Denial code

PR 27

Coverage had ended on the date of service.

Usually lost PR CO 27

What PR 27 means

PR — Patient responsibility — this one goes on the patient statement.

So the balance is billable to the patient, provided your advance notice was in order. Check that before the statement goes out. Billing a patient for something you contractually agreed to absorb is the expensive mistake on this code.

The same code, a different prefix. 27 also arrives as CO 27. The reason for the denial is the same. The prefix decides who pays for it, so the next step is not the same. If your remit says CO 27, read that page instead.

Is it worth appealing?

Usually lost. Recoverable only with unusual evidence. Triage by dollar value.

Why it fires

In the order we see it.

  1. Coverage had terminated before the date of service.

What to do

Re-verify eligibility. If another plan was active, rebill that payer.

What actually wins it

The documentation, not the argument.

Evidence another plan was active, and a rebill to that payer.

The common mistake. Re-verify eligibility before writing this off. A termination date in the payer's system is sometimes wrong, and the patient often has other coverage.

Where this comes from. This is our own reading of the code, not the payer's and not a copy of the standards text. We classify it from how these denials actually resolve. Where we are unsure, we say so rather than guessing.
