Pneumatic hammer syndrome, sequela

This code represents the long-term or residual effects of pneumatic hammer syndrome, also known as hand-arm vibration syndrome (HAVS). It encompasses the chronic neurological, vascular, and musculoskeletal damage to the upper extremities resulting from prolonged exposure to vibrating tools. Symptoms often include numbness, tingling, blanching of fingers, and reduced grip strength.

Apply this code for patients presenting with established, persistent symptoms or complications directly attributable to past pneumatic hammer syndrome. This is appropriate when the acute phase of injury has resolved, and the patient is experiencing ongoing sequelae. Use for follow-up visits, chronic management, or evaluation of long-term disability related to HAVS.

• Ensure documentation clearly links current symptoms to a history of pneumatic hammer syndrome.
• Always use in conjunction with codes for specific manifestations (e.g., peripheral neuropathy, Raynaud's phenomenon) to provide maximum specificity.
• Verify that the "S" seventh character for sequela is appropriate, indicating the residual effect of a past condition.
