ICD-10 Code L74.8 – Other eccrine sweat disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L74.8 – Other eccrine sweat disorders
What it is
L74.8 identifies other disorders of the eccrine sweat glands that do not fit a more specific ICD-10 category. Use it when documentation names an eccrine sweating abnormality but gives no narrower diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abnormal sweating patterns involving eccrine glands, such as excess, reduced, or otherwise atypical sweating.
When to use this code
Use this code when the record clearly states an eccrine sweat gland disorder and no more specific code is documented. It is appropriate for provider-documented conditions that are not classified elsewhere in the L74 category.
If the note only describes sweating without a diagnosed disorder, check documentation before assigning L74.8. Code the documented condition as written, and do not assume a specific subtype.
Do not use for
Do not use L74.8 for generalized sweating complaints without a documented eccrine disorder. Also avoid it when a more specific diagnosis in the same category is recorded.
Coding tip
Confirm the provider explicitly links the finding to an eccrine sweat disorder before selecting L74.8.
