- Retrospective Coding
Annova’s retrospective coding services ensure accurate risk adjustment by thoroughly reviewing submitted claims and medical records across various HCC models, including Medicare Advantage (CMS-HCC), ACA (HHS-HCC), and Medicaid (State-Specific HCCs). Our expert coders validate submitted diagnosis codes, confirm alignment with clinical documentation, and suggest edits or deletions for unsupported or incorrect codes, reducing audit risks. Additionally, we identify missed chronic conditions that impact risk scores, ensuring all eligible HCCs are appropriately captured for maximum compliance and reimbursement accuracy. Leveraging AI-assisted coding tools and expert-driven chart reviews, Annova helps payers and providers refine risk scores, close documentation gaps, and enhance coding accuracy, ultimately improving financial and operational performance in risk-adjusted payment models.
