What requirement leads to the application of modifier 32?

Modifier 32 is used when a consultation is mandated, often at the request of a third party, such as an insurer or a governmental agency. This modifier indicates that the physician's services were provided as a result of a specific requirement for a consultation that is necessary to support a patient's medical care.

When a consultation is mandated, it often involves specific circumstances where the requesting party requires documentation of a physician's opinion or evaluation on a patient's condition. This could include situations such as worker's compensation claims or disability determinations, where an outside entity requires validation of the patient's needs from a specialist.

The other options do not correctly represent the requirement for applying modifier 32. A voluntary consultation request does not satisfy the criteria for this modifier, as it is not initiated by a mandated request from a third party. Elective surgery scheduling and routine follow-ups also do not involve the compelled nature of referrals that characterize situations requiring modifier 32. Thus, the correct application of this modifier aligns with the requirements that stem from mandated consultations.
