Why weight is the vital sign that predicts everything
Fluid accumulation shows up on the scale
3–7 days before symptoms appear.
Based on published clinical evidence on CHF readmission and weight-based monitoring. Revenue estimates are illustrative and vary by payer mix.
Simple enrolment
From discharge to daily
monitoring in under a week.
The highest-risk window for CHF patients is the 30 days after discharge. Ziva closes that gap - your team refers the patient, and a connected scale is at their door before the first post-discharge visit.
1
Refer at discharge or next visit
Enrol directly from the Ziva portal or your EHR. Select the CHF protocol and set the patient's target weight range. Takes under two minutes.
2
Connected scale ships to their door
A Bluetooth-enabled scale arrives pre-paired to the Ziva app. Isabella walks the patient through their first weigh-in in under 5 minutes - no clinic visit needed.
3
Daily weight flows to your dashboard
Every morning weigh-in populates the patient's trend chart. Threshold breaches alert your team immediately - not at the next scheduled visit.
4
Isabella coaches daily self-management
Sodium limits, fluid restrictions, activity guidance, and medication reminders - delivered each day, within the parameters your team sets.
5
Billing documentation generated
RPM-qualifying weight data tracked automatically. Month-end billing summary ready for your billing team to submit.

Weight monitoring & alerts
See fluid accumulation
days before a readmission.
By the time a CHF patient feels short of breath, they may already have litres of excess fluid. Daily weight is the earliest, most reliable signal - and Ziva captures it every morning, compares it to the patient's established dry weight, and alerts your team the moment a threshold is crossed.
✓Per-patient alert thresholds — set to your protocol (typically 2 lb/24h or 5 lb/7 days)
✓Dry weight baseline locked per discharge or clinical review — drift detected automatically
✓Symptom correlation — shortness of breath, oedema, and activity level logged alongside weight
✓Medication adherence tracked — diuretic and ACE-inhibitor missed doses flagged and correlated with weight spikes
✓Alert escalation documented in EHR — critical thresholds generate clinical notes posted to the patient record
✓Missing weigh-in flagged before the day ends — automated patient reminder sent, then team notified if still absent
Default alert rules — adjustable per patient
Daily gain≥ 2 lb in 24h → Urgent alert
Weekly gain≥ 5 lb in 7 days → Watch alert
No weigh-inBefore 10am → Patient reminder; by noon → Team flag

AI patient coaching
Your CHF protocol,
delivered to every patient. Every morning.
CHF self-management - daily weighing, sodium restriction, fluid limits, and medication adherence - is what keeps patients out of hospital. Isabella delivers that coaching consistently, in plain language, grounded in each patient's own data. When weight or symptoms escalate beyond coaching scope, Isabella alerts your clinical team.
✓Daily weigh-in prompt with trend context — "You're up 1.4 lb from yesterday; your care team's threshold is 2 lb"
✓Sodium tracking — your team sets the daily limit; Isabella coaches each meal and flags high-sodium foods
✓Fluid restriction reminders, calibrated to the patient's prescribed daily limit
✓Diuretic and guideline-directed medication reminders, with adherence logged to your dashboard
✓Symptom check-ins — breathlessness, swelling, fatigue — with automatic escalation when signals converge
Morning coaching — Bernard T.*
Isabella → Patient
"Good morning, Bernard. Today's weigh-in: 184.2 lb — up 1.8 lb from yesterday. You're close to your 2 lb alert threshold. Your team recommends limiting fluids to 1.5 L today and avoiding canned foods. Let me know if you notice any ankle swelling."
Sodium coaching — Patricia W.*
Isabella → Patient
"Lunch idea: the turkey sandwich you had last Tuesday had 890mg of sodium — most of it in the deli meat. Try a homemade option with roast chicken instead, which cuts that to under 300mg and keeps you well within your 1,500mg daily limit."
Escalation → Dr. Patel's team
Isabella → Provider alert
"Dorothy H.* has gained 4.2 lb in 72 hours. She reports ankle oedema and reduced stair tolerance. Last diuretic dose 36h ago - she mentioned side effects. Weight trend and symptom pattern indicate likely decompensation. Flagging for urgent clinical review."
Patient engagement
Will CHF patients weigh in every day?
Here's what drives it.
The clinical evidence for daily weighing in CHF is unambiguous - but adherence collapses without support. Isabella's morning prompts, immediate feedback, and streak tracking turn a daily chore into a habit. Most Ziva CHF patients hit the 16+ readings per month needed for RPM billing within the first two weeks.
16+
Readings per month
The RPM billing threshold. Isabella's morning weigh-in prompts and streak tracking maintain daily engagement - meeting the requirement month after month.
5 min
Scale setup time
Isabella walks each patient through their first weigh-in in the app. Step on the scale, value syncs automatically - no manual entry, no complex setup.
Every day
Isabella coaching
Personalised coaching grounded in that morning's weight, yesterday's sodium intake, and current medication schedule - not generic health tips.

RPM & CCM billing
CHF patients qualify for
both RPM and CCM billing.
Medicare and most commercial insurers reimburse Remote Patient Monitoring (RPM) and Chronic Care Management (CCM) separately - and CHF patients with comorbidities almost universally qualify for both. Ziva tracks all qualifying data and generates documentation automatically.
RPM — Remote Patient Monitoring
99453Device setup (one-time)~$19
99454Device supply, 16+ days/month~$65/mo
99457Management, first 20 min/month~$51/mo
99458Each additional 20 min~$41/mo
CCM — Chronic Care Management
For patients with 2+ chronic conditions (CHF + hypertension, diabetes, CKD, AFib)
99490Standard CCM, first 20 min/month~$62/mo
99439Standard CCM, each additional 20 min~$47/mo
99487Complex CCM, first 60 min/month~$130/mo
99489Complex CCM, each additional 30 min~$67/mo
RPM and CCM can be billed together in the same month. Approximate Medicare rates. Commercial rates vary. Consult your billing team and compliance officer.

Questions
Provider FAQ
Practice onboarding typically takes 2–3 weeks from contract signing to first patients enrolled. This covers EHR integration, CHF protocol configuration, a 1-hour staff training, and your first device orders. Practices with an active post-discharge CHF programme often enrol their first cohort in week one of go-live.
A validated digital scale. Depending on the device, it ships either with a cellular gateway already synced with Ziva - readings transmit automatically, no pairing or smartphone needed - or as a Bluetooth device the patient connects to the Ziva app once during setup. Device cost and fulfilment are included in the platform fee. Isabella guides each patient through their first weigh-in in the app - no clinic visit or staff time needed. Scales ship within 48h of enrolment.
Yes - thresholds are configurable per patient. The platform defaults to the standard clinical rules (2 lb in 24h, 5 lb in 7 days) but these can be adjusted based on the patient's baseline, functional status, and care plan. Alert routing is also configurable: by severity level, clinician role, or time of day.
Ziva integrates with Epic, Cerner, athenahealth, eClinicalWorks, MEDITECH, NextGen, PointClickCare, AdvancedMD, Allscripts, WellSky, and more via HL7 FHIR R4. For systems not listed, Ziva provides a standalone portal and CSV export. Contact our team to discuss your environment before the demo.
Ziva automatically tracks device supply days (CPT 99454), clinical time spent (CPT 99457/99458), and consent records. A billing-ready summary is generated per patient per code at month-end for your billing team to submit. Ziva does not submit claims directly. The daily weight data also satisfies RPM's requirement for physiological data transmission on 16+ days per month. Review with your compliance officer before go-live.
