Crepitant synovitis (acute) (chronic), right hand

This code signifies inflammation of the synovial membrane, characterized by a crackling or grating sensation (crepitus), affecting the right hand. This condition can be acute or chronic and is often associated with overuse or repetitive strain.

Apply this code when documentation explicitly states "crepitant synovitis" or "tenosynovitis with crepitus" in the right hand. It is appropriate for both acute and chronic presentations of this inflammatory process. The physician's notes should clearly indicate the affected anatomical site and the presence of crepitus.

• Ensure the documentation specifies "crepitant" synovitis; simple synovitis without crepitus would be coded differently.
• Verify laterality; this code is specific to the right hand.
• Consider additional codes for underlying causes or associated conditions, such as repetitive strain injury (e.g., G57.81).
