A Scalable, Profitable Remote Care Service Line for Columbia Nephrology Associates

19 nephrologists, four offices, rounding at fifteen dialysis units, and a Medicare panel whose kidney disease and hypertension prevalence sits at the ceiling CMS publishes to. The practice already bills care management and already carries total-cost accountability through Kidney Care Choices. What it does not have is a daily signal from the panel between visits. This is that layer: transitional care at discharge, remote blood-pressure and weight monitoring, and principal care management for the months after, staffed and run by CoachCare inside athenahealth, with the practice keeping 42.2% of net reimbursement over 24 months.

Unique Patients in Active Remote Care at Month 24

Year 1 margin 41.6%, Year 2 42.4%. Enrollment begins in month 1; month 1 runs −$1,369 while setup posts against a small census, and the practice is positive from month 2 onward. The headline is 2,504 unique patients; the enrollment chart shows 3,117 active program enrollments, because a patient on both programs is one patient and two enrollments.

Where the Practice Is Today

The Panel Is Already a Kidney Program. The Months Between Visits Are Not.

This is not a pitch for something new. The practice's own CY2024 Medicare claims show one of the highest-acuity outpatient panels in the state, a care-management program that already exists, and a precise picture of where the billing stops.

✓ The panel is the argument

Risk score 3.54, average age 73

Across 32 billing clinicians and $5.42M of Medicare allowed in CY2024: chronic kidney disease, hypertension and hyperlipidemia all report at 75%, the ceiling CMS publishes to · diabetes 62% · heart failure 48% · ischemic heart disease 51% · atrial fibrillation 33%. About 4,800 established patients were seen for a follow-up visit in the year, and roughly 3,800 beneficiaries were followed in the hospital.

✓ Care management is already billed

946 patients on chronic care management

Nineteen clinicians billed 99490 in CY2024 for 946 beneficiaries. That is the hard part, consent and a monthly documented touch, already in the practice's habits. The program bills about a quarter of the months it could: 2,802 claims on 946 patients is roughly three billed months per patient per year, and about one established patient in five is in it.

The gap

No remote monitoring. No transitional care.

99453, 99454, 99457, 99458 and 99495/99496 are absent from the CY2024 claims for every clinician: no program at meaningful scale. On a panel where three patients in four carry hypertension and one in two carries heart failure, no blood pressure or weight is being read between visits, and the 3,800 hospital follow-ups produced no transitional-care claim.

The extension, in one sentence: the consent-and-monthly-touch workflow that already reaches 946 patients three months a year becomes a twelve-month program with a cuff and a scale in it, and it reaches the rest of the 4,800 established patients with the same diagnoses. The practice does not need to learn care management. It needs the layer that makes it pay every month and feeds the model it is already accountable under.
The Second Ledger

The Practice Is Already Accountable for Total Kidney-Care Cost

Columbia Nephrology Associates is a participant in the CMS Kidney Care Choices model through Carolina Kidney Partners, a physician-led Kidney Contracting Entity in the Professional option since the model's first performance year. Under that arrangement the practice's physicians share in savings and losses on the total cost of care for aligned late-stage CKD and dialysis patients, are scored on quality, and are paid on optimal dialysis starts. The entity supplies analytics and care coordination at the network level. What it cannot produce 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.

The model's current performance period ends December 31, 2026. Whatever follows it, and CMS has said the destination is risk-based, per-member payment reconciled against outcomes, will score the same things: fewer unplanned admissions, more planned starts, more home dialysis, and documented monthly management of the patients most likely to crash into the hospital. A service line that produces those results as fee-for-service margin today is the practice's position for that negotiation.

Verified

The Instrument

Daily blood pressure and weight

Fluid overload and uncontrolled pressure are what turn a stable CKD 4 patient into an admission and a crash start. Both are visible days ahead on a cuff and a scale, and invisible between quarterly visits.

What the Layer Produces

Avoided Admissions Write to Both Ledgers

A CKD admission that does not happen is fee-for-service margin for the service line and, for an aligned patient, a dollar that stays under the entity's benchmark. The same program writes to both.

