PR-26: Expenses incurred prior to coverage.
The date of service falls before the patient's insurance coverage actually began, so this policy is not responsible for the charge.
What the group code means
- PR
- Patient Responsibility. The amount may be billed to the patient.
Why it fires
- The patient's coverage effective date is after the date of service
- A waiting period applies before certain benefits become active
- Coverage was entered into the system with an incorrect, too-late effective date
Corrective actions, ranked
- 1
Verify the effective date
Confirm the exact coverage start date on the payer's eligibility system.
- 2
Identify prior coverage
Ask the patient what insurance, if any, was active on the actual date of service and rebill that payer.
- 3
Bill the patient if uninsured
If no coverage existed on that date, move the balance to patient responsibility per your self-pay policy.
Is it worth appealing
Appeal only if you can show the effective date on file is wrong or coverage was retroactively extended to include this date of service.
