Modifier 82- Assistant Surgeon (When Qualified Resident Surgeon Not Available)

Modifier 82 is used when a physician serves as an assistant surgeon because a qualified resident surgeon is not available in a teaching hospital.

What is Modifier 82?

Modifier 82 identifies assistant surgeon services performed by a physician in a teaching hospital when a qualified resident surgeon is unavailable. The modifier allows the assistant surgeon to report medically necessary assistance when the teaching hospital cannot provide an appropriate resident for the procedure. Documentation should clearly support the unavailability of a qualified resident and comply with payer requirements.

When to Use Modifier 82

• The procedure is performed in a teaching hospital.

• A qualified resident surgeon is not available.

• A physician provides medically necessary assistant surgeon services.

• Documentation supports the resident's unavailability.

Billing Example

A cardiovascular surgeon performs a complex bypass procedure at a teaching hospital. Because no qualified resident surgeon is available, another physician assists throughout the operation and reports the procedure using Modifier 82.

Documentation Tips

• Document that the procedure occurred in a teaching hospital.

• State that no qualified resident surgeon was available.

• Identify the assistant surgeon in the operative report.

• Verify payer requirements before submitting the claim.

Common Denial Reasons

• Documentation does not support the resident's unavailability.

• The procedure was not performed in a teaching hospital.

• Medical necessity for an assistant surgeon is not established.

• Modifier 82 is reported for an ineligible procedure.
