ICD-10 Code H04.149 – Primary lacrimal gland atrophy, unspecified lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.149 – Primary lacrimal gland atrophy, unspecified lacrimal gland
What it is
This code identifies primary atrophy of a lacrimal gland when the affected gland is not specified. It refers to loss or shrinkage of the tear-producing gland without another stated cause.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see dry eye complaints, reduced tearing, or gland atrophy noted on exam or imaging.
When to use this code
Use this code when the record documents primary lacrimal gland atrophy and does not identify the right or left gland. It is appropriate when the provider states atrophy as the diagnosis and no secondary cause is documented. Check documentation if the note suggests inflammation, obstruction, or another specific lacrimal disorder.
Do not use for
Do not use this code for dry eye alone or for lacrimal gland disease with a documented cause, such as inflammation or injury. If the chart specifies a right or left gland, use the more specific code.
Coding tip
Confirm that “primary” and “unspecified lacrimal gland” are both supported in the note before assigning H04.149.
