The code for the second procedure would have the -59 modifier appended to it, indicating that it is a separate and distinct procedure from the first one.
In medical coding, modifiers are used to provide additional information about a procedure or service provided to the patient.
In the scenario you described, two procedures were performed during the same operative session: a distal first metatarsal cheilectomy and correction of a hammertoe on the third toe.
When multiple procedures are performed during the same session, it is important to indicate this appropriately using modifiers.
In this case, the modifier that would be assigned for the second procedure (correction of hammertoe on the third toe) is "-59."
The modifier -59 is used to indicate that a procedure is distinct or independent from other non-evaluation and management (E/M) services performed on the same day.
So, the code for the second procedure would have the -59 modifier appended to it, indicating that it is a separate and distinct procedure from the first one.
Always follow the specific coding guidelines and rules of the relevant coding system (e.g., Current Procedural Terminology (CPT) codes) when applying modifiers.
