Calcific tendinitis, unspecified lower leg

This code signifies inflammation of a tendon in the lower leg due to calcium deposits, where the specific tendon affected is not documented. It represents a non-traumatic, degenerative condition characterized by pain and restricted movement.

Apply this code when documentation clearly indicates calcific tendinitis of the lower leg, but the specific site (e.g., Achilles, peroneal) is not specified. This code is appropriate when imaging studies confirm calcification within a lower leg tendon, and the physician's diagnosis aligns with this finding without further anatomical precision.

• Avoid using this code if the specific tendon affected in the lower leg is known; instead, use a more precise code from the M65.26- subcategory.
• Ensure documentation supports the "calcific" nature of the tendinitis, typically through imaging reports.
• Consider laterality (left/right) if specified in the documentation; this code is for unspecified laterality.
