ICD-10 Code H04.021 – Chronic dacryoadenitis, right lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.021 – Chronic dacryoadenitis, right lacrimal gland
What it is
H04.021 identifies chronic inflammation of the right lacrimal gland, which helps produce tears. Use it when documentation specifies the right side and a long-standing, not acute, process.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings may include persistent swelling or tenderness near the outer upper eyelid, with possible tear production changes or a palpable lacrimal gland enlargement.
When to use this code
Use this code when the provider documents chronic dacryoadenitis affecting the right lacrimal gland. It also fits follow-up visits for established disease, if the diagnosis remains active and the right side is clearly identified.
Do not assume laterality from general “dacryoadenitis” wording. Check documentation if the record does not state chronicity or if another cause of lacrimal gland disease is described.
Do not use for
Do not use this code for acute dacryoadenitis, unspecified laterality, or left-sided disease. Check documentation if the note describes a different lacrimal disorder or a mass rather than inflammation.
Coding tip
Confirm both chronicity and right laterality in the provider note before assigning H04.021.
