CodaFend is on-premise AI software that automates HCC chart review, MEAT evidence extraction, and RADV audit preparation for Medicare Advantage plans — with all PHI kept inside your network. RafCite™ handles chart review. RuleBrief delivers regulatory intelligence. Both are CodaFend products.
Who We Are
CodaFend is the operating brand of Cast Rock Innovation L.L.C. d/b/a Cast Net Technology, a technology company specializing in compliance-critical software for regulated industries.
Our work sits at the intersection of healthcare administration, regulatory compliance, and applied artificial intelligence. We build software for organizations where documentation accuracy, audit defensibility, and regulatory adherence are operational necessities — not afterthoughts.
CodaFend was founded by a team with direct, hands-on experience inside Medicare Advantage operations — including professionals who have worked on CMS RADV audit responses, risk adjustment data validation workflows, and compliance remediation programs at health plans. That operational background informs every design decision: we understand what coders, auditors, and compliance officers need from software because we have been those people.
Company Profile
Sectors
Our work spans regulated environments where precision, defensibility, and timeliness are mission-critical.
Organizations managing CMS risk-adjustment programs face continuous documentation requirements and periodic RADV audit exposure. We build tools that help compliance and coding teams maintain defensible, audit-ready records.
RADV HCC validation →From physician groups to managed care organizations, healthcare administrators operate under overlapping federal and state regulatory frameworks. Our software brings structure and traceability to documentation-heavy workflows.
Chart review software →Businesses with 5–200 employees face the same regulatory obligations as large enterprises but without dedicated compliance staff. We build products that deliver professional-grade regulatory intelligence to operators who need clarity, not complexity.
Companies operating across state lines face fragmented, rapidly-changing regulatory requirements from dozens of agencies simultaneously. Our monitoring tools surface what's relevant, when it matters, for the specific jurisdictions where a business operates.
What We Build
CodaFend products for Medicare Advantage compliance and regulatory intelligence — built for organizations where accuracy is not optional.
A CodaFend Product · Chart Review Platform
Purpose-built for Medicare Advantage plans. Reviews HCC documentation for CMS RADV audit readiness — under 5 minutes per chart versus 3–4 hours manually. All AI inference runs on your own servers. Zero PHI ever leaves your network.
Unlike cloud-based review services, RafCite™ carries no per-chart consumption cost and requires no data sharing agreement with a third-party AI vendor.
Metrics from internal validation on held-out charts not used in training. Independent clinical review available upon request.
Early-access engagements are limited. Current availability: accepting pilot inquiries for Q2 2026.
A CodaFend Product · Regulatory Intelligence
rulebrief.comRuleBrief monitors 50+ federal and state regulatory sources daily and delivers a personalized, plain-English brief every week — with specific action checklists filtered to your industry, state, and business size. Built for operators who cannot afford to miss a regulatory change but don't have dedicated compliance staff.
The Workflow
From chart upload to reviewer-ready report — entirely on your infrastructure.
Upload PDFs on your internal network. All document processing happens inside your infrastructure — nothing is transmitted externally. Supports batch ingestion for high-volume review cycles. Zero PHI egress →
The platform evaluates each HCC against MEAT criteria — Monitoring, Evaluation, Assessment, Treatment. Evidence is pinned to the exact source sentence in the chart, not interpolated or summarized. MEAT extraction →
A structured report flags each HCC as supported, unsupported, or uncertain — with citations to source sentences. Your coder or auditor makes the final determination. The platform assists; it does not replace clinical judgment. Audit readiness →
How We Work
Three principles that govern every product we ship.
Compliance software must be accurate. We build systems that verify claims against source documents, flag uncertainty explicitly, and never overstate confidence.
Our software assists decision-making; it does not replace it. Every output is designed to be reviewed, questioned, and acted on by a qualified professional.
Everything we ship is designed with the assumption that it will be examined by a regulator. Traceability, documentation, and evidence chains are not features — they are requirements.
