Medicaid Coverage and Coding Guides

Medicaid has limited coverage policies (LCPs) for certain laboratory tests. Tests subject to an LCP must meet medical necessity criteria in order to be covered.

When submitting lab orders, you must provide ICD-10 codes that indicate the patient’s condition and/or the reasons for ordering the test. If those reasons are not considered medically necessary by Medicaid, coverage may be denied.
