PR-26 denial code
The expenses predate the coverage — service rendered before the policy's effective date, so the plan says it hadn't started paying for this patient yet, and the bill is theirs.
PR — Patient Responsibility. The amount is the patient's to pay: deductible, coinsurance, or copay. These are not denials, and they are collectible.
Why you got it
- 1The visit happened before the plan's effective date — new-job coverage that started on the first of the month after the visit, or a plan picked during enrollment that hadn't begun.
- 2The wrong plan year's card: the patient presented coverage that would exist soon rather than coverage that existed then.
- 3An effective date recorded wrongly on the payer's side.
How do I fix a PR-26 denial?
- Verify the actual effective date against the date of service. If the payer has it wrong, the patient's enrollment paperwork settles it — appeal with it.
- Check whether other coverage existed on the date of service — the previous employer's plan, COBRA that was elected, or Medicaid, whose retroactive eligibility can reach back and pay claims from before the application.
- If no coverage existed on that date, the balance is the patient's — a self-pay conversation, and better had early.
How to stop the next one
Eligibility verified against the date of service, not the date of scheduling. Coverage boundaries are exactly where a week-old verification lies to you.
Our diagnosis scrubber will not catch this one. PR-26 is driven by procedure codes, modifiers, or eligibility rather than by the diagnosis set — and procedure-side checking needs CPT codes, which aren’t included yet. We would rather tell you that than sell you a tool that quietly misses your most common denial.
If denials like this are a volume problem rather than a one-off, the denial management page explains how the paid workspace catches the coding causes on every claim, and the free ICD-10-CM lookup shows the coding notes behind any diagnosis code on the remittance.
