What Does PR-186 Mean?

With PR (Patient Responsibility), the level-of-care difference has been assigned to the patient. This may occur when the patient requested or continued a higher level of care against the payer's determination. The patient is responsible for the cost difference between the billed and approved levels.

CARC 186 appears when the payer downgrades the level of care on a claim after reviewing the clinical documentation. Rather than paying at the billed level (such as inpatient, ICU, or skilled nursing), the payer determined a lower level was medically appropriate — for example, observation instead of inpatient, step-down instead of ICU, or home health instead of skilled nursing.

This is a partial payment adjustment, not a full denial. The payer pays at the reduced level of care and denies the difference. Level-of-care downgrades are among the most impactful adjustments for hospitals and facilities because the payment difference between levels can be substantial. The most effective response is a clinical appeal with documentation supporting the billed level of care.

How to Resolve

  1. Verify the PR assignment Confirm the payer correctly assigned the level-of-care difference to the patient.
  2. Communicate with the patient Explain the level-of-care determination and the resulting financial responsibility.
  3. Collect from the patient Send a statement and follow your collection process. Offer payment plan options for large balances.
Do Not Appeal This Code

Level of Care Change Adjustment 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.
