ICD-10 Code H04.413 – Chronic dacryocystitis of bilateral lacrimal passages (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.413 – Chronic dacryocystitis of bilateral lacrimal passages
What it is
H04.413 identifies long-standing inflammation or infection of both lacrimal sacs. Use it when documentation states chronic dacryocystitis affecting the bilateral lacrimal passages.
Clinical signs
Typical findings include recurrent tearing, medial canthal tenderness, and discharge from the puncta. Clinical features vary; refer to documentation if the note does not clearly confirm chronic bilateral involvement.
When to use this code
Use this code when the provider documents chronic dacryocystitis in both lacrimal passages or both lacrimal sacs. It is appropriate for ophthalmology notes describing persistent or recurrent inflammation rather than an acute episode. Check documentation if laterality is unclear.
Do not use for
Do not use it for acute dacryocystitis, unspecified laterality, or isolated unilateral disease. If the record does not specify chronic bilateral involvement, check documentation.
Coding tip
Confirm both chronicity and bilateral laterality in the assessment before assigning H04.413.
