Summary & Overview

CPT 29819: Arthroscopic Removal of Loose or Foreign Body, Shoulder

CPT code 29819 represents arthroscopic removal of loose or foreign bodies from the shoulder joint. The procedure uses an arthroscope to locate and extract intra-articular debris—such as cartilage fragments, bone chips, or retained hardware—that cause pain, inflammation, adhesions, and restricted motion. This code is nationally relevant because shoulder arthroscopy is a common minimally invasive intervention that affects surgical caseloads, outpatient surgery utilization, and orthopedic service-line planning.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides clinicians, billing staff, and payers with a concise clinical description, expected site-of-service context, and the billing landscape relevant to this procedure.

Readers will learn the clinical context of CPT code 29819, operational considerations for arthroscopic shoulder work performed in operating rooms or ambulatory surgery centers, and what to expect in payer coverage patterns and coding practice. The summary also highlights common modifiers and administrative elements for downstream reference. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 29819 describes an arthroscopic procedure in which the provider inspects the interior of the shoulder joint with an arthroscope to identify and remove loose or foreign bodies. These loose or foreign bodies can include fragments of cartilage, bony debris, or retained surgical hardware such as suture anchors from prior procedures. The procedure addresses pain, inflammation, scar tissue, adhesions, and motion restriction caused by such intra-articular material.

Service type: Arthroscopic removal of loose or foreign bodies in the shoulder joint
Typical site of service: Operating room or ambulatory surgery center under arthroscopic technique

Clinical & Coding Specifications

Clinical Context

A 48-year-old patient presents with persistent anterolateral shoulder pain, mechanical catching, and limited range of motion after a prior rotator cuff repair performed 18 months earlier. Imaging (shoulder radiographs and MRI) demonstrates small intra-articular loose bodies and a retained suture anchor fragment within the glenohumeral joint. Conservative care including oral anti-inflammatory medications, physical therapy, and a corticosteroid injection provided partial relief but symptoms persist, affecting activities of daily living and sleep.

In the ambulatory surgical center or hospital outpatient operating room, the orthopedic surgeon performs a diagnostic and therapeutic arthroscopy of the shoulder under general anesthesia with regional block. Standard portals are established, the arthroscope is inserted to visualize the glenohumeral joint, and loose bodies and retained foreign material are identified and removed using graspers and a shaver. Hemostasis and joint inspection are completed, and portals are closed. Postoperative care includes brief recovery monitoring, discharge with physical therapy referral, and follow-up for range-of-motion progression and wound check.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when reporting only the surgeon's professional interpretation if separate technical component billed by facility or ASC applies.
`50`	Bilateral procedure	Use when arthroscopy and removal of loose bodies are performed on both shoulders during the same operative session.
`51`	Multiple procedures	Use when other distinct procedures are performed during the same operative session in addition to arthroscopic removal of loose bodies.
`52`	Reduced services	Use when the procedure is partially reduced or not completed as originally planned (e.g., aborted due to intraoperative findings).
`53`	Discontinued procedure	Use when the procedure is terminated before completion for patient-related or medical reasons.
`59`	Distinct procedural service	Use to indicate a separate and distinct procedure or service not normally reported together with another service.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons performing distinct portions of the procedure.
`78`	Unplanned return to OR by same physician following the initial procedure for a related procedure during the postoperative period	Use when the patient requires an unplanned reoperation for a complication related to this arthroscopy.
`80`	Assistant surgeon	Use when an assistant surgeon is present and performs part of the procedure.
`81`	Minimum assistant surgeon	Use when a minimal assistant is required and documented.
`82`	Assistant surgeon (when qualified resident surgeon not available)	Use when an assistant is needed but a qualified resident is unavailable.
`LT`	Left side	Use to indicate the procedure was performed on the left shoulder.
`RT`	Right side	Use to indicate the procedure was performed on the right shoulder.
`TC`	Technical component	Use when reporting only the facility/technical component separate from the surgeon's professional service.