204

Hospitalizations avoided over 24 months

At the model's generic 20% annual admission rate. A CKD 3b–5 cohort with 48% heart-failure prevalence admits well above that; at 40% the figure is about 408.

$3.06M

Acute-care spend that never occurs

At $15,000 per admission, before any shared-savings split. None of it is in the Value Analysis below, which prices the fee-for-service codes only.

The Service Line

One Pathway, From Discharge to Steady State

Three billing families, one clinical workflow, one care team. A patient enters wherever they are, coming out of the hospital, newly overloaded, freshly cannulated, or overdue for real between-visit management, and stays on the same pathway through progression, access placement and the transition to dialysis or transplant.

The Nephrology Stack: TCM → RPM → PCM
  • TCMTransitional Care Management (99495 / 99496) at every discharge from the six hospitals where the practice rounds: contact within two business days, the visit within 7 or 14 days, medications and fluid plan reconciled. The practice already does this work and bills the office visit for it. At this locality the codes pay $209.97 and $284.94. Not in the forecast below; it is the fastest first dollar.
  • RPMCellular blood pressure cuff and scale, readings reviewed daily by a named care manager. The CY2026 codes 99445 and 99470 make the first two weeks after a discharge, an access placement or a dialysis start billable on their own; in this forecast they carry about $479,000, revenue that did not exist under the CY2025 schedule.
  • PCMPrincipal Care Management (99426 / 99427) is the monthly care-management code for a patient whose care centers on one serious condition, and CKD is the textbook case. Paired with RPM on the same patient, in the same month. PCM and CCM cannot both be billed for one patient in one month; the existing CCM panel migrates or stays, patient by patient, at the practice's direction.
Who Does the Work
  • EngineEnrollment outreach, cellular devices, 24/7 alert triage, nurse follow-up, documentation and billing-ready claims, operated by CoachCare and governed by the practice's nephrologists under one protocol.
  • StaffingCoachCare places a funded on-site enrollment specialist in the practice and supplies the care-management team behind the monthly time. The clinicians order, oversee and bill; the recurring labor sits on CoachCare's payroll. Embedded in the fee, never deducted from the practice's margin. At month 24 the census needs about 15 care managers at 165 patients each, none on the practice's payroll.
  • Payer mixAbout 44% of Medicare beneficiaries across the practice's four counties are in Medicare Advantage, so most of the panel is still traditional Medicare. Plans must reimburse at least the Medicare rate for these code families; that is a floor, and individual contracts set their own terms. The forecast is priced at the Medicare rate throughout.

Integration

Built Into the athenahealth Workflow

CoachCare is an athenahealth integration partner. Enrollment flags and orders leave the chart; vitals, care documentation, enrollment status and billing-ready claims come back into it. Clinicians stay in athenaOne, and the practice's billing team does not learn a new claim path.

athenahealth The practice's chart, all four offices One chart per patient Enrollment flags by service Orders and referrals Patient portal Practice billing CoachCare Remote care platform + care team Cellular BP cuffs & scales 24/7 monitoring Care managers, ~165:1 On-site enrollment specialist Billing engine FROM THE PRACTICE Enrollment flags and orders by service Patient health history BACK TO THE PRACTICE Integrated vital reports and alert dispositions Evidence of care, vitals and care plan, monthly Real-time enrollment status Claims created automatically, every patient, every month Clinicians stay in the chart they already use; the program lives alongside it

Integrated enrollment

Enrollment flags and ordering by service inside the athenaOne workflow; the on-site specialist works the list, and patients begin receiving services within days.

Documents in the chart

Evidence of care, vitals and care plans attach to the patient's chart monthly, which is what makes the time-based claim defensible under audit.

Automated claims

The CoachCare billing engine creates the claim for every enrolled patient every month, removing the manual claim step the practice's billing team would otherwise carry.

Integration setup for athenahealth runs $1,000 one time, with a $150 monthly interface fee and $1.50 per enrolled patient per month. Those figures are carried in the financial summary below and confirmed in contracting.

