakes

• ⚠

  Submitting a claim without checking whether the specific procedure needs prior authorization under that patient's plan, resulting in a preventable denial.

• ⚠

  Coding from the visit reason instead of from what the provider actually documented, which can create a mismatch that triggers a denial or an audit flag.

• ⚠

  Resubmitting a denied claim unchanged, hoping it clears on a second pass instead of fixing the actual data or documentation issue.

• ⚠

  Not telling the patient about a likely out-of-pocket cost or prior-auth delay until after the fact.

On-the-Job Tips

• →

  Keep a running list of which payers in your area are strict about which procedures need prior authorization — this varies by plan and changes periodically.

• →

  A clear, specific update to the patient about a coverage delay ("your plan requires approval before this procedure, typically 3-5 business days") reduces confusion and complaints far more than a vague "we're working on it."
