Job description

We are looking for US-based experienced, certified HCC risk adjustment coders to join our contractor network. You will review medical records, validate AI-suggested diagnoses, assign ICD-10-CM codes, and document MEAT evidence per CMS V28 model standards — all within our purpose-built coder workbench platform.

This is a remote, per-chart or hourly contract engagement. Volume will scale as our client pipeline grows; we are building the bench now so we can move quickly when engagements launch.

What You’ll Do

• Review outpatient and ambulatory encounter documentation for Medicare Advantage members
• Validate AI-suggested diagnosis codes and manually add any missed diagnoses
• Document MEAT (Monitor / Evaluate / Assess / Treat) evidence per code, referencing specific source text in the chart
• Flag ambiguous documentation, legibility issues, or charts requiring escalation
• Participate in over-read / inter-rater reliability QA process
• Work within CMS V28 HCC model mapping standards

Requirements

• Active AAPC CRC (Certified Risk Adjustment Coder) credential — required, no exceptions
• Minimum 2 years of HCC risk adjustment coding experience
• Familiarity with CMS V28 model (knowledge of V24 → V28 transition strongly preferred)
• US-based; must be authorized to work in the US
• Own equipment: reliable computer and high-speed internet connection
• Comfortable working in a digital platform environment (training provided on our specific tooling)
• High attention to detail and commitment to coding accuracy and audit defensibility

Compensation

• Competitive per-chart or hourly rate (~30-35USD/hr), commensurate with experience
• Rates discussed individually during onboarding

What to Expect

• Fully remote, flexible schedule
• Identity verification required as part of onboarding (credential check, KYC process — required for PHI access compliance)
• All contractors handling PHI will be required to sign a Business Associate Agreement (BAA) as part of onboarding.
