About the Role

Remote billers and coders translate clinical documentation into accurate ICD-10, CPT, and HCPCS codes, ensure annotation guidelines compliance, submit clean claims via EDI, monitor payer adjudication, and resolve denials. Roles may expand into healthcare NLP workflows, including named entity recognition for diagnoses and procedures, OCR-based document verification, and large language model evaluation for coding assistants. Success requires meticulous attention to detail, HIPAA compliance, and coordination across providers, RCM teams, and payers to drive first-pass claim acceptance and accelerate revenue cycle management.

Key Responsibilities

Review charts for medical necessity and documentation completeness; assign ICD-10-CM, CPT, and HCPCS with correct modifiers; validate coding against payer policies; enter charges and submit claims; track clearinghouse rejections; manage denial appeals; perform QA audits to improve training data quality; collaborate on prompt evaluation and model performance improvement for LLM-assisted coding; maintain annotation logs; and provide feedback that strengthens codified guidelines and revenue cycle workflows.

Required Skills & Certifications

Strong knowledge of ICD-10-CM, CPT, HCPCS; familiarity with EHR systems, payer portals, and clearinghouses; understanding of HIPAA and compliance; productivity with claim lifecycle tools; and clear written communication. Certifications such as AAPC CPC/COC or AHIMA CCS/RHIT/RHIA are preferred. Experience with EncoderPro, 3M/Optum encoders, and audit tools is valuable. For AI-related projects, basics of data labeling, QA evaluation, named entity recognition, OCR, and large language model evaluation will help you contribute to healthcare automation initiatives.

Workflows & Tools

Typical workflows include chart abstraction, code assignment, charge entry, EDI claim submission, payer follow-up, denial management, and audit reporting. Tools may include EHRs (Epic, Cerner, athenahealth), encoders (3M, Optum), clearinghouses, payer portals, spreadsheets for reconciliation, and ticketing systems. On AI projects, you may use annotation platforms, guideline validators, and experiment trackers—supporting annotation guidelines compliance, training data quality, and model performance improvement within LLM training pipelines for healthcare NLP and OCR.

Employment Types & Modifiers

Openings on Rex.zone include remote, hybrid, contract, freelance, part-time, and full-time roles, spanning entry-level to senior. Positions appear across domains such as clinical coding, revenue cycle operations, NLP data labeling, computer vision annotation for documents, content safety labeling for PHI, and LLM training projects. Employers include hospitals, physician groups, RCM vendors, BPOs, tech startups, and AI labs. Schedules may be flexible and cross time zones, depending on client coverage needs.

Compensation & Growth

Compensation varies by employer, certification, specialty, productivity, and complexity of charts, with options ranging from hourly to per-claim or project-based contracts. Growth paths include senior coder, auditor, lead biller, team lead, revenue integrity analyst, and AI quality specialist contributing to healthcare NLP and LLM initiatives. Continuous education on coding updates, payer rules, and automation tools enhances career mobility and earning potential.
