Modifier
A modifier is a two-digit alphabetic, numeric, or combined code used to add information or change the description of a service to improve accuracy or specificity in medical coding.
What is a Modifier?
A modifier is a two-character (letters or numbers) descriptor appended to a Current Procedural Terminology (CPT®) or Healthcare Common Procedure Coding System (HCPCS) Level II code. Modifiers provide additional information about a medical procedure, service, or supply without altering the basic meaning of the code itself. These descriptors are used by providers to indicate that a service or procedure has been altered by specific circumstances.
Modifiers are crucial for accurate medical coding and can affect reimbursement for providers. They can indicate various situations, such as a service having a professional or technical component, a procedure being performed by multiple physicians or in different locations, or a service being increased, reduced, or only partially performed. Proper use of modifiers helps prevent claim denials, delays in payment, and potential reimbursement loss.
What is the difference between a Modifier and CPT Code?
A modifier is a two-character descriptor appended to a CPT or HCPCS Level II code. It provides additional information about a medical procedure, service, or supply without changing the basic meaning of the code itself. CPT Code is a term that refers to the code to which a modifier is appended.
Modifiers are descriptors that add information to a code, while CPT codes are the primary codes themselves.
Modifiers provide details about how a procedure was altered by specific circumstances, whereas a CPT code represents the core procedure or service.
The proper use of modifiers is crucial for accurate medical coding, affecting reimbursement and preventing claim denials, while CPT codes establish the fundamental service being billed.
What are examples of a Modifier?
When a surgeon performs an extensive procedure that requires significantly more work than typically required, they might use modifier -22 (increased services) with the CPT code for that procedure to indicate the additional effort and potentially seek higher reimbursement.
If a patient receives an evaluation and management (E/M) service and also undergoes a minor procedure on the same day by the same physician, modifier -25 (significant, separately identifiable E/M service) would be appended to the E/M code to indicate that the E/M service was distinct from the procedure.
A physical therapist providing a distinct therapeutic service would use modifier -59 (distinct procedural service) to indicate that the service was separate and distinct from other services performed on the same day.
