CPT 01382: Anesthesia for Diagnostic Arthroscopic Procedure of Knee Joint
CPT code 01382 identifies anesthesia services furnished for diagnostic arthroscopic procedures of the knee joint. Anesthesia coding for arthroscopic knee diagnostics is important nationwide because it standardizes billing for perioperative anesthetic management in a common orthopedic outpatient and inpatient procedure. Accurate use of this anesthesia code affects claim adjudication, provider reimbursement, and resource reporting across surgical settings.
Key payers referenced include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for anesthesia during knee arthroscopy, how this code relates to closely associated knee anesthesia codes, typical sites of service, and payer coverage considerations. The publication also outlines common procedural contexts and ICD-10 diagnoses that commonly justify use of this code, and highlights related anesthesia codes used for other knee procedures.
This summary serves clinicians, billing professionals, and policy analysts seeking a national perspective on coding for anesthesia during diagnostic knee arthroscopy, with practical information on code purpose, clinical setting, and payers commonly involved in claims processing.

Billing Code Overview
CPT code 01382 describes anesthesia services provided for a patient undergoing a diagnostic arthroscopic procedure of the knee joint. This service is the administration and management of anesthesia care during a minimally invasive diagnostic arthroscopy of the knee.
-
Service type: Anesthesia for diagnostic arthroscopic knee procedure
-
Typical site of service: Ambulatory surgical center or hospital operating room
Clinical & Coding Specifications
Clinical Context
A 52-year-old active patient presents with progressive right knee pain, intermittent instability, and mechanical catching despite conservative measures. Imaging (MRI) demonstrates a meniscal tear with early degenerative changes and focal chondral wear. The orthopedic surgeon schedules a diagnostic and therapeutic arthroscopic knee procedure (arthroscopy with possible partial meniscectomy or chondroplasty). The anesthesiology team provides anesthesia services coded as 01382 for a diagnostic arthroscopic procedure of the knee joint. Typical workflow: preoperative evaluation by the anesthesiologist (medical history, airway assessment, anesthesia risk classification), selection of anesthetic technique (general endotracheal anesthesia or monitored anesthesia care with regional block), intraoperative anesthesia management during arthroscopy, postoperative handoff to PACU with analgesia plan. Typical site of service is an outpatient ambulatory surgery center or hospital operating room.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Unusual procedural services | When the anesthesia service required substantially greater effort or time than typical for 01382 and documentation supports increased complexity. |
23 | Unusual anesthesia | When general anesthesia is medically necessary for a procedure normally performed with local/monitored anesthesia and documentation supports the medical necessity. |
50 | Bilateral procedure | When identical arthroscopic procedures are performed on both knees during the same anesthetic episode. |
52 | Reduced services | When the planned arthroscopic diagnostic procedure is partially reduced or not completed but some anesthesia was provided. |
53 | Discontinued procedure | When the procedure is started but terminated due to extenuating circumstances and anesthesia was provided up to termination. |
54 | Surgical care only | When the anesthesiologist only provided intraoperative anesthesia services and pre/postoperative anesthesia responsibility is transferred to another provider. |
55 | Postoperative management only | When the anesthesiologist provides only postoperative pain management and does not participate in intraoperative anesthetic care. |
56 | Preoperative management only | When the anesthesiologist provides only preoperative evaluation and preparation and does not provide intraoperative services. |
62 | Two surgeons | When two surgeons of different specialties participate and require independent anesthesia considerations influencing anesthetic plan. |
78 | Unplanned return to the operating room for a related procedure during the global period | When a patient returns to the OR for a complication related to the initial arthroscopy and requires additional anesthesia. |
AA | Anesthesiologist service performed personally | When the service was personally performed by a physician anesthesiologist. |
AD | Medical supervision by a physician; more than four concurrent anesthesia procedures | When the physician supervises multiple concurrent cases and provides required supervisory documentation. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist service for anesthesia | When a qualified non-physician anesthesia provider furnishes the anesthesia service under appropriate supervision. |
QK | Medical direction of two, three, or four concurrent anesthesia procedures involving qualified individuals | When the physician medically directs multiple concurrent anesthesia procedures meeting CMS criteria. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Physicians who provide perioperative anesthesia care, typical primary taxonomy for 01382. |
207LA0401X | Pain Medicine Anesthesiologist | Anesthesiologists with subspecialty in pain medicine who may manage perioperative regional analgesia techniques. |
207RA0401X | Pain Medicine Physician | Physicians specializing in pain who may be involved in complex analgesia planning or postoperative pain management. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
M23.50 | Chronic instability of knee, unspecified knee | Chronic knee instability is an indication for diagnostic arthroscopy to assess ligaments, menisci, and articular surfaces. |
M25.561 | Pain in right knee | Localized right knee pain is a common presenting symptom prompting diagnostic arthroscopy when conservative care fails. |
M25.562 | Pain in left knee | Localized left knee pain is a common presenting symptom prompting diagnostic arthroscopy when conservative care fails. |
M17.11 | Unilateral primary osteoarthritis, right knee | Osteoarthritic changes may require arthroscopic evaluation and debridement or assessment prior to definitive knee arthroplasty planning. |
M17.12 | Unilateral primary osteoarthritis, left knee | Osteoarthritic changes may require arthroscopic evaluation and debridement or assessment prior to definitive knee arthroplasty planning. |
