A risk adjustment tool is software that helps healthcare organizations — primarily ACOs, health plans, and value-based care providers — accurately identify, document, and capture patient diagnoses that affect reimbursement under CMS risk adjustment models like CMS-HCC and HHS-HCC.

The tool works by analyzing patient data from EHRs, claims, labs, and prior encounters to surface Hierarchical Condition Categories (HCCs) that should be documented at each annual visit. Each HCC adds to a patient's Risk Adjustment Factor (RAF) score, which CMS uses to calculate how much the plan or ACO is paid to manage that patient's care. A higher, more accurate RAF score means more accurate reimbursement — not overpayment, but fair payment for the actual complexity of your patient population.

The most effective risk adjustment tools operate prospectively — before and during the patient visit — rather than retrospectively through post-visit chart review.

A retrospective risk adjustment tool reviews charts and claims data after patient visits have already occurred. Coding teams or external vendors identify gaps in documentation and attempt to capture missed HCCs through addenda or queries to the treating physician. The fundamental limitation: the encounter window has closed. Many HCC opportunities cannot legally be captured after the fact, and those that can require additional physician time and carry higher audit risk.

A prospective risk adjustment tool — like Persivia CareSpace® — operates before and during the visit. AI analyzes the longitudinal patient record 24 hours before each encounter and surfaces suspected undocumented conditions directly to the physician inside their EHR workflow. The physician documents in real time, the code is validated automatically against MEAT criteria, and the visit itself becomes the capture event.

The revenue difference is compounding: missed annual HCCs cannot be recovered retroactively, so every year a retrospective tool is in place is another year of permanently lost revenue.

CMS V28 is the most significant recalibration of the HCC risk adjustment model in over a decade. It revised condition category mappings, updated RAF weights across hundreds of diagnoses, and introduced a phased transition that affects how ACOs and MA plans calculate expected revenue. Organizations relying on older risk adjustment tools — or tools that haven't been updated — risk using inaccurate condition mappings and miscalculating their RAF scores as the V28 transition completes.

Persivia CareSpace® has V28 built directly into the AI and documentation engine: updated condition mappings, revised RAF weights, and phased-in scoring logic are applied automatically to every encounter. Physicians receive prompts that already reflect V28 category changes — there's no manual configuration required and no risk of applying deprecated ICD-10 mappings.

Physician burnout from documentation is one of the most consistent complaints in value-based care — and most risk adjustment tools make it worse, not better. Retrospective tools generate post-visit query volumes that force physicians to revisit closed encounters, often for conditions they documented two months ago.

Persivia's approach inverts this. CareTrak® embeds HCC prompts directly inside the physician's existing EHR interface — no separate portal, no post-visit queue. Prompts are context-aware and driven by NLP analysis of the patient's longitudinal record, so the physician sees only relevant, evidence-supported HCC suggestions rather than a generic checklist. One-click documentation and automated MEAT-criteria validation mean the average time spent on HCC-related documentation drops by up to 50% — 30 minutes per physician per day returned to patient care.

Yes — RADV audit readiness is a core design principle of CareSpace®, not a feature added after the fact. Every HCC documented through Persivia's risk adjustment tool is automatically validated against MEAT criteria (Monitored, Evaluated, Assessed/Addressed, Treated) and linked to supporting evidence from the patient's clinical record. This creates an unbroken, auditable documentation chain from the original clinical encounter to the submitted code.

This matters now more than ever: CMS expanded RADV audits from 60 contracts to all 550 eligible Medicare Advantage contracts, and increased its audit workforce from 40 to 2,000 coders. Organizations without audit-ready documentation are facing real recoupment risk — CMS has historically recovered over $4 billion through audit programs. Persivia's documentation workflow ensures that every code submitted is defensible on its own terms, eliminating both undercoding revenue loss and overcoding recoupment exposure.
