ICD-10 Code H04.301 – Unspecified dacryocystitis of right lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.301 – Unspecified dacryocystitis of right lacrimal passage
What it is
This code identifies inflammation or infection of the right lacrimal sac, but the record does not specify the exact type. Use it when the provider documents dacryocystitis on the right side without further detail.
Clinical signs
Typical findings include tearing, tenderness, swelling, or redness near the inner corner of the right eye. Clinical features vary; refer to documentation.
When to use this code
Use H04.301 when the chart clearly states right-sided dacryocystitis and no organism, acuity, or other subtype is documented. It also fits cases where the diagnosis is confirmed clinically but remains unspecified in the note.
Do not use for
Do not use this code if the documentation identifies a different lacrimal disorder, such as canaliculitis or obstruction without inflammation. Also avoid it when the side is not right or when a more specific dacryocystitis code is recorded.
Coding tip
If the note only says “dacryocystitis” or is unclear on laterality, check documentation before assigning H04.301.
