Medical Coder Expert

Certified medical coders to build the coding and documentation scenarios frontier AI labs use to test model judgment.

AfterQuery builds the expert evaluation data that frontier AI labs use to measure and improve their models. We're hiring certified medical coders as contractors to author and grade the coding and documentation scenarios those evaluations run on.

What you'll actually do

• Author realistic coding scenarios from chart documentation through final code set
• Write reference answers with the guideline citations behind each code choice
• Grade model output for coding accuracy and compliance risk
• Flag code sets that look clean but would fail an audit

Who this is for

• CPC (AAPC) or CCS (AHIMA) certification in good standing
• 2+ years of production coding experience
• Depth in ICD-10-CM, CPT, and HCPCS with real chart experience
• You can explain code selection clearly enough for another coder to follow it

Contract and pay

• $65 to $95/hr, paid weekly via Stripe. Your rate is set from your experience, not negotiated down after you start.
• Remote and fully async. No fixed hours.
• Minimum 10 hours per week, no maximum. Scale up or down week to week.
• No screen recording, no keystroke monitoring, no idle timers.
• Independent contractor. Ongoing project work rather than single task batches.

How our hiring process works

• Apply at /apply/medical-coder-expert. About five minutes. Resume plus a few structured questions.
• Resume review. Every application gets read against a published rubric and gets a decision.
• Written assessment. You may be asked to take a written assessment for further placement.
• Onboarding. Sign the contractor agreement, connect Stripe, and get platform access.
• Project match. You're matched to live work in your specialty, usually within a week of onboarding. About AfterQuery
