What PR 242 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. 242 also arrives as CO 242. 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 242, read that page instead.

Is It Worth Appealing?

Usually recoverable. Appeal it. The money is usually there.

Why It Fires

In the order we see it.

Start my review
  1. No referral from the assigned primary care provider.

  2. The provider is out of network for that specific plan product, though in network for others from the same payer.

  3. Emergency or urgent care, where network rules are usually waived.

How to Appeal PR 242, Step by Step

Check whether the patient had a referral or an authorisation on file, or whether the care was urgent. Network denials are often won on one of those three.

  1. 1Step 1: Read the remark code. Find the remark code printed next to PR 242 on the 835 or EOB. It says what the payer wants back.
  2. 2Step 2: Find the cause. Match the denial to one of the 3 causes in Why It Fires above, and fix that one.
  3. 3Step 3: Take the first action. Check whether the patient had a referral or an authorisation on file, or whether the care was urgent. Network denials are often won on one of those three.
  4. 4Step 4: Attach the documentation. The referral or authorisation, with its date range. Documentation that the care was emergent, where that applies. The network participation record for that specific plan product.
  5. 5Step 5: Send the appeal before the deadline. Send it to the payer with the claim, the denial and the documentation, inside the payer's appeal window. See what an appeal letter must contain and the filing limits by payer.

The common mistake. Do not bill the patient before checking. Balance billing an out-of-network denial that was actually emergent is a compliance problem, not just a mistake.

PR 242 description

The provider was out of network, or not the patient's assigned primary care provider.

The provider was out of network, or not the patient's assigned primary care provider. 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.

This is our plain-English wording, not the official X12 text. X12 asserts copyright over the published descriptions, so we write our own and say what it means for the money rather than restating the code.

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.
