ICD-10 Code H04.303 – Unspecified dacryocystitis of bilateral lacrimal passages (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.303 – Unspecified dacryocystitis of bilateral lacrimal passages
What it is
This code identifies inflammation or infection of the tear sacs on both sides when the record does not specify acute, chronic, or another type. Use it for bilateral dacryocystitis with unspecified detail.
Clinical signs
Typical findings include tearing, swelling, tenderness, or redness near both inner canthi. Clinical features vary; refer to documentation for whether the condition is acute, chronic, or associated with obstruction.
When to use this code
Use H04.303 when the provider documents dacryocystitis affecting both lacrimal passages and does not name a more specific form. It also fits when the note confirms bilateral disease but leaves the type unspecified. If laterality or acuity is clearer, code that documented detail instead.
Do not use for
Do not use this code for unilateral dacryocystitis or for cases documented as acute or chronic with a more specific code available. Check documentation if the problem is only tearing, obstruction, or another lacrimal disorder.
Coding tip
Always verify both laterality and specificity in the note before assigning an unspecified code.
