ICD-10 Code L75.2 – Apocrine miliaria (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L75.2 – Apocrine miliaria
What it is
L75.2 identifies apocrine miliaria, a disorder involving blockage or irritation of apocrine sweat glands. It is used when the record specifically names this condition.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe a sweat-gland disorder affecting apocrine areas, often with localized skin changes consistent with gland obstruction.
When to use this code
Use L75.2 when the clinician documents apocrine miliaria by name. Code it for encounters focused on this diagnosis, even if the note describes a localized rash or sweat-gland problem rather than repeating the term.
Check documentation when the chart only says “miliaria” or “heat rash,” because those terms may not mean apocrine miliaria. If the diagnosis is uncertain, avoid assuming this code.
Do not use for
Do not use L75.2 for nonspecific miliaria, heat rash, or other sweat disorders unless apocrine miliaria is clearly documented. Check documentation if the condition is described in broader or different terms.
Coding tip
Assign L75.2 only when the provider explicitly links the condition to apocrine miliaria; otherwise, verify the exact diagnosis in the note.
