CPT 01140: Anesthesia for Interpelviabdominal (Hindquarter) Amputation
CPT code 01140 represents anesthesia services for interpelviabdominal (hindquarter) amputation, a highly complex surgical procedure involving the removal of the lower limb and part of the pelvis. This code is significant for both clinical and billing purposes, as it ensures proper documentation and reimbursement for the specialized anesthesia care required during these operations. Nationally, the code is recognized by major payers including Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare, reflecting its broad applicability across diverse healthcare settings.
This publication provides a comprehensive overview of CPT 01140, including payer coverage, clinical context, and relevant policy updates. Readers will gain insight into typical sites of service, such as outpatient hospitals, and learn about common modifiers used in billing, as well as associated provider taxonomies. The analysis also highlights related CPT codes and ICD-10 diagnoses frequently encountered in cases requiring this anesthesia service. By understanding the nuances of CPT 01140, stakeholders can better navigate the complexities of medical billing, compliance, and clinical documentation for major amputation procedures.
CPT Code Overview
CPT 01140 is designated for anesthesia services provided during interpelviabdominal (hindquarter) amputation procedures. This code is used to report the administration of anesthesia for complex surgical interventions involving the removal of the lower limb and a portion of the pelvis. The service type is anesthesia, and the typical site of service is an outpatient hospital setting (POS 22). This code is critical for accurately capturing the resources and expertise required for such extensive surgical procedures.
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult patient presenting with severe, non-reconstructable pathology of the pelvis and lower extremity, such as advanced malignancy, chronic infection, or traumatic injury. The patient may have a history of conditions like unilateral primary osteoarthritis of the knee or chronic instability, leading to significant functional impairment. After multidisciplinary evaluation, the patient is scheduled for an interpelviabdominal (hindquarter) amputation in an outpatient hospital setting. Anesthesia services are provided throughout the procedure, ensuring patient safety and comfort during this extensive surgical intervention.
Coding Specifications
-
Modifiers:
-
QS: Monitored anesthesia care service. Used when anesthesia is provided in a manner that allows the patient to remain responsive and breathing independently, typically for procedures where full general anesthesia is not required. -
QX: CRNA service with medical direction by a physician. Used when a Certified Registered Nurse Anesthetist (CRNA) provides anesthesia care under the medical direction of a physician.

Related Diagnoses
-
M17.11: Unilateral primary osteoarthritis, right knee- Relevant for patients with severe degenerative changes in the right knee, potentially contributing to the need for amputation.
-
M17.12: Unilateral primary osteoarthritis, left knee- Indicates advanced osteoarthritis in the left knee, which may be a factor in surgical decision-making.
-
S83.241A: Sprain of medial collateral ligament of right knee, initial encounter- Represents acute injury to the right knee, possibly complicating the clinical scenario leading to amputation.
-
S83.242A: Sprain of medial collateral ligament of left knee, initial encounter- Denotes acute ligament injury in the left knee, which may be part of the patient's history.
-
M23.50: Chronic instability of knee, unspecified knee- Chronic instability can result in significant functional impairment, supporting the indication for major surgical intervention such as hindquarter amputation.
Related CPT Codes
| CPT Code | Description |
|---|---|
01150 | Anesthesia for radical procedures for tumor of pelvis, except hindquarter amputation |
01120 | Anesthesia for procedures on bony pelvis |
-
01150is used for anesthesia during radical pelvic tumor procedures that do not involve hindquarter amputation. It may be used as an alternative when the surgical approach differs. -
01120covers anesthesia for procedures on the bony pelvis, which may be performed in conjunction with or as a precursor to more extensive surgeries like hindquarter amputation. These codes are related by anatomical site and surgical complexity, and may be used together or as alternatives depending on the specific procedure performed.
