Denial Code PR-279

Services not provided by Preferred network providers.

Source: X12 Claim Adjustment Reason Codes (CARC) & Group Codes. Maintained by the D3rx Clinical Billing Team.

What PR-279 means

The services were provided outside the plan's preferred (narrow) network, and under the PR group code the resulting balance is the patient's — typically because the patient chose a provider outside the member's preferred network.

Why PR-279 happens

  • Care from a provider outside the plan's preferred/narrow network
  • A tiered plan where non-preferred providers carry higher member cost
  • The patient elected a non-preferred provider despite network limitations
  • A provider not in the member's specific 'narrow' network tier

What to do when you get PR-279

  1. 1Confirm the provider's status relative to the patient's PREFERRED/narrow network (not just any network)
  2. 2Check whether No Surprises Act protections apply (emergency or certain facility-based care)
  3. 3If the provider was actually preferred-network but mis-tiered, correct/appeal instead of billing
  4. 4If the higher cost is a legitimate non-preferred choice, bill the patient after notice

PR group code: who absorbs the charge

Patient ResponsibilityMay be billed to the patient.

A PR adjustment is the patient's liability — a deductible, coinsurance, copay, or a non-covered amount the patient owes. It is collectible directly from the patient, ideally after advance notice for any non-covered service.

Appeal, correct, or write off PR-279?

PR-279 is collectible from the patient when they chose a non-preferred-network provider and the choice isn't legally protected. Verify the provider's preferred-network/tier status first — a mis-tiered preferred provider is an appeal, not a patient bill — and apply No Surprises Act protections to emergencies and certain facility-based services. Where the non-preferred choice was the patient's, bill the patient with advance notice.

Timing & deadlines

If appealing a network-tier error, use the payer's window (commercial ~180 days from the remittance). There is no payer deadline on a legitimate PR balance, but confirm surprise-billing protections before billing the patient.

Example

A tiered plan member sees a provider outside the preferred network, and the claim returns PR-279 for the higher non-preferred cost. If the choice was the patient's and not protected, the balance is theirs; if the provider was actually preferred-tier, the network record supports an appeal.

Prevent PR-279 going forward

  • Verify preferred/narrow-network and tier status before scheduling
  • Inform patients of higher costs for non-preferred providers in advance
  • Apply No Surprises Act protections to emergency and facility-based care
  • Keep network-tier data current per payer

Code families most affected

  • Narrow-network and tiered-plan claims
  • Non-preferred-provider services
  • Member-elected out-of-preferred-network care

Payer notes

PR-279 specifically concerns the PREFERRED (narrow) network and is close kin to PR-242 (network/PCP). Confirm the provider's preferred-tier status and any surprise-billing protections before billing the patient.

CARC/RARC definitions are the standardized X12 set; group-code semantics follow the X12 Claim Adjustment Group Code standard. Filing and appeal windows vary by payer — the standard anchors shown (Medicare redetermination 120 days from the remittance; Medicare timely filing 12 months from date of service; most commercial payers ~90-180 days) are general references, not a guarantee for any specific plan.
