Granuloma of unspecified lacrimal passage

This code signifies the presence of a granulomatous inflammatory lesion within an unspecified part of the lacrimal drainage system. This condition can lead to obstruction of tear flow, causing epiphora (excessive tearing) and potential secondary infections. The granuloma represents a localized collection of immune cells that form in response to chronic inflammation or infection.

Use this code when documentation specifies a granuloma affecting any part of the lacrimal passage (e.g., punctum, canaliculus, lacrimal sac, nasolacrimal duct) without further specificity regarding the exact anatomical location. This diagnosis is typically made based on clinical examination, imaging studies (e.g., dacryocystography), or biopsy results.

• Ensure the documentation explicitly states "granuloma" and specifies a lacrimal passage involvement.
• If the specific lacrimal passage is identified (e.g., lacrimal sac, nasolacrimal duct), use a more specific code from the H04.81 subcategory.
• Code any associated symptoms, such as epiphora (H04.2xx), or underlying causes if known and documented.
