Non-Covered Service
Definition
A non-covered service is a medical procedure, treatment, or service explicitly excluded from a patient's insurance plan. The payer will not reimburse the provider for this service, and the patient becomes financially responsible for full payment unless advance notice is provided.
Why It Matters
Billing a non-covered service without advance notice creates financial risk and compliance exposure. Submitting claims for excluded services can result in denials and patient disputes. Identifying non-covered services upfront protects your revenue cycle and ensures transparent patient communication about costs.
How It Works
Insurance plans maintain explicit lists of excluded services. Common non-covered categories include cosmetic procedures, experimental treatments, lifestyle services, and certain screening tests. When you submit a claim for a non-covered service, the payer adjudicates it as a CO-50 denial or similar code and returns the claim unpaid. To bill the patient, you must provide a signed Advance Beneficiary Notice (ABN) before services are delivered. The ABN confirms the patient understands the service may not be covered and agrees to be responsible for costs. If no ABN is on file, patient financial responsibility may be invalid, and you absorb the cost.
Related Terms
Can you bill a patient directly for a non-covered service?
Yes, if you provide proper advance notice (ABN or notice of privacy practices). Patients must consent to be responsible for payment before services are rendered. Without advance notice, the claim must be submitted to insurance even if denied, and you may absorb the cost.
How do I know if a service is covered before billing?
Verify coverage through the payer's website, call the authorization line with patient information, or use a real-time eligibility tool. Check the patient's plan documents and any prior authorization requirements. Services marked as 'exclusion' or 'limitation' in the plan are non-covered.
