  • Age and weight for dosing calculations

Diagnostic Evidence:

  • Beta-glucosidase enzyme activity results (low levels)

  • Specialist consultation notes

Treatment Rationale:

Supporting Guidelines: Reference these authoritative sources:

From Our Advocates: We've seen cases where initial denials were overturned simply by providing more detailed genetic testing results. One patient's approval came after submitting comprehensive GBA sequencing that showed specific mutations, rather than just enzyme levels. Always include both enzyme and genetic confirmation when possible.

"Diagnosis not confirmed" Submit complete diagnostic workup Enzyme test + genetic testing + specialist notes
"Not medically necessary" Provide clinical evidence of disease burden Organ involvement studies, symptom documentation

"Dosing exceeds guidelines" Justify weight-based dosing Current weight, BSA calculation, specialist recommendation
"Experimental/investigational" Cite FDA approval FDA label showing approved indication for Type 1 GD