Clinical Governance & Escalation

Every Reading Runs Through One Escalation Engine

The Value Analysis shows the program pays. This is the part that says it is safe, and that 19 nephrologists see signal rather than a thousand readings a day.

Reading arrivesCellular device transmits; the value is checked against the patient's individual thresholds, set by the nephrologist at enrollment.
→
Critical value?Escalates immediately, regardless of symptoms. Everything else goes to a retake and a symptom check first.
→
Trend defined objectivelyThree blood-pressure readings at least an hour apart, or a weight gain of three pounds in a day or five in a week, the fluid signature that precedes an admission.
→
Unreachable patientVoicemail plus scheduled callback; a critical value or a confirmed trend escalates anyway.
→
DocumentedVital, findings, method, contact, outcome and follow-up, written to the athenahealth chart every time.
Emergent

911 with the patient on the line

Chest pain, new shortness of breath, stroke signs, syncope, sudden swelling, a bleeding or non-thrilling access. CoachCare's urgent and emergent policy supersedes any practice-specific preference. If the patient refuses, the clinic is notified; otherwise CoachCare activates 911.

Non-critical

To a named member of the practice

Out-of-range but not emergent findings route to the clinician or nurse the practice designates in the charter, with the readings, the symptom check and the recommended next step attached.

Stable, resolved

FYI in the record

A retake that lands in range and a clean symptom check closes the loop with a chart note and nothing else. The nephrologist's inbox is reserved for what needs a decision.

Continuity

Re-escalation on a fixed cadence

An unreachable patient is re-attempted on a schedule, the practice is notified at every decision point, and a patient who stops transmitting is worked before a billing month is lost.

The Post-Discharge Cadence

Any emergency visit or hospitalization in the preceding 60 days triggers three touches inside two weeks, and when the patient was admitted it is also the TCM episode. The same cadence follows an access placement and the first weeks of a dialysis start. On this panel, that cadence is where the modeled 204 avoided hospitalizations over 24 months come from.

Day 1–2

Reach the patient, reconcile medications and the fluid and potassium plan against the discharge instructions, confirm the cuff and scale are transmitting.

Day 5–8

Weight and pressure trend reviewed, diuretic or antihypertensive plan confirmed with the nephrologist, follow-up appointment confirmed with the practice.

Day 12–14

Close the episode or extend it; anything trending is escalated through the engine above.

CoachCare Value Analysis · Modeled for Columbia Nephrology Associates

The Value Analysis

A 24-month forecast for the RPM + PCM stack: 8,540 Medicare patients in scope, the practice's estimated panel, sized from its own CY2024 established-visit beneficiaries and the Medicare Advantage share of its four counties. 30 referring clinicians, one CoachCare-funded on-site enrollment specialist, South Carolina locality rates and the athenahealth integration. Shared savings and transitional care are not in these numbers.

Active Program Enrollments by Program

Monthly active enrollments (services, not patients), net of attrition. Remote monitoring reaches its ceiling of 2,242 in month 21; principal care management is at 876 of a 2,178 ceiling at month 24 and still climbing.

Monthly Economics: Reimbursement, Fees, Net to the Practice

Net reimbursement after denials and coinsurance bad debt versus CoachCare fees. Month 1 absorbs the one-time setup; net to the practice is positive from month 2 onward.

24-Month Net Reimbursement Mix

$3.77M across the RPM + PCM stack. Remote monitoring carries the larger share, which is what a hypertension-and-volume panel on daily devices should produce.

Read the Curves Correctly

Monitoring Fills Its Pool. Care Management Is Still Climbing.

Two constraints, one per program. Remote monitoring reaches its eligibility ceiling in month 21; from there its census holds and the only way up is a wider cohort or a higher acceptance rate from the chart. Principal care management is the opposite case: at month 24 it holds 876 of a 2,178 ceiling, so its constraint is enrollment pace, and every unit of enrollment capacity keeps moving it.

