Endothelial keratoplasty (Descemet stripping endothelial keratoplasty, Descemet stripping automated endothelial keratoplasty, Descemet membrane endothelial keratoplasty, or Descemet membrane automated endothelial keratoplasty) may be considered medically necessary for the treatment of endothelial dysfunction, including but not limited to:
ruptures in Descemet membrane,
endothelial dystrophy,
aphakic and pseudophakic bullous keratopathy,
iridocorneal endothelial syndrome,
corneal edema attributed to endothelial failure,
and failure or rejection of a previous corneal transplant.
Femtosecond laser-assisted endothelial keratoplasty or femtosecond and excimer laser-assisted endothelial keratoplasty are considered investigational.
Endothelial keratoplasty is considered investigational when endothelial dysfunction is not the primary cause of decreased corneal clarity.
