A modifier appended to a CPT code is used to:

b.Replace the diagnosis code on the claim
c.Indicate that a service was altered by a specific circumstance without changing the code's core meaning
d.Signal that the claim is being submitted late

Giải thích

Modifiers are two-character codes that provide additional information about a service, such as that a procedure was bilateral, was reduced, or was performed by more than one provider, without redefining the procedure itself. Correct modifier use supports clean claims and appropriate reimbursement. Omitting a needed modifier is a frequent cause of denials.