ProgramEnrollment ceilingHow it is definedMonth 24
RPM2,2428,540 in scope × 75% eligible × 35% acceptance2,242
PCM2,1788,540 in scope × 85% eligible × 30% acceptance876
At month 24—Active program enrollments = 2,504 unique patients3,117

Eligibility is set for a nephrology Medicare cohort. Every point of eligibility or acceptance the practice's own chart data supports beyond these raises the monitoring ceiling, and the forecast, directly. Year 1 lands at 1,405 unique patients.

Enrollment staffing24-mo net reimbursementNet to practiceUnique, M24
Practice referrals only, no on-site specialist$2,795,697$1,174,3652,078
One CoachCare-funded on-site specialist (this forecast)$3,768,364$1,591,1752,504
Two specialists$4,498,667$1,908,2112,596
Three specialists$5,089,765$2,168,1162,688

A second specialist reaches the monitoring ceiling months sooner and keeps lifting the care-management census, which is why the month-24 unique count moves here where it would not on a panel that fills in a year. Without a funded specialist the practice's own referral flow reaches well under half the forecast.

The objection this answers: "our people already do care management." They do, for about 946 patients, about three months a year each. The gap between that and 2,504 patients twelve months a year is 15 full-time care managers and an enrollment function, and the row without a specialist shows what the practice's own outreach produces on its own.
Implementation

Chartered in 30 Days.
Enrolling by Day 45.

CoachCare operates as the service line's engine while the practice's nephrologists govern protocols and every clinical decision. Full-service delivery means launch needs no new hires, the athenahealth integration is native, and the transitional-care path produces cash before any device ships.

The first 90 days, modeled: 54 active program enrollments by month 1, 143 by month 2, 266 by month 3, led by the CKD 3b–5 and resistant-hypertension cohorts, the existing care-management panel, and the post-discharge list from the six hospitals where the practice rounds.
The ask: a working session with the practice's physician leadership and administrator to validate the cohort against the chart, decide how the existing care-management panel migrates, confirm the clinician roster the forecast is built on, and set the go-live at the Columbia office.
Days 1–14

Charter and Cohort

Agree the escalation routing and who receives non-critical alerts. Pull the CKD 3b–5, resistant-hypertension and heart-failure cohorts out of athenahealth, reconcile them against the existing care-management panel, and confirm the enrollable list against the panel estimate in this analysis.

Days 15–30

Integration and Billing

Turn on the athenahealth integration, configure the time-capture and code mapping, and run a claims test on the transitional care management path first.

Days 31–45

Enrollment Specialist On Site

The funded specialist starts at the Columbia office, working from the confirmed cohort list, then extends to West Columbia, Lugoff and Sumter. Devices ship to enrolled patients. First readings arrive and the escalation engine goes live with the practice watching every route.

Month 3 onward

Steady State

The census builds toward the ceilings in the analysis. Blood-pressure control, fluid management, post-discharge touches and planned-start documentation accumulate as retrievable reports, which is what the Kidney Care Choices quality measures and any successor model both need.

Policy Watch · CMS-1848-P

2027 Proposed Rule Insights

CMS has proposed cutting the remote-monitoring device-supply codes for CY2027. The proposal is narrower than the headline. Here is what it does to the forecast on this page, priced at the South Carolina locality amounts the forecast itself uses rather than national averages.

01

What is actually in scope

The proposal reaches the remote-monitoring family only. Principal care management is not in it, and on this forecast PCM carries $942,760 of the $3,768,364 in 24-month net reimbursement. Its own amounts move by well under a point through the conversion factor, so $5,201 of the $270,049 total sits outside the remote-monitoring arm.

02

How CoachCare is preparing

Two contingencies are already in build. An unbundled arrangement, with the software platform, device logistics and program enablement priced separately, and an arrangement in which CoachCare manages the staffing while the practice owns the clinical program and the billing. Whichever way the final rule lands, the program does not have to be rebuilt.

03

Where this is heading

CMS's ACCESS Model points at the destination: remote care paid as a risk-based per-member-per-month amount, with half of each payment withheld and reconciled against outcome attainment. A practice already inside the Kidney Care Choices model has the reporting habits that arrangement rewards, and the daily data this program produces is what any successor model will score on.

