ICD-10 Code H04.302 – Unspecified dacryocystitis of left lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.302 – Unspecified dacryocystitis of left lacrimal passage
What it is
This code identifies inflammation or infection of the left lacrimal sac or tear drainage passage when the documentation does not specify the type of dacryocystitis. It tells you the condition is on the left side and remains unspecified.
Clinical signs
Typical findings include tearing, tenderness, swelling near the inner corner of the left eye, and possible discharge. Clinical features vary; refer to documentation if the record does not clearly describe the presentation.
When to use this code
Use H04.302 when the provider documents dacryocystitis of the left lacrimal passage but does not name it as acute, chronic, or another specific form. It also fits when laterality is clear, but the exact subtype is not. If the note only says “lacrimal infection” or is ambiguous, check documentation before coding.
Do not use for
Do not use this code for dacryocystitis of the right side, bilateral disease, or a more specific documented type. Check documentation if the condition is elsewhere in the tear drainage system.
Coding tip
Code the laterality exactly as documented, and choose a more specific dacryocystitis code when the record names one.
