PR-97 means the insurer says this service is already included in the payment for another procedure — but you're being billed directly for it as patient responsibility, which is unusual and frequently incorrect.

The plain English translation — and why this code is often applied incorrectly.
PR-97 combines a bundling determination (the "97" reason — this service is already paid for as part of another procedure) with a "PR" group code, meaning the insurer is telling you that you owe the bundled amount directly, rather than the provider absorbing it.
This is unusual. Bundling denials almost always carry a CO (Contractual Obligation) group code, because in-network providers agree by contract not to bill patients for amounts reduced due to bundling edits. Seeing a "PR" on a bundling denial typically means one of two things: the provider is out-of-network and not bound by that contractual restriction, or the claim was processed and billed incorrectly.
Either way, PR-97 deserves scrutiny before you pay it — it is one of the least "automatically legitimate" denial codes in medical billing.
A bundled charge billed to the patient is rarely straightforward — here's why.
If your provider is in-network, their contract with the insurer typically requires them to write off bundled amounts as a contractual obligation — not bill you for them. If you're in-network and were billed under PR-97, this is very likely a billing system error that your provider's office can correct by resubmitting the claim with the correct adjustment code.
Just like CO-97, a PR-97 denial can result from a missing modifier (59, XE, XS, XP, or XU) that should have indicated the two procedures were genuinely distinct. If the modifier was omitted, a corrected claim resubmission often resolves the entire issue — regardless of which group code was originally applied.
If the service was performed at an in-network facility by an out-of-network provider (common with anesthesiologists, radiologists, and assistant surgeons), federal No Surprises Act protections — and many state balance-billing laws — may prohibit billing you directly for this amount at all. This can make a PR-97 balance not just incorrect, but potentially illegal to collect.
Four elements that consistently reverse bundled charges billed to patients.
Check whether the billing provider was in-network at the time of service. If they were in-network, request in writing why a bundling adjustment was billed to you as PR instead of written off as CO per their network contract.
Ask the insurer to identify the exact CCI edit or bundling rule that triggered the PR-97 designation, and whether a modifier was submitted with the claim. This tells you and your provider's billing team exactly what needs to be corrected.
If the service involved an out-of-network provider at an in-network facility — anesthesia, radiology, pathology, assistant surgery — you may be protected from this bill entirely under federal balance-billing law. Note this explicitly in your dispute letter if it applies.
Send a written dispute to the billing office and/or insurer citing the incorrect group code, the missing modifier if applicable, or the balance-billing protection that applies. Do not pay a PR-97 balance until you've confirmed it is both correctly coded and legally collectible.
Because bundling adjustments are almost always a provider's contractual write-off, a bundled charge billed to the patient succeeds at overturning or eliminating the balance at some of the highest rates of any patient-responsibility code. Cases involving No Surprises Act protections score highest of all.
