Commercial Coverage and Coding Guides

Commercial health plans publish limited coverage policies (LCPs) for certain laboratory tests. Tests subject to a commercial LCP must meet medical necessity criteria in order to be covered by the plan.

When submitting lab orders for a test included in commercial payer policies, please ensure that all ICD-10 codes provided represent the signs, symptoms, or conditions that prompted the request. If the indications and limitations of the payer's policy are not met, your patient may be responsible for payment.
