About the Role

Work-from-home medical coders on Rex.zone assign accurate ICD-10-CM/PCS, CPT/HCPCS, DRG, and HCC codes while contributing to healthcare AI initiatives. You will translate clinical documentation into standardized codes, validate DRGs and risk adjustment, and participate in data labeling, named entity recognition, RLHF for clinical coding assistants, and prompt evaluation to strengthen LLM training pipelines and clinical NLP models.

Key Responsibilities

Perform chart abstraction, E/M leveling, DRG validation, HCC capture, and audit-ready rationales; label entities (diagnoses, procedures, medications, SNOMED CT/UMLS concepts), map documentation to HL7 FHIR resources, classify document types, and assist with PHI de-identification for content safety labeling; execute QA evaluation, write and refine annotation guidelines, review edge cases, and provide coder feedback loops that drive model performance improvement.

Qualifications & Skills

CPC, CCS, CRC, RHIT/RHIA or equivalent credentials; strong ICD-10-CM/PCS and CPT/HCPCS proficiency; experience with payer/provider workflows, NCD/LCD policies, and E/M rules; familiarity with EHR systems (Epic, Cerner) and coding tools (3M, Optum); understanding of HIPAA, PHI handling, and audit practices; exposure to data labeling, named entity recognition, RLHF, and large language model evaluation; clear written rationales and annotation guidelines compliance.

Domains & Projects

NLP for clinical notes, computer vision for scanned records and claims attachments, LLM training pipelines for coding assistance, content safety labeling for PHI/PII, payer risk adjustment analytics, provider revenue cycle integrity, and multi-specialty coding (inpatient, outpatient, pro-fee, anesthesia, radiology, surgical subspecialties).

Employment Types & Modifiers

Remote-first roles across contract, freelance, full-time, part-time, and temp-to-hire; openings for entry-level, mid-level, and senior coders and auditors; opportunities with AI labs, tech startups, health systems, insurers, BPOs, and annotation vendors; projects spanning NLP, computer vision, content safety, and LLM training.

Compensation & Benefits

Competitive hourly or per-chart rates depending on specialty, credentials, and geography; performance bonuses tied to accuracy and throughput; benefits for eligible full-time roles may include healthcare, paid time off, and remote work stipends. Compensation varies by employer, country, and project scope listed on Rex.zone.

Tools & Tech Stack

EHR platforms (Epic, Cerner), coding software (3M, Optum), secure VPNs, ticketing systems (Jira), version control for guidelines, and annotation platforms (Label Studio, Prodigy). Projects may involve HL7/FHIR resources, ICD-10-CM/PCS, CPT/HCPCS, SNOMED CT/UMLS, and LLM-based prompt evaluation workflows.

Workflow & Quality

Follow structured annotation guidelines and coding policies; achieve high inter-rater agreement and training data quality; leverage blind review and audits; provide corrective feedback that leads to model performance improvement; participate in large language model evaluation, prompt testing, and RLHF cycles to improve clinical coding assistants while maintaining annotation guidelines compliance.

Compliance & Privacy

Operate under HIPAA, SOC 2, and client security protocols; use approved devices, secure VPNs, and DLP tools; handle PHI/PII with least-privilege access; document rationales for audit trails; adhere to payer policy updates and regulatory changes across specialties and jurisdictions.
