Medical Coding Chapter 15 Review (80+ Q&A) – Fractures, Arthroscopy, Grafts, CPT Musculoskeletal | 2025/2026

This detailed review includes over 80 expert-verified questions and CPT-based answers aligned with Chapter 15 of the 2025/2026 Medical Coding curriculum, focused on Musculoskeletal System procedures within the CPT coding system. It covers orthopedic surgeries, joint procedures, fracture treatments, surgical approaches, instrumentation, and grafts, offering real-world coding insight for both educational and clinical application. Key topics covered: Wound exploration and debridement: CPT codes 20100–20103, bundled services, coding rules based on wound enlargement and complexity Fracture care: Open vs. closed treatment, manipulation (reduction), traction types (skin, skeletal), casting/strapping inclusion, and ORIF procedures Arthroscopy procedures: Diagnostic vs. surgical scopes (e.g., CPT 29827, 29882), shoulder and knee repairs, benefits (faster recovery, smaller incisions), and bundled diagnostic scopes Bone and tissue grafts: Fascia lata, tendon, cartilage, and bone graft types, including CPT coding logic and use of modifiers Joint procedures: Arthrocentesis (CPT 20600–20611), aspiration, injections, and site-specific codes Orthopedic surgeries: Total hip (27130), total knee (27447), rotator cuff repair (29827), and more Dislocation treatments: Closed and open dislocation management, CPT codes by site and method (e.g., 27265 for hip dislocation without anesthesia) Complex coding examples: Ganglion cyst injection (20612), halo removal (99024), scar revision after amputation (25907-RT), multiple digit/metatarsal fractures (28510, 28475 variations) Muscle pressure monitoring & segmental instrumentation: Interstitial fluid pressure devices and CPT rules for spinal repairs This guide is best for: Medical coding students preparing for CPT-focused exams (CPC, CCS) Orthopedic coding professionals and outpatient surgical coders HIM and HIT students specializing in procedural documentation Instructors building musculoskeletal-focused assessments Keywords: CPT musculoskeletal, fracture treatment coding, open vs closed reduction, arthroscopy CPT, joint aspiration, arthrocentesis, rotator cuff repair, hip replacement CPT, bone grafts, tendon grafts, traction, halo removal, ganglion cyst injection, spinal instrumentation, orthopedic coding, surgical coding
