ICD-10 Code L75.9 – Apocrine Sweat Disorder, Unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L75.9 – Apocrine sweat disorder, unspecified
What it is
L75.9 identifies a disorder of the apocrine sweat glands when the specific type is not documented. Use it when the record indicates an apocrine gland problem but does not name a more precise condition.
Clinical signs
Clinical features vary; refer to documentation. Findings may include localized apocrine gland dysfunction, abnormal sweating, or gland-related skin changes, but the chart must support the diagnosis.
When to use this code
Use L75.9 when the provider documents an apocrine sweat disorder without further detail. It also fits cases where the note confirms apocrine gland involvement but does not specify a named disorder. If the record describes a different sweat gland condition, choose the more specific code.
Do not use for
Do not use this code for general hyperhidrosis, bromhidrosis, or other clearly named sweat gland disorders unless the provider documents apocrine involvement. Check documentation if the diagnosis is uncertain.
Coding tip
Code to the most specific sweat gland diagnosis available; if the record is vague, query for clarification before defaulting to L75.9.
