(unknown) Effective Date: N/A Surgery - Surgical Procedures on the Eye and Ocular Adnexa Feed
Conjunctivorhinostomy (fistulization of conjunctiva to nasal cavity); with insertion of tube or stent.
Modifiers may be applicable to indicate specific circumstances, such as bilateral procedures (modifier 50), increased procedural services (modifier 22), or distinct procedural service (modifier 59).
Medical necessity is established by documenting the patient's symptoms (e.g., excessive tearing, recurrent infections) and failed conservative treatments, confirming the need for surgical intervention to restore proper tear drainage.
The surgeon prepares the patient and administers anesthesia. An incision is made in the medial canthal area (inner corner of the eye), extending to the orbital rim. The bone below the medial canthus is exposed, and a hole is drilled into the nasal bone. Flaps from the conjunctival mucosa are sutured to the nasal mucosa to create a tract. A tube or stent is placed in the tract, and the area is checked for bleeding.
In simple words: The doctor creates a small opening between the eye and the nose to help tears drain properly. A small tube is placed in this opening to keep it from closing.
This procedure involves creating a new passageway between the conjunctiva (the membrane covering the eye) and the nasal cavity to address excessive tearing due to blocked tear ducts. A tube or stent is inserted to maintain the opening.
Example 1: A patient with excessive tearing due to a blocked tear duct caused by a fleshy growth., A patient with chronic dacryocystitis unresponsive to other treatments., A patient with canalicular stenosis or obstruction.
Documentation should include the cause of the tear duct blockage, previous treatments attempted, and the operative report detailing the procedure performed, including the type of tube or stent used.
