HCPCS J7318: Durolane, Intra-articular Hyaluronan Injection, 1 mg
HCPCS Level II code J7318 identifies Durolane, a hyaluronan derivative, billed per 1 mg for intra-articular injection. The code is used to report viscosupplementation procedures intended to relieve joint pain through intra-articular administration of a single-dose hyaluronan product. Nationally, use of this code reflects utilization of non-opioid, procedure-based management for osteoarthritis and other joint conditions, with implications for outpatient practice workflows, payer coverage policies, and supply-chain considerations.
Key payers in this national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for viscosupplementation, common sites of service where J7318 is billed, and an outline of the billing and coding considerations relevant to this HCPCS Level II code. The publication also covers benchmarking and reimbursement context where available, recent policy developments that affect coverage and prior authorization, and practical notes on documentation requirements tied to intra-articular injection services.
This summary is intended to help billing managers, clinicians, and policy analysts quickly understand the role of HCPCS Level II code J7318 in outpatient musculoskeletal care and payer interactions. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is a middle-aged to older adult with symptomatic osteoarthritis of a synovial joint (most commonly the knee) presenting with chronic joint pain, stiffness, and impaired function despite conservative care (NSAIDs, physical therapy, weight management). The clinical workflow includes: history and focused musculoskeletal exam confirming osteoarthritic symptoms; imaging review (recent radiographs or MRI if available) to assess joint space narrowing and exclude alternative pathology; discussion of intra-articular hyaluronan therapy (viscosupplementation) including expected benefits and risks; informed consent documentation; verification of no active infection or anticoagulation contraindication; preparation of a sterile field in an outpatient clinic or ambulatory surgical center; aspiration of effusion if present; administration of J7318 (durolane hyaluronan) into the affected joint with appropriate needle and technique; post-injection monitoring for immediate adverse reaction; and documentation of product lot number, units administered, and site of injection. Typical sites of service are outpatient office-based procedure rooms, ambulatory surgery centers, and orthopedic or sports medicine clinics. Common patient scenario: a 62-year-old patient with knee osteoarthritis (chronic pain limiting ambulation) who has failed conservative therapy and elects for a single-injection hyaluronan product to improve pain and function.
