How Charleston Nephrology Associates converts a verified Kidney Care Choices position into continuous, billable care for CKD progression, resistant hypertension, dialysis transitions, and transplant-list stability — the interstitial layer between quarterly office visits, where progression actually happens.
This is not a turnaround story. Charleston Nephrology Associates is an independent, physician-owned group of nine nephrologists and ten advanced-practice providers, already inside Medicare's flagship kidney model through its Kidney Contracting Entity — and the network's published results are exceptional. The strategic question is how to convert network-level performance into practice-level infrastructure, and get paid for the layer that produces it.
The CMS Kidney Care Choices CY2025 and CY2026 participant lists include the KCE (CKCC Professional option, GA/SC), and the KCE's published roster lists Charleston Nephrology Associates and all nine of its physicians.
Versus a 29% national average, as reported by the KCE — evidence that the network's kidney-care model outperforms when transitions are planned, not improvised.
Versus a 14% national average, as reported by the KCE — and it matches the practice's own clinical footprint across the metro's home-dialysis programs.
Two offices (North Charleston and Goose Creek), rounding at six hospital campuses, and coverage across the region's in-center and home dialysis clinics — the full arc of kidney care.
One structural gap remains: between quarterly office visits, the panel is clinically invisible. No practice-level RPM, PCM, or TCM program is marketed anywhere by the practice today — and progression, fluid overload, and unplanned dialysis starts happen precisely in that window.
Total-cost accountability for kidney care isn't on the horizon for this practice — it arrived with Kidney Care Choices. What changed for 2026 is that the operational answer is now cleanly reimbursable at the practice level.
Through Carolina Kidney Partners, the practice's physicians share accountability for total cost of care on aligned CKD 4–5 and ESRD beneficiaries. The KCE supplies predictive analytics and care coordinators at network level — what it cannot generate is a daily physiologic signal from each practice's own panel between visits. That layer belongs to the practice, and it is the instrument the contract's economics reward.
New codes 99445 (2–15-day device supply) and 99470 (first 10 minutes of management) remove the 16-day floor that previously blocked episodic monitoring — making post-discharge windows, post-access-placement recovery, and dialysis-transition stretches cleanly billable for the first time.
Principal Care Management (99426/99427) pays for monthly management of a single dominant condition — and CKD is the archetypal case. For a single-specialty renal panel, PCM carries the monthly care-management layer and stacks with RPM on the same patient, in the same month.
Not a device program bolted onto one diagnosis — a named, governed service line with its own P&L and scorecard, built for a renal panel: TCM at every discharge, RPM as the daily signal, PCM as the monthly management spine.
| Service | Codes | ~CY2026 Magnitude | Nephrology Use |
|---|---|---|---|
| Transitional Care Management | 99495 · 99496 | ~$200 / ~$280 | Every discharge from the six rounding campuses |
| RPM setup & device supply | 99453 · 99454 · 99445 (new) | ~$20 setup · ~$48/mo | 99445 unlocks 2–15-day transition windows |
| RPM treatment management | 99457 · 99458 · 99470 (new) | ~$49 + ~$40 add'l | Monthly review, titration, escalation |
| Principal Care Management | 99426 · 99427 | ~$65 + ~$52 add'l | Single dominant condition (CKD) ≥3 months |

Before any model upside, the service line must stand on its own P&L. Then the same infrastructure — enrollment, devices, alerts, escalation, documentation, billing — compounds through every layer of kidney-care value the practice already carries.
The practice runs on the Veradigm EMR family, with the FollowMyHealth patient portal already in patients' hands. CoachCare's integration catalog covers Veradigm: enrollment, discrete vitals, documentation, and claims-ready output land in the existing workflow — clinicians don't learn a new system. The exact product and version are confirmed in contracting.
Catalog integration pricing for the Veradigm family — one-time setup, monthly maintenance, per-patient fee. Final scope set by the exact product/version, confirmed at contracting.
The patient portal the panel already uses — remote-care enrollment builds on a digital front door that's already open, not a new app to sell from scratch.
A 24-month forecast for the practice: 19 referring providers across both offices, a dedicated on-site enrollment specialist staffed at CoachCare's expense, MAC-locality rates for zip 29405, Veradigm integration, and a 3% program discount. The modeled Medicare panel of ~1,850 is an estimate (plausible range 1,500–1,950) pending chart-count validation. KCE shared-savings upside and avoided-admission savings are not in these numbers — they are upside on top.

CoachCare operates as the service line's engine — enrollment outreach, device logistics, 24/7 monitoring, and billing-ready documentation — while Charleston Nephrology's physicians govern protocols and every clinical decision. Full-service delivery means launch requires no new practice headcount; the one-time implementation and EMR-integration fees land in month 1 (the forecast's only negative month), with cumulative breakeven in month 3.
Contracting (EMR product/version confirmation, BAA); Veradigm integration; standing orders and alert thresholds; enrollment specialist onboarded; chart-count validation of the panel estimate begins.
First cohort enrolled — CKD 3b–5 RPM plus renal PCM. Margin-positive from month two, cumulative breakeven in month three, first monthly scorecard delivered.
RPM census reaches its 333-patient ceiling in month 7; TCM handoff live at all six rounding campuses; first quarterly report aligned to the practice's KCE cycle.
PCM census 253 by month 12 (its 277.5 ceiling arrives in month 14); home-dialysis persistence and transplant-stability cohorts enrolled; panel validation complete and the Value Analysis re-run on chart counts.
The main office at 3815 Faber Place Drive in North Charleston is the natural first wave — it anchors the largest share of the panel, sits inside the six-campus hospital rounding loop where discharges surface, and puts the enrollment specialist where office visits, post-discharge follow-ups, and dialysis-education touchpoints already converge.
A main-office-first launch lets one site's physicians and staff shake out the workflow, then produces the internal evidence — census, capture rate, revenue per patient-month, unplanned-start signal — that makes the practice-wide rollout a data decision, not a leap.
| Milestone | Target |

| Veradigm integration + standing-order sign-off | Day 30 |
| First billable enrollments | Day 30–45 |
| Margin-positive monthly run rate | Month 2 |
