ICD-10 Code H04.322 – Acute dacryocystitis of left lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.322 – Acute dacryocystitis of left lacrimal passage
What it is
H04.322 identifies an acute infection and inflammation of the left lacrimal sac and tear drainage passage. Use it when documentation specifies the left side and the condition is acute.
Clinical signs
Typical findings include pain, swelling, and redness near the inner corner of the left eye, sometimes with tearing or discharge. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents acute dacryocystitis affecting the left lacrimal passage or left lacrimal sac. It is appropriate for confirmed laterality in the record. If the note only says dacryocystitis without side or acuity, check documentation.
Do not use for
Do not use this code for chronic dacryocystitis or for infections not involving the left lacrimal drainage system. Check documentation if the side is unspecified or if the diagnosis is different.
Coding tip
Verify both acuity and laterality in the provider note before assigning H04.322.
