Gas Permeable Scleral Contact Lens
Blue Cross Blue Shield Association policy 9.03.25 (BCBSMS policy L.9.03.403) states that rigid gas permeable scleral lenses may be considered medically necessary for patients who have not responded to topical medications or standard spectacle or contact lens fitting. The listed conditions are corneal ectatic disorders, corneal scarring and/or vascularization, irregular corneal astigmatism, and ocular surface disease with pain and/or decreased visual acuity. Use of a rigid gas permeable scleral lens for any other condition is considered not medically necessary, and the most recent policy update dated 03/11/2026 removed ICD-9 diagnosis codes from the policy.
