Is there a free HCC encoder?

Yes. The HCC Buddy ICD-10-CM encoder is free to start with three code lookups per day, no card required. Each lookup shows current CY2026 V28 mapping status for non-PACE Medicare Advantage, a separate historical PY2025 V24 reference, billable status, MEAT guidance, and current RAF review status. HCC Buddy never stores, logs, or transmits PHI.

What is the best HCC coder tool for risk adjustment?

A good HCC coder tool shows mapping status for the current CMS-HCC model, keeps historical mappings clearly labeled, and surfaces MEAT guidance. HCC Buddy shows current FY2026 ICD-10-CM and CY2026 V28 mapping, while historical PY2025 V24 stays reference-only. The RAF Calculator supports CMS-HCC V28 PY2026 with complete member context and shows no score unless every source and calculation check passes.

What is the RAF status in the free HCC encoder?

Every lookup shows the HCC category and V28 mapping status. Reference coefficients, when shown, use the official member segment labels: CNA (Community Non-Dual Aged), CND (Community Non-Dual Disabled), CFA (Community Full Benefit Dual Aged), CFD (Community Full Benefit Dual Disabled), CPA (Community Partial Benefit Dual Aged), CPD (Community Partial Benefit Dual Disabled), and INS (Institutional). A code-level coefficient is not a member score. The RAF Calculator applies hierarchy, cleanup, interactions, and complete member context for CMS-HCC V28 PY2026, then withholds the score if a required check does not pass.

Is the HCC Buddy encoder a Codify alternative?

Yes. Coders use HCC Buddy to check current CY2026 V28 mapping status, review a separate historical PY2025 V24 reference and MEAT guidance, and work inside the EMR with a Chrome extension. Founding access is $19.99 per month, then $29.99, with a free anonymous demo first.

Buddy Documentation Tip

HCC Buddy guidance

Provider documentation clearly stating COPD or chronic obstructive pulmonary disease

Current symptom status such as dyspnea, cough, sputum production, or exercise tolerance

Current medications such as bronchodilators, inhaled corticosteroids, or oxygen therapy

MEAT Support

Audit Caution

HCC Buddy guidance

Do not use J44.9 when documentation supports acute exacerbation, acute lower respiratory infection, or a more specific COPD type.

Common Mistakes

HCC Buddy guidance

J44.1, COPD with acute exacerbation, when acute worsening is documented

J44.0, COPD with acute lower respiratory infection, when a concurrent acute infection is documented

Current V28 Mapping and Historical V24 Reference

See current CY2026 V28 mapping status for non-PACE Medicare Advantage with the historical PY2025 V24 reference kept separate. PACE has separate model blends. Coefficients stay labeled by member segment.
