Infective myositis, unspecified finger(s)

This code signifies an inflammatory condition of the muscle tissue in an unspecified finger, caused by an infectious agent. This typically presents with pain, swelling, and tenderness in the affected finger, often accompanied by signs of infection such as warmth or redness. The infection can be bacterial, viral, fungal, or parasitic.

Use this code when documentation clearly indicates infective myositis affecting a finger, but the specific finger (e.g., thumb, index, middle, ring, little) is not specified. This code is appropriate when the physician's notes describe an infection of the muscle tissue of a digit without further anatomical detail.

• Ensure the documentation explicitly states "infective myositis" or a similar diagnosis indicating muscle inflammation due to infection.
• If the specific finger is documented (e.g., "infective myositis of the left index finger"), use the more specific M60.042 or M60.045 code.
• Always code the underlying infectious agent (e.g., B95-B97 for bacterial infections) as an additional diagnosis, if known and documented.
