What Blue Cross Blue Shield of Michigan's policy requires for glaucoma (drops + procedures + surgery)

Cited policy: BCBS Surgical Treatment of Glaucoma — Trabeculectomy and Tube Shunts

Medically uncontrolled glaucoma despite max tolerated medical therapy + SLT (or contraindication). Progressive VF / OCT loss. Trabeculectomy with MMC OR tube shunt (Baerveldt 350/250, Ahmed FP7, ClearPath) per surgeon judgment. Combined phaco-trab when concurrent visually significant cataract.

How Blue Cross Blue Shield of Michigan denies glaucoma (drops + procedures + surgery) — and how to counter it

Where Blue Cross Blue Shield of Michigan pushes back: 1) Tube shunt experimental as primary surgery; 2) Trabeculectomy required first; 3) MIGS first.

Counter-arguments that hold up: Tube shunts FDA-cleared decades — NOT experimental. PTVT 5-yr (Gedde Ophthalmology 2022;129:1344-1356) — tube and trabeculectomy SIMILAR IOP and failure rates as PRIMARY surgery in eyes without prior incisional. TVT 5-yr (Gedde Am J Ophthalmol 2012;153:789-803) — tube HIGHER success in re-operations. Tubes have lower late hypotony, bleb leak, blebitis, endophthalmitis risk vs trab. AAO POAG PPP 2020 endorses tube as primary option in select indications (uveitic glaucoma, neovascular, prior conjunctival scarring, contact-lens wearers). MIGS not appropriate for advanced disease per AGS.
