Calcific tendinitis, unspecified forearm

This code signifies an inflammatory condition of a tendon in the forearm characterized by the deposition of calcium crystals. This calcification can lead to pain, stiffness, and reduced range of motion in the affected area. The "unspecified" nature indicates that the specific tendon involved in the forearm is not documented.

Apply this code when documentation clearly states calcific tendinitis of the forearm, but the laterality (left or right) and the specific tendon (e.g., extensor carpi radialis, flexor carpi ulnaris) are not specified. This is appropriate when imaging reports (X-ray, ultrasound) confirm calcium deposits within a forearm tendon.

• Avoid using this code if laterality (left or right forearm) is documented; instead, choose a more specific code (M65.231 or M65.232).
• Ensure the documentation explicitly mentions "calcific" tendinitis, not just general tendinitis.
• Query the provider for laterality and specific tendon if possible to allow for more precise coding.
