Musculoskeletal System / General section (codes 20005-20999)

Why This Topic Matters

Musculoskeletal coding often depends on procedure type, anatomy, site specificity, documentation, and payer policy. Understanding this general-section guidance can help reduce denials, support medical necessity, and improve code selection consistency.
