Does Medicare Cover Compression Garments for Lymphedema? The 2024 Benefit Sioux Falls Still Doesn't Know About
Medicare Part B has covered lymphedema compression garments only since January 1, 2024, under a new DMEPOS benefit category created by Section 4133 of the Consolidated Appropriations Act, 2023, per CMS's own MLN Matters MM13286 — before that date, Medicare paid for none of it, no matter how clearly a doctor documented the medical need. For 2026, coverage means 20% coinsurance after the $283 Part B deductible, and up to 3 daytime garments every 6 months plus 2 nighttime garments every 2 years, per affected limb. The single biggest reason a claim still gets denied, per Noridian Healthcare Solutions (South Dakota's Medicare DME contractor): the wrong or missing lymphedema diagnosis code, not a doctor's medical judgment overruled. A peer-reviewed review hosted by the National Library of Medicine puts breast cancer-related lymphedema incidence at a pooled 16.6% of patients, rising to 21.4% in studies that track people over time — a real slice of Minnehaha County's own 8.0% adult cancer prevalence, per CDC PLACES 2023. Here's the full guide: what changed and why, what's covered and what isn't, the exact diagnosis codes and modifiers that make or break a claim, a worked cost example under Original Medicare versus Medicare Advantage, and where to get fitted in Sioux Falls.

Chronic Condition Special Needs Plans: Why Sioux Falls Doesn't Have Medicare's Fastest-Growing Plan Type in 2026
National C-SNP enrollment jumped from about 674,500 people in 2024 to roughly 1.15 million in 2025, a 71% increase in a single year, per KFF's own analysis of CMS Medicare Advantage enrollment data — the first year this Special Needs Plan type outgrew every other kind combined. KFF's same analysis found 97% of C-SNPs nationally are built around diabetes or cardiovascular conditions, the exact two categories showing up most in Minnehaha County's own health data: 31.7% of adults have high blood pressure and 10.0% have diagnosed diabetes, per CDC PLACES 2023. Yet the CMS PY2026 Medicare Advantage/Part D Landscape file — the same federal dataset behind every plan count on this site — lists zero Chronic Condition Special Needs Plans anywhere in South Dakota, including Minnehaha County, for 2026. Here's the full guide: what a C-SNP actually is, the complete official list of all 15 CMS-approved qualifying conditions, why enrollment is exploding nationally, the real 11-plan Minnehaha County roster available instead, and what to actually do — including a real, separate Medicare benefit called Chronic Care Management — if you have a qualifying condition today.

Does Medicare Cover Mammograms? The Diagnostic Imaging Bill South Dakota Should Know About in 2026
Medicare covers one screening mammogram every 12 months at $0 for women 40 and older, per Medicare.gov, but a diagnostic mammogram — ordered for a symptom, a lump, or a callback on something the screening found — carries a 20% coinsurance after the 2026 Part B deductible of $283, per CMS National Coverage Determination 220.4. South Dakota patients carry the 2nd-highest average out-of-pocket share of the bill for breast cancer follow-up imaging of any U.S. state, 48.6% between 2018 and 2023, per the American Cancer Society Cancer Action Network's own claims analysis — even though the state's breast cancer mortality rate (17.3 per 100,000) runs below the U.S. average (19.2), per NCI's State Cancer Profiles. Starting with 2026 plan years, HRSA's updated Women's Preventive Services Guidelines require most private and ACA-marketplace health plans to cover follow-up breast imaging at $0 — a real federal fix, per the American College of Radiology and Mercer's own reporting — and Medicare is not included, since it still runs on a national coverage determination from 1978. Here's the full guide: why the reclassification happens mid-visit, the modifier CMS uses to flag it on your bill, a worked dollar example by month, dense-breast notification rules, and how Medigap Plan G or Medicare Advantage changes what you actually owe.
