Repeating a test? Check with your MAC, use correct modifier and no do-overs.

Why This Topic Matters

Repeat testing can trigger denials or incorrect reporting if the wrong modifier is used, if a payer has special line-item preferences, or if the service falls under a different reporting rule. The article helps readers recognize that payer policy, documentation, and code descriptor context all affect how repeated services are reported.
