What are modifiers in Orthopaedics billing and why are they game changers?
Modifiers are simply two-character designators that point towards a change in how the code for 
the procedure or services should be applied for the claim. When put to use strategically, modifiers 
can bring accuracy and detail to the record of the medical transaction. When misused, they can 
lead to claim denials, refunds & fines (in rare cases), and investigators.
Modifiers are two digit codes with two levels:
• Level I Modifiers: Usually known as CPT Modifiers and have two numeric digits and are updated 
annually by AMA – American Medical Association. CPT modifiers are used as an additional 
supplement to the information or adjust care descriptions to give extra details about a procedure 
or specific provided service to a patient.
• Level II Modifiers: Level II modifiers are HCPCS Modifiers consisting of two digits (Alpha / 
Alphanumeric characters) in the range AA to VP. These modifiers are annually updated by CMS – 
Centers for Medicare and Medicaid Services.
To get the right revenue through your Orthopaedic practice needs in-depth knowledge and the 
use of code modifiers wherever suitable and permissible. Modifiers are used in the main 
procedure code to show that the procedure has been changed by a distinct factor. Modifiers can 
impact reimbursement. They are also the reason for claims not to play properly or deny if used 
incorrectly or not used, whenever necessary. Some modifiers are meant for Ambulatory Surgical 
Cenblueters only, some for physician practices, and some are for use by both provider types.
