Reporting of Modifier 76 and 77 With Laboratory Services

The policies will be revised to better align with CMS and the AMA correct coding guidelines. Duplicate laboratory codes reported with modifiers 76 or 77 will no longer be reimbursed. This aligns with CMS’ policy which denies laboratory services when reported with either modifier 76 or 77, citing that other modifiers (e.g., modifiers 59 or 91) are more appropriate.
