Crepitant synovitis (acute) (chronic), right wrist

This code signifies inflammation of the synovial membrane of the right wrist, characterized by a crackling or grating sensation (crepitus) upon movement. This condition can be acute, indicating a sudden onset, or chronic, suggesting a long-standing or recurring issue. It often involves the tendon sheaths within the wrist joint.

Apply this code when documentation explicitly states crepitant synovitis affecting the right wrist. This diagnosis is typically supported by physical examination findings of crepitus, pain, and swelling in the right wrist, potentially confirmed by imaging studies like ultrasound or MRI showing synovial inflammation.

• Ensure documentation specifies "right wrist" to avoid laterality errors.
• Distinguish from other forms of synovitis without crepitus, which would map to different M70 subcategories.
• Look for associated conditions like overuse injuries or repetitive strain that may contribute to the synovitis.
