ICD-10 Code L94.3 – Sclerodactyly (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L94.3 – Sclerodactyly
What it is
Sclerodactyly means hardening and tightening of the skin on the fingers, usually with reduced flexibility. It is a skin finding, not a complete diagnosis by itself.
Clinical signs
Typical findings include thickened, tight skin over the digits, limited finger motion, and a tapered or “claw-like” appearance. Clinical features vary; refer to documentation.
When to use this code
Use L94.3 when the record specifically documents sclerodactyly as the reason for coding. It may appear with connective tissue disorders, especially systemic sclerosis, but you should code only what is documented. If the note describes only generalized skin thickening, check documentation.
Do not use for
Do not use this code for Raynaud phenomenon, nonspecific hand stiffness, or skin changes without documented sclerodactyly. Check documentation if the provider names a broader systemic condition instead.
Coding tip
Assign L94.3 only when the provider clearly documents sclerodactyly, and code the underlying disease separately if it is recorded.
