| RARC | Meaning |
|---|---|
| M143 | The provider must update license information with the payer. |
| MA47 | Our records show you have opted out of Medicare, agreeing with the patient not to bill Medicare for services/tests/supplies furnished. As result, we cannot pay this claim. The patient is responsible for payment. |
| MA56 | Our records show you have opted out of Medicare, agreeing with the patient not to bill Medicare for services/tests/supplies furnished. As result, we cannot pay this claim. The patient is responsible for payment, but under Federal law, you cannot charge the patient more than the limiting charge amount. |
| MA120 | Missing/incomplete/invalid CLIA certification number. |
| N95 | This provider type/provider specialty may not bill this service. |
| N115 | This decision was based on a Local Coverage Determination (LCD). An LCD provides a guide to assist in determining whether a particular item or service is covered. A copy of this policy is available at www.cms.gov/mcd, or if you do not have web access, you may contact the contractor to request a copy of the LCD. |
| N425 | Statutorily excluded service(s). |
| N450 | Covered only when performed by the primary treating physician or the designee. |
