CPT 01622: Anesthesia for Diagnostic Shoulder Arthroscopy

CPT code 01622 designates anesthesia services for a diagnostic arthroscopic procedure of the shoulder joint. This code captures the anesthetic management associated with shoulder diagnostic arthroscopy and is relevant to anesthesiologists, certified registered nurse anesthetists, surgical teams, and billing professionals. Nationally, accurate use of this code affects procedural coding consistency, payer adjudication, and quality reporting for perioperative services.

Major national payers included in the review are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and billing context for CPT code 01622, including typical sites of service and associated clinical scenarios. The publication outlines common diagnostic procedures to which the code applies and situates the code within broader anesthesia service documentation and coding practices.

The report provides benchmarks and comparative references to related surgical arthroscopy codes to clarify clinical relationships and coding pathways. It also highlights policy considerations relevant to anesthesia coding for diagnostic arthroscopy at the national level, and summarizes what clinicians and coding professionals need to know when documenting anesthetic services for shoulder arthroscopy.

Billing Code Overview

CPT code 01622 describes anesthesia services provided for a diagnostic arthroscopic procedure of the shoulder joint. The service type is anesthesia for diagnostic shoulder arthroscopy, typically delivered in an ambulatory surgery center or hospital outpatient/inpatient surgical setting. The code covers perioperative anesthetic management associated with the diagnostic arthroscopy of the shoulder.

Clinical & Coding Specifications

Clinical Context

A 52-year-old active patient presents with several months of progressive right shoulder pain, mechanical catching, and reduced range of motion despite conservative management including physical therapy and NSAIDs. Imaging (MRI) suggests an intra-articular tear amenable to diagnostic arthroscopy. The patient is scheduled for a diagnostic shoulder arthroscopic procedure under monitored anesthesia care (MAC) with possible conversion to general endotracheal anesthesia if surgical intervention is required. Preoperative evaluation by the anesthesia team documents ASA physical status P2, airway assessment, and relevant comorbidities. On the day of service the anesthesiology professional obtains informed consent for anesthesia, induces and maintains appropriate sedation/analgesia, monitors hemodynamics, and provides perioperative airway management. Intraoperatively, the anesthetist adjusts anesthetic depth for patient comfort and surgical requirements, communicates with the surgeon about positioning and fluid management, and documents intraoperative events and any complications. Postoperative handoff includes recovery instructions, pain control plan, and disposition to PACU. Typical sites of service are an ambulatory surgery center or hospital outpatient surgery suite equipped for arthroscopic orthopedic procedures.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when anesthesia care involves substantially greater intensity (e.g., unusually difficult airway or prolonged unexpected complexity) beyond typical for a diagnostic shoulder arthroscopy.
`23`	Unusual anesthesia	Use when general anesthesia is required for a procedure that is usually performed with regional/local anesthesia, if applicable to the case.
`50`	Bilateral procedure	Use when identical bilateral shoulder procedures are performed during the same operative session and anesthesia is provided for both.
`52`	Reduced services	Use when the planned procedure is partially reduced or not completed but anesthesia was delivered (e.g., procedure abbreviated due to intraoperative findings).
`53`	Discontinued procedure	Use when the procedure is terminated due to patient condition or surgical decision and full anesthesia was not completed as planned.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons for a complex shoulder procedure requiring combined expertise and anesthesia documentation supports this.
`78`	Return to OR for related procedure during postoperative global period	Use when the patient returns to the operating room for a related shoulder procedure and additional anesthesia is provided during the global period.
`AA`	Anesthesia services performed personally by anesthesiologist	Use when an anesthesiologist personally performs the anesthesia services for the case.
`AD`	Medical supervision by physician; more than four concurrent anesthesia procedures	Use when supervising physician oversees more than four concurrent anesthesia procedures and documents supervisory activity.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist services for anesthesia	Use when a physician assistant, nurse practitioner, or clinical nurse specialist conducts the anesthesia service as allowed by state law and payer rules.
`QK`	Medical direction of two, three, or four concurrent anesthesia procedures involving qualified individuals	Use when the anesthesiologist medically directs multiple CRNAs/assistants for concurrent anesthesia services.
`QS`	Monitored anesthesia care (MAC) service	Use to indicate monitored anesthesia care was provided for the diagnostic arthroscopy when payor requires this modifier for MAC reporting.
`QX`	CRNA service furnished under supervision of an anesthesiologist (distinct from QY/QX pairings)	Use when a Certified Registered Nurse Anesthetist (CRNA) furnishes anesthesia under an anesthesiologist's supervision according to payer rules.

Taxonomy Code	Specialty	Notes
`207L00000X`	Anesthesiology	Physician anesthesiologists who personally provide or supervise anesthesia services for shoulder arthroscopy.
`367500000X`	Certified Registered Nurse Anesthetist	CRNAs who provide MAC or general anesthesia for arthroscopic shoulder procedures, often in ambulatory settings.
`207RA0401X`	Anesthesiology Assistant	Anesthesiology assistants who deliver anesthesia under physician supervision in applicable states and facilities.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance

`M17.12`	Unilateral primary osteoarthritis, left knee	Same clinical relevance as `M17.11` for the contralateral knee; included in the provided list.
`S83.241A`	Other tear of lateral meniscus, current injury, right knee, initial encounter	Acute meniscal tear diagnosis that commonly leads to arthroscopic diagnostic and therapeutic procedures; anesthesia is provided for these interventions.
`S83.242A`	Other tear of lateral meniscus, current injury, left knee, initial encounter	Contralateral acute meniscal tear; relevant to arthroscopic evaluation and management requiring anesthesia.
