CPT Code Overview

CPT 01486 describes anesthesia services provided for open surgical procedures involving the bones of the lower leg, ankle, and foot when a more specific anatomic designation is not listed. The service is categorized under Anesthesiology and is typically delivered in the Inpatient Hospital (POS 21) setting.

Clinical Context

A 32-year-old healthy patient presents after an acute injury with a closed fracture of the upper end of the tibia. The patient is admitted to the inpatient hospital for open reduction and internal fixation of the tibial fracture under general or regional anesthesia. Preoperative evaluation in the preoperative holding area confirms American Society of Anesthesiologists (ASA) physical status P1. The anesthesiology team documents the planned anesthesia for an open procedure on the bones of the lower leg, ankle, or foot using code 01486. Intraoperative monitoring and anesthetic management are provided in the operating room; monitored anesthesia care may be documented with modifier QS when appropriate. Post-anesthesia care occurs in the hospital post-anesthesia care unit with routine recovery and postoperative pain management.

Coding Specifications

• Modifiers provided in the input and their use:

• QS: Monitored anesthesia care service. Use when monitored anesthesia care (MAC) is provided and documentation supports MAC as defined by anesthesiology standards.

• P1: A normal healthy patient. Use to indicate ASA physical status of a patient who is healthy without systemic disease.

• Associated provider taxonomies and specialty representation:

• 207L00000X: Anesthesiology — Physicians providing anesthetic care for perioperative management.

• 207LA0401X: Pain Medicine (Anesthesiology) — Anesthesiologists with a focus in pain medicine; may be involved in perioperative or postoperative analgesia planning.

• 207LP2900X: Pediatric Anesthesiology — Anesthesiologists specialized in anesthetic care for pediatric patients.

Related Diagnoses

• S82.101A — Fracture of upper end of right tibia, initial encounter for closed fracture

Clinical relevance: This fracture commonly requires open reduction and internal fixation or other open procedures on the lower leg bones, which would be addressed under anesthesia code 01486 when the procedure site is not otherwise specified.

• S82.102A — Fracture of upper end of left tibia, initial encounter for closed fracture

Clinical relevance: Same as above for the left tibial fracture; an open surgical approach on the lower leg would necessitate anesthesia coding such as 01486 if the site is described in nonspecific terms.

• M25.571 — Pain in right ankle and joints of right foot

Clinical relevance: Pain in the ankle/foot may be an indication for diagnostic or therapeutic open procedures on the lower leg/ankle/foot region; anesthesia for such procedures can be reported with 01486 when appropriate.

• M25.572 — Pain in left ankle and joints of left foot

Clinical relevance: Same relevance as M25.571 for the left side; may accompany or lead to operative interventions requiring anesthesia.

• S93.401A — Sprain of unspecified ligament of right ankle, initial encounter

Clinical relevance: A severe sprain with associated instability or associated injuries may lead to open surgical repair or exploration of ankle structures; anesthesia for such open procedures on the lower leg/ankle/foot may be reported with 01486 when documentation does not specify a more precise site-specific anesthesia code.

Related CPT Codes

• 01480 - Anesthesia for open procedures on bones of lower leg, ankle, and foot; tibia and fibula

This code covers anesthesia for open procedures specific to tibia and fibula. It is a more specific alternative when the procedure involves the tibia and fibula rather than the unspecified lower leg/ankle/foot site described by 01486.

• 01482 - Anesthesia for open procedures on bones of lower leg, ankle, and foot; ankle joint

This code applies when the open procedure is focused on the ankle joint. It may be selected instead of 01486 when documentation specifies ankle joint surgery.

• 01484 - Anesthesia for open procedures on bones of lower leg, ankle, and foot; foot

This code applies for open procedures confined to the foot. It is used as an alternative to 01486 when the operative site is explicitly the foot.

• 20680 - Removal of implant; deep (e.g., buried wire, pin, screw, metal band, nail, rod or plate)

This surgical code represents a procedure that may occur during the same operative encounter for which anesthesia is reported with 01486. 20680 may be performed as part of fracture management or hardware removal and is commonly billed in the same operative episode; anesthesia coding should reflect the actual procedure performed.

• Usage relationships:

• Codes 01480, 01482, and 01484 are site-specific anesthesia codes that can be used instead of 01486 when operative documentation identifies the tibia/fibula, ankle joint, or foot specifically.

• Code 20680 is a surgical procedure that may be performed during the anesthetic episode described by 01486. They are commonly associated in the clinical workflow when implant removal or deep hardware procedures accompany open lower leg/ankle/foot surgery.
