Lacrimal fistula right lacrimal passage

This code signifies an abnormal, pathological connection or tract originating from the right lacrimal drainage system. This fistula allows for the discharge of tears or other fluid from the lacrimal passage to an external surface or another internal structure, bypassing the normal drainage pathway.

Apply this code when documentation explicitly states a lacrimal fistula is present in the right lacrimal passage. This includes congenital fistulas, or those resulting from trauma, infection, or surgical complications affecting the right eye's tear drainage system. Clinical notes should describe the location and laterality of the fistula.

• Ensure documentation specifies "right" lacrimal passage; otherwise, an unspecified laterality code may be more appropriate.
• Distinguish from dacryocystitis or other lacrimal gland disorders, which involve inflammation or other pathology without a fistulous tract.
• Code any underlying cause of the fistula (e.g., trauma, infection) as an additional diagnosis, if applicable and documented.
