Summary & Overview

CPT 29863: Arthroscopic Hip Synovectomy

CPT code 29863 represents arthroscopic hip synovectomy — a minimally invasive surgical procedure to inspect the hip joint with an arthroscope and excise inflamed synovial tissue that produces pain and restricts motion. Nationally, this code is used to classify operative hip arthroscopy services tied to diagnosis-driven management of intra-articular synovitis and related mechanical symptoms. It matters because arthroscopic hip procedures have grown in clinical use for younger, active patients and can affect surgical utilization, prior authorization practices, and post-acute care pathways.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and site-of-service patterns, typical payer coverage considerations, common administrative modifiers (reference only), and benchmarks for utilization where available. The report also outlines policy and coding considerations relevant to billing and claims adjudication for hip arthroscopy.

This publication is intended for coding professionals, surgical providers, revenue cycle managers, and policy analysts seeking a clear, national-level summary of the clinical meaning, billing context, and payer landscape for CPT code 29863.

Billing Code Overview

CPT code 29863 describes an arthroscopic procedure of the hip joint in which the provider inspects and repairs the synovial membrane and related intra-articular structures. The procedure involves insertion of an arthroscope and instruments to visualize the inside of the hip joint and excise inflamed synovial tissue causing pain and limited motion.

Service type: Arthroscopic synovectomy / hip joint arthroscopy
Typical site of service: Ambulatory surgical center or hospital outpatient department (operative setting for hip arthroscopy)

Clinical & Coding Specifications

Clinical Context

A 42-year-old patient presents with progressive groin pain, mechanical catching, and limited internal rotation of the hip after months of activity-related symptoms. Conservative management including physical therapy, NSAIDs, and activity modification provided incomplete relief. Imaging (MRI arthrogram) demonstrates focal synovial hypertrophy and labral irritation without advanced osteoarthritis. The orthopedic surgeon schedules an arthroscopic hip procedure to inspect the intra-articular structures, perform synovectomy, and address any concomitant pathologic findings.

The clinical workflow includes preoperative evaluation with history and focused exam, preoperative imaging review, informed consent, anesthesia evaluation (typically general or regional), and operating room arthroscopy. Intraoperatively the surgeon introduces an arthroscope into the hip joint, performs diagnostic inspection, and uses arthroscopic instruments to excise inflamed synovial tissue (synovectomy). The procedure may include lavage, hemostasis, and concurrent treatment of labral tears or chondral lesions if present. Postoperative workflow includes PACU recovery, postoperative pain control, wound instructions, weight-bearing and physical therapy recommendations, and follow-up clinic visits for range-of-motion assessment and progression of rehabilitation.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when work, time, or complexity substantially exceeds typical for `29863`. Documentation must support increased work.
`52`	Reduced services	Use when the procedure was partially completed or limited for clinical reasons.
`53`	Discontinued procedure	Use when the procedure was terminated due to extenuating circumstances prior to completion.
`59`	Distinct procedural service	Use to indicate a separate, distinct procedure when multiple services are reported for the same patient on the same date.
`62`	Two surgeons	Use when two surgeons with different specialties perform distinct elements of the procedure concurrently.
`76`	Repeat procedure by same physician	Data not available in the input.
`78`	Unplanned return to the operating room for a related procedure during the postoperative global period	Use when patient returns to OR for a complication related to the initial `29863` during the global period.
`80`	Assistant surgeon	Use when a surgical assistant participates in the procedure.
`81`	Minimum assistant surgeon	Use when an assistant provides minimal assistance.
`TC`	Technical component	Use when billing only the technical component (facility resources) if applicable in split-billing arrangements.

Taxonomy Code	Specialty	Notes
207L00000X	Orthopaedic Surgery	Primary specialty performing hip arthroscopy and synovectomy.
207T00000X	Sports Medicine (Orthopaedic)	Common subspecialty managing intra-articular hip pathology in active patients.
2086S0127X	Physical Medicine & Rehabilitation	May co-manage perioperative rehabilitation and postoperative functional recovery.
207RH0000X	Adult Reconstructive Orthopedics	May be involved when concurrent degenerative changes require reconstruction.
