Calcific tendinitis, right forearm

This code identifies a condition characterized by the deposition of calcium crystals within the tendons of the right forearm, leading to pain and inflammation. It represents a specific form of tendinitis where calcification is the underlying pathological feature affecting the extensor or flexor tendons of the forearm.

Apply this code when documentation explicitly states "calcific tendinitis" affecting the right forearm. Supporting clinical notes should describe symptoms such as localized pain, tenderness, and possibly limited range of motion in the right forearm, with imaging (e.g., X-ray) confirming calcium deposits within the tendons.

• Ensure laterality is clearly documented as "right forearm" to support this specific code.
• Distinguish from other forms of tendinitis (e.g., M77.01 for lateral epicondylitis, right elbow) if calcification is not specified.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter.
