• Correct Add-on Codes


    Question: A patient who had surgery on the medial rectus muscle two years ago returned for inferior rectus muscle surgery. There is no scarring noted.  Which add-on code should be included?

    Answer: Since there was previous muscle surgery, use add-on CPT code 67332 Strabismus surgery on patient with scarring of extraocular muscles (eg, prior ocular injury, strabismus or retinal detachment surgery) or restrictive myopathy (eg, dysthyroid ophthalmopathy) in addition to primary surgical procedure.
