Best-in-class cardiology practices outperform average performers on every major claims metric, and the gap adds up to real money. The table below reflects 2026 industry benchmarks drawn from Revenue Synergy client data, AMS Solutions cardiology billing guidance, and MGMA and HFMA benchmarking methodology.
| KPI | Industry Average | Best-in-Class Target | Warning Threshold |
|---|---|---|---|
| Clean Claim Rate | 78–82% | 95%+ | <90% |
| Denial Rate | 10–14% | 3.8% | >10% |
| Days in A/R | 42-55 days | 28-35 days | >40 days |
| Net Collection Rate | 75–80% | 96%+ | <95% |
| A/R Over 90 Days | ~13.5% | under 15% | >15% |
For a practice billing $250,000 per month, an 8% denial rate ties up significant revenue every month. Reducing that rate to 4% can recover substantial revenue over a year. That gap is exactly what the next section explains, starting with why claims get denied in the first place.

Roughly 20–30% of RPM claims are delayed or denied because of documentation, time-tracking, and coding errors. Most of these causes share one trait: they are fixable with automated validation before a claim ever reaches the payer. The table below breaks down the highest-frequency triggers and shows how manual review compares to automated checks for each one.
| Denial Root Cause | CPT Codes Affected | Manual Process Risk | Automated Validation Outcome |
|---|---|---|---|
| Missing device transmission data | 93294–93298, 99454, 99445 | Staff log into OEM portals manually; transmission gaps go undetected until claim rejection | Rhythm360 ingests data via redundant feeds with >99.9% transmissibility; gaps flagged in real time before billing |
| Mismatched CPT/documentation (e.g., 93298 without physician interpretation, 99454 without 16-day threshold) | 93297, 93298, 99454 | Manual chart review misses required interpretation notes or day-count shortfalls | Platform auto-validates day counts and documentation completeness before claim generation |
| Duplicate billing within lookback window | 93294, 93295 (90-day); 93297, 93298 (30-day) | Billing 93295 twice in a 90-day window triggers a CO-18 duplicate denial | Automated billing calendar enforces per-device, per-period submission rules |
| Prior authorization gaps | High-cost imaging, device implants | Prior-auth denials occur in the 15–25% range for cardiology procedures | Auth status checked at scheduling; hard stops prevent service without confirmed authorization |
| Missing patient consent documentation | 99453, 99445, 99457, 99470 | Missing or incomplete consent documentation is a common cause of RPM denials | Enrollment workflow enforces consent capture with audit trail before monitoring begins |
| Insufficient time documentation for management codes | 99457, 99458, 99470 | Generic notes like "reviewed chart" are insufficient; each session needs date, duration, and activity description | Time-tracking module captures date-stamped activity logs automatically within the patient record |
Each denial cause above maps to a specific stage in the claims workflow. Fixing them requires changing how each stage operates, not just adding a check at the end. Here is how manual and automated approaches compare at each of the seven stages.
Practices managing patients with devices from multiple manufacturers face an unavoidable data fragmentation problem. Other platforms in this space include Paceart, Murj, PaceMate, Implicity, Rhythm Management Group, and Octagos. Logging into separate OEM portals for each manufacturer introduces transcription errors, delays billable event identification, and creates audit gaps that expose claims to denial.
Rhythm360 solves this by consolidating all CIED and RPM data into a single vendor-neutral dashboard, which is the change Dr. Gaurav A. Upadhyay at the University of Chicago Medicine pointed to when he said, "We have improved billing and accountability for our patients after the integration." That improvement held up at scale: UCM processed more than 73,000 reports annually through Rhythm360 in 2025, averaging over 18,000 per quarter, without a corresponding rise in billing errors.

| Vendor-neutral data ingestion (API, HL7, XML, PDF via computer vision/OCR) from all major OEMs | Eliminates manual portal logins and transcription errors; ensures complete transmission records for CPT 93294–93298 billing |
| Redundant data feeds with >99.9% transmissibility | Prevents missed billable events from OEM server downtime; maintains uninterrupted data records for 99454/99445 |
| AI-powered alert triage with optional 24/7 CCT oversight | Prioritizes clinically significant events for timely physician review and compliant 93296/93298 billing |
| Bi-directional EHR integration (Epic, Cerner, Athenahealth, eClinicalWorks) | Auto-populates interpretation and report fields; eliminates gaps that trigger CO-50 denials |
| Automated CPT code capture and time-tracking for RPM management codes | Generates date-stamped logs satisfying 99457/99470 requirements; supports 99445/99454 day-count validation |
| Administrative dashboard with real-time compliance and revenue tracking | Surfaces denial trends by reason code; enables correction before claims reach the payer |

