ICD-10 Code H04.143 – Primary lacrimal gland atrophy, bilateral lacrimal glands (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.143 – Primary lacrimal gland atrophy, bilateral lacrimal glands
What it is
This code identifies primary atrophy of both lacrimal glands, meaning the tear-producing glands have shrunk or lost function without another stated cause. It points to bilateral gland involvement and reduced tear production risk.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include dry eye symptoms, reduced tear secretion, ocular irritation, or bilateral lacrimal gland shrinkage on exam or imaging.
When to use this code
Use H04.143 when the provider documents primary atrophy affecting both lacrimal glands. Code it when the record clearly distinguishes this from secondary gland damage, obstruction, or another tear disorder. If the note only says dry eyes, check documentation before assigning this code.
Do not use for
Do not use this code for nonspecific dry eye, lacrimal gland inflammation, or lacrimal obstruction. If the cause is secondary or unspecified, check documentation and choose the more accurate diagnosis.
Coding tip
Confirm that “primary” and “bilateral” are both documented before assigning H04.143.
