Job description

Review inpatient medical records and assign the right codes to help improve AI systems, on your own schedule.

AI companies need inpatient medical coders to test and correct their systems on real hospital records. This project needs coders to read complete inpatient charts, assign diagnosis and procedure codes, and check the MS-DRG assignments. Where a record is unclear, they document the ambiguity and give feedback that helps AI models and coding workflows. This is that work, done remotely around your schedule.

What you'll do

• Review complete inpatient records, from admission notes and operative reports to discharge summaries
• Code each case in ICD-10-CM and ICD-10-PCS, adding Present on Admission indicators and sequencing principal and secondary diagnoses by the guidelines
• Validate the MS-DRG on each case, checking how complications and comorbidities were handled, and flag patient safety indicators and hospital-acquired conditions
• Write up unclear cases and give feedback on how coding workflows can improve and how AI models read records

Why this is worth your time

• Get paid $50–$70 an hour
• Use your inpatient coding skills on real records, from principal diagnosis selection to MS-DRG validation
• Work real cases with UHDDS definitions, the official ICD-10 guidance and AHA's Coding Clinic
• Fully remote and flexible, no fixed shifts, no commute

Who this is for

• An active CIC credential from AAPC (Certified Inpatient Coder), or an active CCS credential from AHIMA (Certified Coding Specialist)
• Hands-on experience coding inpatient records, plus a thorough working knowledge of MS-DRG methodology and the ICD-10-CM and ICD-10-PCS code sets
• Fluent in English and clear in both writing and speech, with up-to-date code sets, the official guidelines and MS-DRG grouper tools on hand
• No AI experience needed.

Pay and details

• $50–$70 per hour, paid hourly as an independent contractor
• Part-time, flexible schedule; fully remote, United States
