ICD-10 Code H04.813 – Granuloma of bilateral lacrimal passages (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.813 – Granuloma of bilateral lacrimal passages
What it is
This code identifies a granulomatous lesion affecting both lacrimal passages, which are part of the tear drainage system. It indicates a localized inflammatory mass or nodule documented as bilateral.
Clinical signs
Findings may include swelling, redness, tenderness, or obstruction-related tearing around both tear drainage pathways. Clinical features vary; refer to documentation.
When to use this code
Use H04.813 when the provider documents a granuloma in both lacrimal passages, including bilateral canalicular or nasolacrimal involvement. You should also use it when the diagnosis is clearly stated in an ophthalmology or ENT note and supported by the record.
Do not use for
Do not use this code for unspecified lacrimal inflammation, simple obstruction, or a unilateral granuloma. Check documentation if the site, laterality, or lesion type is unclear.
Coding tip
Confirm both laterality and the exact lacrimal structure before assigning H04.813.
