ICD-10 Code H04.15 – Secondary lacrimal gland atrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.15 – Secondary lacrimal gland atrophy
What it is
H04.15 identifies secondary atrophy of the lacrimal gland, meaning the tear-producing gland has become wasted or reduced in size due to another cause. Use it when documentation clearly states secondary lacrimal gland atrophy.
Clinical signs
Clinical features vary; refer to documentation. Patients may have reduced tear production, dry eye complaints, or a history suggesting an underlying disorder affecting the gland.
When to use this code
Use H04.15 when the provider documents secondary lacrimal gland atrophy as the diagnosis. It may apply after prior inflammation, autoimmune disease, radiation, or other documented causes, but you should code only what is stated in the record.
If the note describes dry eye without gland atrophy, do not assume this code. Check documentation for explicit mention of secondary atrophy or a clear equivalent term.
Do not use for
Do not use this code for nonspecific dry eye, lacrimal gland inflammation, or congenital lacrimal gland abnormalities. If the record does not confirm atrophy, check documentation.
Coding tip
Code the underlying condition separately when documented, and use H04.15 only when secondary lacrimal gland atrophy is explicitly identified.
