Summary & Overview
HCPCS Level II S2112: Knee Arthroscopy for Cartilage Harvest
HCPCS Level II code S2112 identifies an arthroscopic surgical procedure of the knee performed specifically to harvest cartilage (chondrocyte cells). This code is relevant nationally as interest in cartilage repair and cell-based therapies grows and as payers refine coverage policies for biologic and regenerative interventions. The procedure is typically performed in ambulatory surgical centers or hospital operating rooms and is distinct from diagnostic or purely therapeutic arthroscopy codes because its primary purpose is tissue procurement for downstream regenerative treatment.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context and operative intent, common modifier usage and billing considerations (where available), and how this service aligns with broader trends in orthopedic regenerative care. The publication outlines benchmarks and policy-relevant points such as payer coverage variability, coding specificity for cartilage harvest versus other knee arthroscopy procedures, and the implications for claims processing and documentation. Data not available in the input include associated taxonomies, specific ICD-10 diagnosis pairings, and related codes.
Billing Code Overview
HCPCS Level II code S2112 describes arthroscopy of the knee performed to harvest cartilage (chondrocyte cells). The procedure involves surgically obtaining cartilage tissue from the knee joint for downstream use in cartilage repair or regenerative therapies.

Clinical & Coding Specifications
Clinical Context
A 32-year-old active male presents with persistent focal chondral defect of the medial femoral condyle after a failed conservative course including physical therapy and intra-articular injections. Imaging with MRI confirms an isolated full-thickness cartilage lesion approximately 2.0–2.5 cm2. The orthopedic surgeon schedules an outpatient arthroscopic procedure to harvest autologous cartilage for chondrocyte culture and later implantation. The patient arrives to an ambulatory surgery center (ASC) on the day of surgery; preoperative evaluation documents no active infection and acceptable medical clearance. Under general or regional anesthesia, standard diagnostic knee arthroscopy is performed for joint assessment. Using arthroscopic instruments, healthy-appearing cartilage is harvested from a non–weight-bearing area of the femoral trochlea or intercondylar notch. Harvest sites are documented, specimens are sent to the tissue-processing facility, and portals are closed. The patient recovers in PACU with standard postoperative instructions and a staged plan for cultured chondrocyte implantation. Billing reflects arthroscopic cartilage harvest using code S2112 with appropriate modifiers documenting site laterality, place of service, and any unusual circumstances (for example, increased procedural complexity).
