About the Role
Medical Billing and Coding Specialists interpret clinical documentation, assign ICD-10-CM, CPT, and HCPCS codes, prepare CMS-1500/UB-04 claims, and manage EDI X12 837/835 transactions. You will collaborate with clinicians, payers, and RCM teams to ensure coding accuracy, claim scrubbing, denial management, and AR follow-up. On Rex.zone, some employers pair traditional RCM tasks with AI workflows—LLM-assisted coding review, training data quality checks, annotation guidelines compliance, and large language model evaluation to improve model performance.
