ICD-10 Code L57.4 – Cutis laxa senilis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L57.4 – Cutis laxa senilis
What it is
L57.4 identifies cutis laxa senilis, an age-related loosening and wrinkling of the skin. It usually reflects chronic sun damage and skin aging rather than an acute disease process.
Clinical signs
Typical findings include thin, lax, wrinkled, and fragile skin, often with a sun-damaged appearance. Clinical features vary; refer to documentation if the record does not clearly describe the skin changes.
When to use this code
Use L57.4 when the provider documents senile cutis laxa, senile elastosis, or similar age-related skin laxity. It fits outpatient or specialist notes describing chronic skin looseness without another primary dermatologic diagnosis. Check documentation if the cause is unclear.
Do not use for
Do not use this code for generalized connective tissue disorders, inherited cutis laxa, or acute skin injury. If the chart describes a different dermatologic condition, code that diagnosis instead.
Coding tip
Confirm the provider links the skin laxity to senile or solar change before assigning L57.4.
