THE ACCESS · WHAT HAPPENS TO A PATIENT?

The Border

The Crossroads’ crash start, zoomed in—how a person moves through the hospital, and the one place this atlas’s own law does not reach. Same building, same machine: the certification decides which country you are standing in.

The drawing in words

  1. Three jurisdictions are drawn as hairline regions—a region is whose law runs there. Region I, the hospital floor: 42 CFR 482, the hospital’s own law. Region II, the certified unit: 42 CFR 494, inside the hospital’s walls. Region III, the community: 42 CFR 494, where the chronic map runs. A dotted architectural outline marks the hospital’s walls—one building containing two countries. [1 · 2]
  2. The crash start—an ED presentation, then admitted, with acute kidney injury or new kidney failure. Region I.
  3. Acute inpatient haemodialysis—at the bedside or in an inpatient suite. Region I. The crash start leads here.
  4. No dialysis-specific condition exists here—the treatment rides the hospital’s general conditions: nursing 482.23, pharmacy 482.25, infection prevention 482.42, physical environment 482.41, QAPI 482.21. [1]
  5. Paid inside the MS-DRG—the stay, not the treatment. No ESRD PPS, no V-tags, no EQRS. [3]
  6. Surveyed as a hospital—an accreditor with deemed status, or the State agency. Never Appendix H. [4 · 5]
  7. Off the map—kidneys recover, no 2728 ever filed. [6 · 7]
  8. The AKI bridge, since 2017—a certified clinic may dialyze acute kidney injury, paid at the PPS base rate, no 2728 filed. Reached from acute inpatient haemodialysis by the uncommon route: discharged still needing dialysis, not yet chronic. If the person does not recover, the road runs on to the border crossing. [6 · 8]
  9. The border crossing—a stippled band between the hospital and the community. The CMS-2728 opens the federal record; the data system begins here. [6 · 7]
  10. The community clinic—the country the rest of this atlas maps. Region III.
  11. From the community clinic, any admission flips the rulebook at the door and runs back to acute inpatient haemodialysis; the person returns the same way at discharge. [2 · 3]
  12. Involuntary discharge, 494.180(f)—the discharge gate. Thirty-day notice to the patient and the Network; medical director and attending sign; another placement attempted and documented; the State agency is notified. If placement is found, the road returns to the community clinic. [2]
  13. The quiet census—a license held as a catch, three sessions a week until placement. Reached from the discharge gate by the uncommon route: no clinic will take them. Drawn as one lawful catch, never claimed as a norm: the placement-failure problem is documented; its prevalence is not. [2]
  14. The hospital-based chronic unit—its own CCN, the 2300 block. Corporate control, not the address, makes it hospital-based. Region II. [3 · 9]
  15. The full 494 machinery applies to that unit—V-tags, Appendix H survey, EQRS, QIP, the Network. [2 · 4]
