Carriers are finicky about 92135 - check this list for approved diagnoses Scanning laser glaucoma testing (SLGT) is a young technology, and while most carriers will reimburse for it, you must still be sure to document medical necessity for 92135 (Scanning computerized ophthalmic diagnostic imaging with interpretation and report, unilateral). Not so fast: "You really need to consult your Medicare carrier for Medicare patients," says David Gibson, OD, FAAO, an optometrist practicing in Lubbock, Texas.

Aetna, for example, still considers the scanning laser "experimental and investigational," and will not approve 92135 for any diagnosis.
Example: Below are the ICD-9 codes that one carrier, Empire Medicare Services of New York and New Jersey, will accept with 92135.