What it takes off this forecast

Three numbers, each smaller than the last, because each one sits on a larger base. Both bars are drawn on one shared dollar scale, so the shaded reduction can be compared directly across them.

1
−20.6% on device supply, the headline code and the one the proposal cuts hardest (99454, $48.12 → $38.21 at the South Carolina locality 01 amount).
2
−9.4% on the remote-monitoring arm, because device supply is only 31% of what this forecast's billing mix puts through that program.
3
−7.2% on the whole service line, because remote monitoring is 75% of it and principal care management moves only −0.6%.
Remote monitoring alone

24-month net reimbursement, CY2026 final versus CY2027 proposed, every code repriced at Palmetto GBA South Carolina locality 01 amounts, non-facility, on this forecast's own billing mix. Enrollment, acceptance and mix held constant. This is the rate change alone.

The code families, side by side

National non-facility amounts from the proposed rule's Addendum B, so the movement can be read without a locality in the way. The repricing above uses South Carolina locality 01 amounts; the two bases do not reconcile to the dollar, by design.

99425Principal care management, each additional 30 minutes (physician)$61.46$59.11−3.8%

The device-supply and short-treatment codes are held to a one-year maximum reduction by section 1848(c)(7) of the Act, which phases any decrease of 20 percent or more over two years. CY2027 is the capped year; the remainder of the crosswalk lands no earlier than CY2028.

None of this is final

The comment period on CMS-1848-P closed September 14, 2026. The final rule publishes in early November 2026 and takes effect January 1, 2027. CoachCare is leading advocacy on the remote-monitoring provisions and will rerun this forecast against the final rates the week they publish.

Why CoachCare for Columbia Nephrology Associates

Built for the Way This Practice Runs

Six reasons this partnership fits Columbia Nephrology specifically, not remote care in general.

athenahealth

We run inside the chart you already use

CoachCare integrates bi-directionally with athenahealth: eligibility flags and enrollment orders leave the chart, and discrete blood-pressure and weight readings, care documentation and claim-ready charges come back into it. One record for the nephrologists across all four offices, one workflow for the billing team, and no second system to learn to start.

Full service

The model that runs without hiring

Enrollment outreach, the care team, device logistics, 24/7 alert triage and billing preparation sit on CoachCare's payroll. The practice inherits a running program the month it turns on, at a 42.2% margin, with no hiring cycle. On-site enrollment is our expense, because telephonic outreach converts about 8% and this panel is worth staffing the clinic for.

Governance

The practice stays in charge

Your nephrologists set the protocols, sign the care plans and make every clinical decision, and claims go out under the group's own entity and NPIs. CoachCare supplies the staff, devices, platform and billing preparation under that governance. It is the operating model an independent group keeps control of.

Payer mix

Most of the panel bills per claim

This is a low Medicare Advantage market, so most of the panel is traditional Medicare and every RPM and PCM code bills fee-for-service, month after month. For the Advantage minority, the statutory floor pays a non-contracted plan no less than original Medicare, with care-management terms confirmed contract by contract. The mix works in the program's favor here.

Service line

One spine under Kidney Care Choices and the panel

The group already carries total-cost accountability through Kidney Care Choices, where broad chronic-care enrollment defends the reconciliation rather than a shortlist. And every hospital discharge across the four offices and fifteen dialysis units opens a transitional-care window. One remote care service line covers both the KCC panel and the post-discharge cohort.

Aligned

Paid as you enroll, no capital, no lock-in

Fees are per active patient per month; there is no capital outlay and no payroll ramp. Because the forecast is set by enrollment pace, throughput is the lever. If the census does not build, CoachCare does not get paid, and the forecast, Disclosures and workbook behind this page are yours to keep either way.

The ask: a working session to validate the Medicare panel against your own chart counts, confirm what the current CKD and hypertension management already covers, scope the athenahealth interface, and set the go-live for the post-discharge cohort.
