Modifier 32 (Mandated Services) indicates that a CPT-coded service was required by a third party—such as an insurer, school, state agency, or court. The AMA defines it as denoting services mandated by third‑party requirements (for example, insurer‑required second opinions or school sports physicals). Append Modifier 32 to the applicable CPT code when the service itself was performed because of a mandate, and document the source of the mandate in the medical record or claim notes.

Using Modifier 32 signals the mandated nature of the service but does not dictate payment. The AMA guidance establishes the modifier’s purpose but does not guarantee reimbursement changes; actual payment treatment varies by payer. Before appending Modifier 32, verify the payer’s rules—some payers may require direct billing to the third party, have specific claim submission instructions, or apply different payment policies for mandated services. Failure to confirm payer policy can lead to denials or unexpected reimbursement outcomes.

Common scenarios for Modifier 32 include insurer‑required second opinions before surgery, school‑mandated sports or school physicals, evaluations ordered by state agencies or courts, and other third‑party mandates (employers, social services, or legal representatives). Examples: reporting 99383‑32 or 99393‑32 for a school‑required sports physical, or 99242‑32 for an insurer‑mandated independent surgical evaluation. Always check with the specific payer to determine whether the claim should be submitted on the practitioner’s CMS‑1500, billed directly to the third party, or handled under another procedure.
