Medical Coding AI Training Jobs: Pay and Programs

Who is hiring medical coders for AI training

AI companies building coding and documentation tools need people who know when a code is wrong. These are the coding, chart review and CDI listings we read on 14 November 2026, alphabetically by program, with pay as each program posts it.

"Up to" is a ceiling, not the rate most people earn. micro1's posts did not state a rate in their text on the day we read them; the rate is set per project.

CrowdGen by Appen also runs a healthcare administrators track at up to $90 an hour for reviewing "care workflows, compliance, and operational systems" (CrowdGen). It is not a coding role, but HIM and revenue cycle staff may fit.

What medical AI annotation work for coders involves

The work turns your coding judgment into training data. DataAnnotation asks coders to "Write prompts that test coding accuracy: ICD-10-CM, CPT, and HCPCS assignment, modifiers, and E&M leveling from real clinical documentation" and then fix the model's output (DataAnnotation). Its CDI role probes "present-on-admission and MS-DRG impact" (DataAnnotation).

Inpatient work goes deeper into grouping. micro1's certified inpatient post asks coders to "Identify principal and secondary diagnoses, sequence codes according to guidelines, assign Present on Admission (POA) indicators, and validate MS-DRG assignment" (micro1). Mercor's coders "Evaluate AI-generated clinical notes and summaries against real-world documentation and coding standards" (Mercor).

If you already do chart review jobs or coding audits, this is the same skill pointed at a model instead of a claim. You explain why a code is unsupported, not only which code is right.

CPC, CCS or CIC: which credential the listings want

The AAPC says the CPC "validates a professional's comprehensive knowledge of medical coding across outpatient and physician services" (AAPC). AHIMA describes the CCS as "designed for individuals skilled in classifying medical data from medical records" and "a natural progression for professionals experienced in coding inpatient and outpatient records" (AHIMA).

The listings follow that split. micro1's certified inpatient and records coder posts ask for a CCS or CIC (records also accepts a CPC), while DataAnnotation looks for a CPC or CCS and says no degree is required. Mercor accepts a CCDS, CHC, CCS or CPC but also wants you to be working in coding or CDI now. If you hold only a CPC, the outpatient, professional-fee and general coder roles are the closest fit.

A medical coding side hustle: hours, pay structure and contracts

Most listings ask for a floor of hours. Mercor wants "Availability of at least 10 hours per week", as does micro1's inpatient coder post. That post is paid per task: "experts are paid per completed task that meets the project specifications", with an average handling time of "approximately 1 hour per task" (micro1). Your effective hourly rate depends on how many tasks are signed off.

You work as a contractor, not an employee. Mercor says "You will be engaged as an independent contractor" and pays "weekly on Stripe or Wise" (Mercor). DataAnnotation lists payouts as weekly (DataAnnotation). Taxes are not withheld; see taxes on AI training jobs.

If you code full time for a hospital, payer or vendor, read its outside-work and conflict-of-interest policy before you start. Tell us your credential and country and we'll email you the programs open to you.

Never bring PHI from your coding job

Coders see protected health information every day, and none of it belongs in AI training work. HIPAA says a covered entity or business associate "may not use or disclose protected health information, except as permitted or required" (45 CFR 164.502). Stripping names yourself does not make a record de-identified; 45 CFR 164.514 sets the standard.

Legitimate projects supply their own records. Mercor says the work "will not involve access to confidential or proprietary information from any employer, client, or institution" (Mercor). Do not use your employer's encoder, EHR or grouper logins for a task. micro1's chart reviewer post lists "Access to current ICD-10-CM and ICD-10-PCS code sets, Official Coding Guidelines, and MS-DRG grouper tools" among its preferred qualifications (micro1); if a project needs reference tools, ask what it provides rather than borrowing your employer's licenses.
