What this actually is
You design problems that stump current AI models, evaluate AI reasoning against the correct answer, write rubrics, and provide expert feedback. Often the highest-paid category because the expertise pool is small. The platform title (Medical Coder) reflects the rate band and the expertise required, not the day-to-day work.

Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required. Your domain knowledge is what matters.
Scope of Work
• Annotate and review outpatient medical records (physician office, clinic, ambulatory surgery, and hospital outpatient encounters), ensuring accurate assignment of ICD-10-CM and CPT/HCPCS codes based on documentation.
• Apply Evaluation & Management (E&M) leveling to outpatient visits using official guidelines (medical decision making or total time) to validate and enrich datasets.
• Apply outpatient-specific coding conventions, including diagnosis coding guidelines for outpatient services, modifier usage, medical necessity, and linking diagnoses to procedures.
• Collaborate with project stakeholders via written and verbal communication to clarify requirements and resolve ambiguities in clinical documentation.
• Provide high-quality feedback on coding guidelines and edge cases to improve project workflows and model understanding.
Preferred Qualifications
• Active AAPC Certified Professional Coder (CPC) certification is required.
• Comprehensive understanding of ICD-10-CM and CPT coding systems and outpatient E&M leveling guidelines.
• Hands-on experience coding in outpatient settings (e.g., primary care, specialty clinics, ambulatory surgery centers, outpatient hospital departments).
• Experience with diverse clinical documentation types and associated coding challenges, such as office visit notes, procedure notes, and operative reports.
• Proficiency with both written and verbal communication, with a strong attention to clarity and detail.
• Access to up-to-date official ICD-10-CM, CPT, and HCPCS Level II coding books, as well as E&M guidelines.

Is micro1 legit? Our review
A real US company that pays experts in USD through Deel twice a month. The hard part is getting from the Zara AI interview to paid work. Pay, who can join, and how Korean visa and tax rules apply.
