ICD-10 Code H04.001 – Unspecified dacryoadenitis, right lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.001 – Unspecified dacryoadenitis, right lacrimal gland
What it is
This code identifies inflammation of the right lacrimal gland when the chart does not specify the cause. It is used for a nonspecific dacryoadenitis affecting the right side.
Clinical signs
Typical findings include swelling or tenderness in the outer upper eyelid area, sometimes with redness or a palpable mass. Clinical features vary; refer to documentation.
When to use this code
Use H04.001 when the provider documents dacryoadenitis of the right lacrimal gland but does not identify a more specific etiology. It also fits when laterality is clear and the record supports the right side only. If the note names an infectious, autoimmune, or other specific form, code that diagnosis instead.
Do not use for
Do not use this code for left or bilateral lacrimal gland inflammation, or for a more specific type of dacryoadenitis. Check documentation if the condition is actually another eyelid, tear duct, or orbital disorder.
Coding tip
Verify both laterality and whether the provider documented a specific cause before assigning this unspecified code.
