ICD-10 Code H04.6 – Other changes of lacrimal passages (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.6 – Other changes of lacrimal passages
What it is
H04.6 identifies other noninfectious or nonspecific changes affecting the lacrimal passages, which drain tears from the eye. Use it when the record documents an abnormal lacrimal drainage condition that does not fit a more specific code.
Clinical signs
Clinical features vary; refer to documentation. Commonly, patients may have tearing, blockage symptoms, or abnormal drainage findings on eye examination, but the exact description should match the provider’s note.
When to use this code
Use H04.6 when the clinician documents an unspecified or other change in the lacrimal passages and no more precise diagnosis is given. It may apply to structural or functional abnormalities of tear drainage. If the note names a specific disorder, code that condition instead.
Do not use for
Do not use this code for acute infection, injury, or a clearly named lacrimal disorder with its own specific code. Check documentation if the record only describes tearing without a diagnosed lacrimal passage change.
Coding tip
Code H04.6 only after confirming the provider’s wording supports an “other change” in the lacrimal passages.
