Check first

Check these before anything else

  • Cost-sharing terms in the patient's benefit plan
  • Allowed amount used in the calculation
  • Deductible / coinsurance / copay status
  • Patient-billing rules for non-covered services
  • ABN or waiver where required
  • Group code (PR) + CARC from the ERA/EOB

Verify payer-specific rules: Heads up

Patient liability depends on the member's specific benefit design and applicable regulations. Verify the calculation against the plan before billing, and never bill the patient for amounts the plan or law says the provider cannot collect.

AR Guide knowledge

What it means

The payer applied the member's cost-sharing or determined the patient is responsible for part or all of the charge. This is usually not a denial to appeal — it is an amount to bill the patient per the plan's rules, after verifying the calculation is correct.

AR Guide knowledge

Common causes

  • Deductible not yet met for the plan year
  • Coinsurance percentage applied per the benefit design
  • Copayment required for the service type
  • Non-covered service the patient may be billed for
  • Prior payer's patient responsibility not covered by the secondary plan

AR Guide knowledge

What AR should verify

  • Confirm the deductible, coinsurance, or copay matches the patient's benefit plan
  • Verify the allowed amount used for the calculation
  • Check the plan's patient-billing rules for non-covered services
  • Confirm the patient received proper notice where required (e.g., ABN)
  • Reconcile the member's payments against the adjustment

Recommended workflow

What to do next

  1. Bill the patient per the plan's patient-responsibility rules
  2. If the calculation looks wrong, request the claim calculation detail
  3. Do not bill the patient for amounts the plan or regulation says the provider cannot collect

Don’t assume

Avoid these shortcuts

  • The patient owes the full billed amount
  • The amount is wrong just because it is large
  • A patient-responsibility amount is appealable — it is usually billable per plan rules
  • The provider can always bill the patient
  • The calculation matches the plan — verify it before billing

AR Guide knowledge

Documentation

  • The patient's benefit plan showing cost-sharing terms
  • The claim calculation detail if the amount is disputed
  • ABN or waiver documentation where applicable

AR Guide knowledge

Escalation

  • Eligibility: confirm the benefit design and patient liability rules
  • Client: when the patient disputes the amount billed
  • Supervisor: when the same patient-responsibility pattern recurs

QA checkpoint

Confirm before closing

  • Verify deductible and cost-sharing at the time of service
  • Document patient notifications where required
  • Confirm the calculation before billing the patient
