Waters v. Becerra, No. 22-1997 (6th Cir. 2023)
Annotate this Case
Waters was born with homocystinuria and diagnosed with that condition at the age of six. Homocystinuria is a genetic attribute that causes metabolic issues that prevent Waters’s liver from metabolizing methionine, an amino acid, that produces L-cysteine, another amino acid. Her physician prescribed HCU coolers–a medical food containing a methionine-free protein formula. Waters ingests HCU coolers
orally; she has a fully functioning gastrointestinal tract. Waters sought reimbursement for HCU coolers purchased during 2018-2019, under the prosthetic-device benefit of Medicare Part B, 42 U.S.C. 1395k(a)(2)(I); 1395x(s)(8). The National Coverage Determinations Manual explains that, as part of the prosthetic-device benefit, enteral nutrition is considered reasonable and necessary when a patient “cannot maintain weight and strength commensurate with his” “general condition” because food does not reach the digestive tract and specifies that “[e]nteral therapy may be given by nasogastric [nose], jejunostomy [small intestine], or gastrostomy [stomach] tubes.” The NCD acknowledges “[s]ome patients require supplementation of their daily protein and caloric intake,” but “[n]utritional supplementation is not covered under Medicare Part B.”
The Sixth Circuit affirmed several levels of denial of Waters’s claim, acknowledging the difficult circumstances of Waters and her family. An HCU cooler is not a stand-alone prosthetic device based on the plain meaning of prosthetic “device” and because an HCU cooler is a medical food according to the FDA.
