42 CFR 436.531 - Determination of blindness.
In determining blindness -
(a) A physician skilled in the diseases of the eye or an optometrist, whichever the individual selects, must examine him, unless both of the applicant's eyes are missing;
(b) The examiner must submit a report of examination to the Medicaid agency; and
(c) A physician skilled in the diseases of the eye (for example, an ophthalmologist or an eye, ear, nose, and throat specialist) must review the report and determine on behalf of the agency -
(1) Whether the individual meets the definition of blindness; and
(2) Whether and when reexaminations are necessary for periodic redeterminations of eligibility, as required under § 435.916 of this subchapter. Blindness is considered to continue until the reviewing physician determines that the beneficiary's vision no longer meets the definition.
