Clinical & Coding Specifications
Clinical Context
A patient with age-related macular degeneration or other retinal vascular disease presents to an ophthalmology clinic for intravitreal therapy. The medication billed under Q4310 (Procenta, per 100 mg) is prepared by the clinic pharmacy or a specialty pharmacy and delivered for intravitreal injection. Typical workflow: the ophthalmologist documents diagnosis and treatment plan, pharmacy compounds or dispenses the appropriate vial or syringe of Procenta dosed per 100 mg units, nursing verifies patient identity and allergy status, obtains informed consent, applies topical antisepsis and anesthetic, and the physician performs an intravitreal injection in the clinic procedure room or ambulatory surgical center. Post‑injection, the patient is observed for acute complications (e.g., increased intraocular pressure, endophthalmitis) and given follow‑up instructions. Billing for Q4310 is submitted by the dispensing provider or facility to payors along with the associated injection procedure code and relevant diagnosis codes for retinal disease.
