CPT Modifier 25

Use CPT modifier ‘25' to report all significant, separately identifiable evaluation and management (E/M) visits by the same physician on the same day of a minor surgical procedure or other service. A minor procedure is defined as having a 0 or 10 day global time period. A physician may need to indicate that on the day he/she performed a minor procedure or service identified by a CPT code, the patient`s condition required a significant, separately identifiable E/M service beyond the other service provided or beyond the usual preoperative care associated with the procedure performed. In order to bill for the E/M service, all key components (history, examination, medical decision making) must be performed and supported by medical record documentation.

A modifier ‘25' is appropriate for the following situations:

Tetanus Vaccination
If a patient sustains an injury that requires a tetanus shot and an evaluation and management E/M service, attach modifier 25 to the E/M code. The claim should also include the date of injury and an accident diagnosis.

Chiropractic Manipulation and Modalities
When performing a significant, separately identifiable E/M service on the same day as a manipulation or modality providers must modify the E/M service with a modifier 25. Routine pre and post work included with a manipulation is not separately reportable as an E/M. A separate E/M is billable in cases where the patient presents with new or deteriorating clinical complaints that require a full review. At reasonable intervals, providers are required to reevaluate and assess positive findings or formulate a change plan, which typically requires an E/M service as well.

Preventive Medicine Codes
If, while performing a preventive medicine E/M service, you encounter a significant problem that requires additional work to perform the key components of an E/M service, you should also report the appropriate medical E/M code for that service, with the modifier 25 appended.
