Calcific tendinitis, other site

This code signifies the presence of calcium deposits within a tendon, leading to inflammation and pain, specifically in anatomical locations other than the shoulder (M65.21-M65.24) or hip (M65.25). It represents a form of tendinopathy characterized by the pathological accumulation of hydroxyapatite crystals.

Use this code when documentation specifies calcific tendinitis affecting a site not otherwise specified by a more specific code, such as the elbow, wrist, knee, or ankle. Supporting documentation should clearly state the diagnosis of calcific tendinitis and the affected "other" anatomical location.

• Ensure the documentation explicitly rules out calcific tendinitis of the shoulder or hip before assigning this code.
• Always look for a more specific anatomical site code within the M65.2 series before defaulting to "other site."
• Verify laterality (right, left, bilateral) if specified in the clinical notes, as some M65.2 codes offer laterality options.
