Calcific tendinitis, left forearm

This diagnosis code signifies the presence of calcific tendinitis affecting the tendons of the left forearm. It indicates a condition characterized by the deposition of calcium crystals within the tendon tissue, leading to pain, inflammation, and impaired function in the specified anatomical region.

Apply this code when documentation explicitly states calcific tendinitis located in the left forearm. This typically occurs in patients presenting with localized pain, tenderness, and restricted range of motion in the left forearm, often confirmed by imaging studies showing calcium deposits.

• Ensure laterality is clearly documented as "left forearm"; avoid using for unspecified or right forearm involvement.
• Distinguish from other forms of tendinitis (e.g., M77.02 for lateral epicondylitis, left elbow) where calcification is not specified.
• Look for supporting documentation from X-rays, MRI, or ultrasound confirming calcium deposits within the forearm tendons.
