Other specified disorders of tendon, right hand

This code signifies a non-traumatic, non-inflammatory condition affecting a tendon in the right hand that is not specifically classified elsewhere. It encompasses various uncommon or ill-defined tendon pathologies, such as tendon thickening, calcification, or degeneration, when the specific type of disorder is not explicitly named by another ICD-10-CM code.

Use this code when documentation clearly indicates an "other specified" disorder of a tendon in the right hand, and more specific codes (e.g., for tenosynovitis, trigger finger, or rupture) do not apply. Supporting documentation should detail the nature of the tendon abnormality and its location in the right hand, ruling out more common or precisely defined conditions.

• Ensure the documentation specifies "right hand" to justify laterality.
• Always review for more specific codes first; this is a residual category.
• Distinguish from traumatic tendon injuries, which would typically fall under S66.- codes.
