Other bursitis of knee, left knee

This code signifies inflammation of a bursa in the left knee, excluding prepatellar, infrapatellar, and anserine bursitis. It indicates a non-specific bursitis affecting other bursae around the knee joint.

Apply this code when documentation specifies bursitis of the left knee that is not further specified as prepatellar, infrapatellar, or anserine. This code is appropriate when the physician's notes indicate "other bursitis of the left knee" or a specific bursa not covered by more granular codes (e.g., popliteal bursitis).

• Ensure the documentation clearly specifies "left knee" to avoid laterality errors.
• Differentiate from more specific knee bursitis codes (M70.4- for prepatellar, M70.5- for infrapatellar, M70.8- for anserine).
• Always review the physician's notes for the exact bursa involved; if specified, use a more precise code if available.
