Modifier 47 is used when the surgeon personally administers regional or general anesthesia while also performing the surgical procedure.

What is Modifier 47?

Modifier 47 identifies circumstances in which the surgeon performing a procedure also personally administers the regional or general anesthesia required for that procedure. It distinguishes surgeon-administered anesthesia from anesthesia services provided separately by an anesthesiologist, certified registered nurse anesthetist, or other anesthesia professional.

The modifier is appended to the surgical procedure code, not an anesthesia code. It communicates that anesthesia was administered by the surgeon as part of the operative service.

Modifier 47 should only be used when the surgeon personally administers qualifying regional or general anesthesia. Local anesthesia administered by the surgeon is generally considered part of the surgical procedure and does not support Modifier 47.

When to Use Modifier 47

Surgeon Personally Administers Anesthesia: The physician performing the surgery personally provides the qualifying anesthesia rather than having a separate anesthesia professional provide the service.

Regional Anesthesia: Modifier 47 may be appropriate when the surgeon administers qualifying regional anesthesia in connection with the procedure.

General Anesthesia: Surgeon-administered general anesthesia may support Modifier 47 when all applicable coding and payer requirements are satisfied.

Eligible Surgical Procedure: The underlying procedure and circumstances must support use of the modifier under applicable coding and payer rules.

Documentation Supports Both Services: The operative and anesthesia documentation should clearly establish that the operating surgeon personally administered the anesthesia.

When NOT to Use Modifier 47

Local Anesthesia: Do not report Modifier 47 merely because the surgeon administers local anesthesia. Local infiltration is generally considered inherent to the surgical procedure.

Separate Anesthesia Professional: Modifier 47 is not appropriate when an anesthesiologist, CRNA, or another anesthesia professional administers the anesthesia.

Anesthesia Procedure Codes: Modifier 47 is appended to the surgical procedure code rather than separately reported on an anesthesia code to represent the surgeon's anesthesia service.

Routine Sedation: Do not assume that sedation administered during a procedure automatically qualifies. The anesthesia provided must meet the requirements for reporting Modifier 47.

Billing Example

A surgeon performs an eligible operative procedure and personally administers regional anesthesia to the patient rather than using a separate anesthesia professional.

The surgeon reports the appropriate surgical procedure code with Modifier 47 to indicate that the anesthesia was personally administered by the operating surgeon.

The medical record should clearly identify the anesthesia technique, the individual who administered it, and the surgical service performed.

Documentation Requirements

Anesthesia Provider: Clearly document that the operating surgeon personally administered the anesthesia.

Type of Anesthesia: Identify whether regional or general anesthesia was administered and describe the technique when appropriate.

Surgical Procedure: Maintain complete operative documentation supporting the underlying surgical procedure.

Anesthesia Record: Document relevant anesthesia information, including administration, patient monitoring, and other required clinical details.

Patient Response: Record relevant patient status and response to the anesthesia throughout the procedure.

Medical Necessity: Documentation should support why the anesthesia and underlying surgical procedure were medically appropriate.

Billing and Claim Considerations

Modifier 47 should be appended to the applicable surgical procedure code when the operating surgeon personally administers qualifying anesthesia. It should not be used to create a separate anesthesia service when the circumstances do not support separate reporting.

Providers should verify payer policies because reimbursement treatment can vary. The presence of Modifier 47 does not guarantee additional payment for the surgeon-administered anesthesia.

The modifier also should not be confused with anesthesia modifiers such as AA, QK, QX, QY, or QZ. Those modifiers generally communicate information about anesthesia professionals, medical direction, or anesthesia service arrangements rather than anesthesia personally administered by the operating surgeon.

Common Billing Mistakes

Reporting Modifier 47 for Local Anesthesia: Local anesthesia provided by the surgeon is generally included in the surgical service and does not justify Modifier 47.

Appending Modifier 47 to an Anesthesia Code: Modifier 47 identifies anesthesia administered by the surgeon and should be appended to the surgical procedure code when appropriate.

Using Modifier 47 When Another Provider Administers Anesthesia: The modifier does not apply when anesthesia is furnished by a separate anesthesiologist, CRNA, or other anesthesia professional.

Assuming All Surgeon-Administered Sedation Qualifies: Not every form of sedation meets the requirements for Modifier 47. The type of anesthesia and applicable coding rules must support its use.

Insufficient Anesthesia Documentation: Reporting the modifier without clearly documenting who administered the anesthesia and what type was provided can result in claim problems.

Assuming Additional Payment Is Automatic: Modifier 47 communicates the circumstances of the service but does not guarantee increased or separate reimbursement.

Common Denial Reasons

Anesthesia Type Does Not Qualify: Documentation indicates only local anesthesia or another anesthesia service that does not support Modifier 47.

Separate Anesthesia Provider Documented: The medical record shows that someone other than the operating surgeon administered the anesthesia.

Modifier Applied to the Wrong Code: Modifier 47 is reported incorrectly on an anesthesia code or another service that does not support its use.

Documentation Does Not Identify the Anesthesia Provider: The medical record fails to establish that the surgeon personally administered the anesthesia.

Incomplete Anesthesia Documentation: Records do not adequately describe the anesthesia technique, administration, monitoring, or other information required by the payer.

Payer Requirements Were Not Met: The payer does not recognize the modifier for the reported circumstances or requires additional documentation before considering the claim.

Modifier 47 vs. Separate Anesthesia Services

Modifier 47 is specifically intended to identify qualifying anesthesia personally administered by the surgeon performing the procedure. It does not describe anesthesia furnished independently by a separate anesthesia professional.

When an anesthesiologist, CRNA, or another qualified anesthesia professional provides the anesthesia service, the appropriate anesthesia procedure code and applicable anesthesia modifiers are generally used instead. The provider arrangement documented in the medical record therefore determines whether Modifier 47 is appropriate.
