HCPCS Level II Modifiers


Level II modifiers provide further information about the procedure or service performed. It gives more specificity for the service or procedure rendered.

Modifiers are two-characters (either numeric or alphanumeric) in the sequence AA through VP, if the modifier has a letter in it, it’s a HCPCS modifier. If that modifier is entirely numeric, it’s a CPT modifier. These modifiers are annually updated by the CMS ( Centers for Medicare and Medicaid Services ).