Manual workflow improvements take time. They require sequential staff retraining, portal-by-portal reconciliation, and repeated scrubber rule updates. A nine-provider cardiology group that implemented NCCI-aligned front-end edits and dedicated prior-authorization ownership cut its first-pass denial rate from 15.8% to 5.2% and days in A/R from 54 to 31 within two quarters. That timeline assumed real internal investment in process redesign.
Rhythm360's onboarding, including EHR integration, typically finishes in days to a few weeks. Here is how the two approaches compare over 90 days.
Assigning a dedicated denial management owner and a weekly denial scorecard typically cuts denial rates 20–40% within 90 days. Rhythm360 reaches that outcome faster by surfacing denial trends and routing corrective actions automatically, without a dedicated internal analyst. Getting there also depends on staff knowing the 2026 code changes cold, which is where training comes in.
The 2026 CPT code set introduced changes that require active staff education. CMS finalized two new RPM codes effective January 1, 2026: CPT 99445 (device supply for 2–15 days) and CPT 99470 (first 10 minutes of RPM treatment management). These codes are mutually exclusive with their counterparts. Practices must choose between 99445 or 99454 for device supply, and between 99470 or 99457 for treatment management, for each patient in each billing period.
Billing staff need training on four points in particular.
Manual training programs need quarterly updates as CMS issues payment system changes. Rhythm360 embeds CPT validation rules and LCD compliance checks directly into the billing workflow, so staff spend less time tracking regulatory updates between training cycles. That reduced burden is what ultimately shows up in the performance numbers below.
The gap between practices using fragmented manual workflows and those using unified automated platforms keeps growing. Initial claim denials hit 11.8% in 2024, up from 10.2% four years earlier, and 41% of providers now face denial rates of 10% or higher. The 2026 CPT updates for RPM services add complexity and new revenue opportunity that manual processes struggle to capture consistently.
Rhythm360 delivers measurable results: an 80% reduction in critical alert response times and up to a 300% increase in revenue from better CPT code capture and new RPM service lines. These results show up in real-world settings, including at the University of Chicago Medicine, where the report volume noted earlier was matched by improved billing accountability.
Practices that close the gap do it by removing the manual steps that cause errors. Fragmented OEM portal logins, manual day-count tracking, and disconnected documentation get replaced with automated validation that runs at the point of data capture, not after a denial arrives.

Four categories cause most denials. Duplicate billing within the lookback window (billing 93295 twice within 90 days, or 93298 twice within 30 days) triggers automatic CO-18 denials. Missing documentation when billing the technical component of remote interrogation separately under CPT 93296 causes rejections. Device-type mismatches, where the billed code doesn't match the implanted device category, add another layer. Prior authorization gaps on high-cost procedures round out the list and are hard to appeal after the service happens. Automating transmission tracking and pre-submission scrubbing against per-device, per-period rules eliminates most of these before claims reach the payer.
Effective January 1, 2026, CMS added two codes for shorter monitoring periods. CPT 99445 covers device supply for 2–15 days within a 30-day period. CPT 99470 covers the first 10–19 minutes of RPM treatment management, reimbursed at roughly $26. Both are mutually exclusive with their longer-period counterparts (99454 and 99457), so billing both for the same patient in the same month results in denial. Documentation requirements stay strict: device supply codes need specific transmission dates and total monitoring days, and management codes need date-stamped time logs plus evidence of at least one interactive communication per month.
As shown in the benchmark table above, aim for a clean claim rate above 95%, a denial rate below 5%, days in A/R under 40, a net collection rate of 96% or higher, and A/R over 90 days below 15% of total A/R. Practices without strong front-end and documentation controls often run first-pass denial rates of 15–20%, which extends A/R days and cuts net collections. Each denied claim adds 14–21 days to the collection cycle and costs $25–$118 to rework, so prevention costs less than remediation every time.
Separate portals for Medtronic, Boston Scientific, Abbott, Biotronik, and others create data silos that delay transmission verification and introduce transcription errors. Each manual login is a point where transmission gaps can go undetected until a claim gets denied. A vendor-neutral platform consolidates all device data into one dashboard, automates completeness checks, and links each verified transmission to its CPT documentation. This removes the manual reconciliation step that most often causes day-count errors on 99454 and 99445 claims, and ensures interpretation records required for 93296 and 93298 exist before submission.
An enrollment packet needs an initiating visit record, a medical necessity statement tied to a qualifying chronic condition like heart failure or hypertension, a dated consent note explaining Part B coinsurance and monitoring expectations, and a device provisioning record showing device type, connection method, and supply date. For management codes, documentation must show the date and substance of at least one interactive communication with the patient or caregiver each month. Data review alone doesn't satisfy this. Written clinical protocols defining device strategy, alert thresholds, and escalation actions for each condition are the strongest defense against medical necessity denials and OIG scrutiny. Consent must be documented before billing starts and stay retrievable for audits.
