Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Coverage Summary

Not Medically Necessary / Unproven

All other FDA approved types of laser procedures are unproven and not medically necessary for treating any type of glaucoma due to insufficient evidence of efficacy and/or safety.

Unproven/Not Medically Necessary Laser Procedures: Any FDA-approved laser procedure for glaucoma not explicitly listed as proven above

Examples include excimer laser trabeculostomy/trabeculotomy (ELT), femtosecond laser trabeculotomy (FLT), OCT-guided laser trabeculotomy and other laser treatments not listed as proven; insufficient quality evidence of safety and efficacy

Document patient age (≤18 years) and the diagnosis of pediatric glaucoma when performing goniotomy or trabeculotomy in pediatric patients.

Patient age: ≤ 18 years
Diagnosis: pediatric glaucoma

Background & Evidence Summary

Glaucoma is a chronic, progressive optic neuropathy characterized by optic nerve and retinal nerve fiber layer abnormalities and visual field loss; severity is categorized as mild, moderate, severe, or indeterminate based on optic nerve/RNFL findings and standard automated perimetry (SAP).

Surgical options described include ab externo and ab interno canaloplasty (viscodilation of Schlemm’s canal), goniotomy, trabeculotomy (including circumferential/GATT), trabeculectomy, glaucoma drainage devices/shunts (e.g., EX-PRESS, Molteno, Baerveldt, Ahmed, Krupin, XEN), various MIGS approaches (trabecular bypass stents such as iStent/iStent inject, Hydrus; excisional goniotomy such as KDB; trabeculotomy/viscodilation devices such as OMNI, Streamline; ab interno canaloplasty/ABiC; suprachoroidal and subconjunctival shunts), and cyclophotocoagulation/ciliary body destruction. Laser procedures described include trabeculoplasty (ALT, SLT), iridotomy, and iridoplasty.

Microinvasive glaucoma surgery (MIGS) is defined as typically ab interno procedures usually combined with phacoemulsification, with a more favorable short-term safety profile but generally less IOP lowering than traditional filtering surgery. MIGS candidates are generally those with mild to moderate glaucoma and the procedures are expected to provide at least a 20% IOP reduction or a reduction of at least one glaucoma medication; many MIGS devices are indicated only when combined with cataract surgery.

Evidence topic	Summary
Pediatric surgical evidence	Multiple systematic reviews and RCTs support goniotomy/trabeculotomy for pediatric glaucoma; microcatheter-assisted circumferential trabeculotomy (IMCT) may be superior to conventional partial trabeculotomy but further long-term RCTs are needed
iStent combined with phaco evidence	Systematic reviews and RCTs show combined iStent (including iStent inject) plus cataract surgery reduces IOP and medication burden versus cataract alone with durable reductions up to 3–5 years in some studies
Hydrus evidence	RCTs (HORIZON) and systematic reviews indicate Hydrus plus cataract surgery increases medication-free rates and reduces need for additional glaucoma surgery versus cataract alone through 3–5 years; may be more effective than iStent short-term
Laser trabeculoplasty (LIGHT trial)	LIGHT trial: SLT provided better long-term disease control than drops; at 6 years ~69.8% in SLT arm remained at or below target IOP without medical/surgical intervention
Cyclodestructive procedures	Cochrane review: evidence inconclusive vs other glaucoma treatments; adverse events include hypotony and phthisis bulbi; larger RCTs needed
Canaloplasty (VENICE interim)	VENICE interim 6‑month RCT (Streamline vs iStent W, n=72): similar mean IOP reductions at 6 months; medication-free rates slightly higher for Streamline; study ongoing
OMNI	Case series and GEMINI/Gallardo studies: OMNI with phaco reduced mean diurnal IOP and medication use with ~78–80% medication-free at 6–12 months; evidence low quality, lacks randomized comparisons
KDB vs iStent	Systematic reviews, RCTs and comparative cohorts show phaco-KDB may have greater early surgical success versus phaco-iStent; by 12–24 months IOP reductions often become comparable; heterogeneity and bias limit conclusions
XEN Gel Stent evidence	Systematic reviews and observational studies indicate XEN lowers IOP (~25–44%) and medications with frequent needling and postoperative interventions; comparative studies suggest trabeculectomy may be somewhat more effective; evidence largely nonrandomized
