On November 4, 2020, CMS issued a proposed rule change for DME, HCPCS coding, and benefit category determinations - 85 FR 70358ff, here. The rule is not finaled, and groups may meet with the Office of Management and Budget (OMB) about the rule. See OMB page here, meeting page here (aka Executive Order/EO-12866 page). This shows a meeting with Abbott and OMB on 11/19, with Medtronic and OMB on 11/23. The decks are here and here, respectively.
The Abbott deck includes a slide that shows a marked disparity between white population states and black population states in the utilization of CGM per 100 individuals with diabetes. This rate ranged from 160/1000 for states with the highest white population, and down to 20/1000 for states with the highest black population, close to a ten-fold difference.
Separately, see a very powerful recent story in the LA Times about the impact of diabetes and amputations in minority communities - here. By journalist Joe Mozingo and photographer Francine Orr.
