Answer: Unless your Medicare carrier has a local medical review policy that says you can bill 92225 (Ophthalmoscopy, extended, with retinal drawing [e.g., for retinal detachment, melanoma], with interpretation and report; initial) only one time, these codes refer to "initial" and "subsequent," rather than "new" and "established."
The CPT principle behind this language comes from hospital coding: When a recurrence of a condition requires hospitalization, the initial hospital visit code may be used again for the new admission.
Per CPT, 92225 is not intended to be a one-time-only code. Use 92225 for the initial extended ophthalmoscopy (EO) of new symptoms of a nonchronic condition, such as new flashes and floaters.
Scenario: You see a patient for a complaint of flashes and floaters, and perform an initial EO (92225). You find postvitreous detachment and ask the patient to return within six weeks.
At the subsequent visit, you perform an additional EO (92226). You find that the retina is intact, and you educate the patient about retinal detachment.
A few weeks later, the patient asks for a new appointment because she sees a spider web and new flashes, and you must perform another EO. Bill this as 92225 because it is a new event.
Scenario: A physician refers a diabetic patient to you for a consultation. The patent has diabetic retinopathy, a chronic condition. At the first appointment, you perform an initial EO (92225).
You ask the patient to return in a year for a dilated examination. In a year you perform a subsequent EO (92226). You do the same thing the following year, and again bill 92226, and so on.
Bilateral coding: Codes 92225 and 92226 are unilateral codes in the Medicare program.
If it is medically necessary to perform the procedure in both eyes - and you perform the drawing and report for both eyes - you can choose one of two coding options:
Rarely, a carrier will want units, so check with your carrier for any unit requirements. Make sure your documentation of medical necessity supports billing bilaterally.
