ICD-10 Code H04.612 – Lacrimal fistula left lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.612 – Lacrimal fistula left lacrimal passage
What it is
H04.612 identifies an abnormal opening, or fistula, involving the left lacrimal drainage passage. Use it when documentation specifies a left-sided tear duct fistula.
Clinical signs
Clinical features vary; refer to documentation. Commonly, a lacrimal fistula may be noted as a small external opening near the inner eye area with tearing or drainage from the left side.
When to use this code
Use this code when the record clearly states a fistula of the left lacrimal passage, including postoperative or acquired cases if documented as such. It is appropriate when the clinician identifies the left side and the abnormal tract is the primary diagnosis being coded.
Do not use for
Do not use this code for nonspecific tearing, blocked tear ducts, or right-sided or bilateral lacrimal disorders. If the note does not confirm a fistula, check documentation.
Coding tip
Confirm laterality and the word “fistula” in the provider note before assigning H04.612.
