Summary & Overview
CPT 01340: Anesthesia for Closed Procedures on Lower Third of Femur
CPT 01340 identifies anesthesia services for closed procedures on the lower one‑third of the femur. It specifies the anesthesia component tied to distal femoral interventions performed via closed techniques and is used by anesthesia professionals to report perioperative care for these surgical procedures. Nationally, precise CPT coding for procedure‑specific anesthesia ensures consistent clinical documentation, billing clarity, and supports appropriate care coordination for orthopedic surgical services.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare. Readers will gain a concise understanding of the clinical context for CPT 01340, common billing relationships to related anesthesia and orthopedic procedure codes, and the payer landscape relevant to anesthesia services for distal femur closed procedures. The publication summarizes coding definitions, service settings where the code is typically used, and how this code relates to other anesthesia codes for femoral procedures.
This summary is intended for clinicians, coding professionals, and policy analysts seeking a clear reference on what CPT 01340 represents, where it is applied, and which major national payers commonly cover services billed with this code. Data not available in the input will be noted in the detailed sections of the full publication.
CPT Code Overview
CPT 01340 covers anesthesia services provided for all closed procedures on the lower one‑third of the femur. This code represents the anesthesia care associated with surgical interventions that are performed through closed techniques on the distal femur.
Service Type: Anesthesia
Typical Site of Service: Surgical/procedure setting (for example, Hospital Operating Room, POS 22 or Ambulatory Surgery Center, POS 24)

Clinical & Coding Specifications
Clinical Context
A middle-aged patient presents for surgical management of a distal femoral procedure performed through closed techniques (for example, closed reduction of a distal femoral fracture or manipulation for intra‑articular derangement) under anesthesia targeted to the lower one‑third of the femur. The patient is evaluated preoperatively in the pre‑anesthesia clinic or on the day of surgery, with review of history, physical exam, airway assessment, and medication reconciliation. In the operating room or ambulatory surgery center, the anesthesia team provides monitored care or general/regional anesthesia as indicated for the targeted closed procedure on the lower third of the femur. The workflow includes induction, maintenance, surgical procedure, emergence, and handoff to post‑anesthesia care unit staff for recovery and postoperative pain management planning.

Modifiers
-
QS: Monitored anesthesia care (MAC) service. Use when the anesthesia service provided meets MAC definition and is reported for the procedure covered by the anesthesia code. -
QX: CRNA service with medical direction by a physician. Use when a Certified Registered Nurse Anesthetist (CRNA) furnishes the anesthesia service and a physician provides medical direction meeting applicable supervision requirements. -

Related Diagnoses
-
M17.11— Unilateral primary osteoarthritis, right kneeClinical relevance: Osteoarthritis of the right knee may contribute to pain, limited function, or need for interventions involving the distal femur and peri‑articular structures relevant to anesthesia for lower femur procedures.
-
M23.50— Chronic instability of knee, unspecified kneeClinical relevance: Chronic knee instability can be associated with procedures addressing femoral fixation or manipulations; anesthesia targeting the lower one‑third of the femur may be used during corrective closed procedures.
-
S83.241A— Other tear of medial meniscus, current injury, right knee, initial encounterClinical relevance: A current medial meniscus tear of the right knee may require closed procedures or arthroscopic interventions involving the distal femur region; anesthesia for the lower femur would be appropriate for such closed procedures.
-
M25.561— Pain in right kneeClinical relevance: Knee pain is a common symptom prompting diagnostic or therapeutic closed procedures on the lower femur; anesthesia services coded with
01340may be furnished for interventions addressing pain generators. -
S83.511A— Sprain of anterior cruciate ligament of right knee, initial encounterClinical relevance: Acute ACL sprain may lead to closed reduction or manipulative procedures in the distal femur/knee region; anesthesia for the lower one‑third of femur can be provided for such closed interventions.

| CPT Code | Description |
|---|---|
01360 | Anesthesia for all open procedures on lower one‑third of femur |
01360 represents anesthesia services for open procedures on the lower one‑third of the femur and is a related code to 01340, which covers closed procedures on the same anatomic region. In clinical workflow, 01340 is assigned when the surgeon performs closed management (no open exposure), while 01360 is assigned when the surgical approach is open. These codes are alternatives based on the surgical technique; they are not typically reported together for the same surgical encounter.
