Calcific tendinitis of unspecified shoulder

This code signifies the presence of calcium deposits within the tendons of the shoulder joint, leading to inflammation and pain. It specifically indicates that the laterality of the affected shoulder (left or right) is not documented or is unknown.

Apply this code when documentation confirms calcific tendinitis of the shoulder but does not specify which shoulder is affected. This is appropriate for initial encounters where laterality is still being investigated or when the provider explicitly states "unspecified shoulder."

• Avoid using this code if laterality (left or right) is clearly documented; instead, use M75.31 (right shoulder) or M75.32 (left shoulder).
• Ensure the medical record explicitly states "calcific tendinitis" and does not provide laterality for accurate code assignment.
• This code is often a placeholder; coders should query the provider for laterality if possible to achieve a more specific diagnosis.
