Fibroblastic proliferation of the palmar fascia causing nodule formation, cord development, and progressive flexion contracture of one or more fingers — the defining features of Dupuytren's disease.

Documentation tips

What should appear in the chart to support M72.0.

Source · Editorial brief grounded in 5 cited references ↓

• Document laterality by name (right, left, or bilateral) — M72.0 has no laterality subcode, but payers and operative reports require the affected hand(s) to be named explicitly.
• Record which rays are involved (e.g., ring and small finger cords) to support procedure-level coding — CPT fasciectomy codes differentiate by number of digits.
• Note the type of pathology present: palmar nodule only, pretendinous cord, or fixed flexion contracture with degree of contracture (e.g., ≥20° at MCP or PIP) to support medical necessity for intervention.
• Document conservative measures attempted (splinting, physical therapy, observation period) before procedural authorization, especially for collagenase injection (26341) or fasciectomy.
• If bilateral disease is present, document both hands explicitly in the assessment — a single M72.0 covers bilateral, but payers may request side-specific operative documentation.

Common coding pitfalls

The recurring mistakes coders make with M72.0 and adjacent codes.

Source · Editorial brief grounded in CDC ICD-10-CM tabular guidance, AAOS coding references, and cited references ↓

• Assigning M72.1 (knuckle pads) instead of M72.0 when dorsal PIP thickening co-exists with palmar cords — knuckle pads are a distinct finding on the dorsal surface; palmar nodules/cords are Dupuytren's.
• Using M72.2 (plantar fascial fibromatosis) for a palmar lesion — these are separate anatomic sites and separate codes; M72.2 is Ledderhose disease of the foot.
• Holding or downcoding to M79.89 (other soft tissue disorder) or R23.4 when the clinical note clearly confirms Dupuytren's — once the diagnosis is confirmed by physical exam or operative findings, M72.0 is correct.
• Assuming M72.0 requires a 7th character extension — it does not. M-codes in the fibroblastic disorders category carry no 7th-character requirement.
• Forgetting that M72.0 is an adult-only code (ages 15–124); a pediatric patient with palmar fibromatosis would require additional clinical scrutiny and may not map cleanly to M72.0.
