What Does PR-203 Mean?

With PR (Patient Responsibility), the patient is financially responsible for the difference between the billed and approved service levels. This may occur when the patient chose to discontinue treatment early.

CARC 203 appears when the payer determines that the service billed was either not fully completed or was provided at a lower intensity or duration than what was coded on the claim. This could happen because a procedure was halted midway due to complications, the patient left against medical advice, the treatment plan was modified during the encounter, or the documentation does not support the full service as billed.

This is a payment adjustment — the payer reduces payment to match the actual level of service provided. If the service was genuinely discontinued or reduced, the claim should be rebilled with appropriate modifiers (such as modifier 52 for reduced services or modifier 53 for discontinued procedures).

How to Resolve

  1. Verify the adjustment Confirm the service was genuinely reduced or discontinued.
  2. Collect from the patient If the patient is responsible, communicate the charges and collect.
Do Not Appeal This Code

Discontinued or Reduced Service grouped under PR places the financial responsibility on the patient. The specific reason depends on the context of this adjustment — review any accompanying RARC codes for detail. Because this represents a placement of responsibility rather than a coverage denial, an appeal isn't the right action; verify the placement is correct before billing the patient.
