About the Role

Entry-level medical billing and coding roles focus on translating clinical documentation into ICD-10-CM diagnoses, CPT procedure codes, and HCPCS Level II supplies, preparing CMS-1500/UB-04 claims, posting payments (835), and resolving denials. You’ll support revenue cycle management (RCM) accuracy, payer policy compliance, and clean claim submission, while collaborating with teams using NLP-assisted coding and AI tools that depend on precise labels for large language model evaluation and automation.

Key Responsibilities

Review charts and encounter notes, assign codes per official guidelines, validate coding accuracy, perform charge entry and claim scrubbing, submit EDI 837 transactions, track rejections, support denial management and appeals, reconcile EOBs, maintain HIPAA compliance, and document workflows for training data quality. Contribute to clinical NLP labeling standards and annotation guidelines compliance that drive model performance improvement in claim automation.

Required Skills

Foundation in medical terminology, anatomy, and physiology; familiarity with ICD-10-CM, CPT, HCPCS; attention to detail; HIPAA awareness; basic EHR navigation; clear written communication; beginner Excel/Google Sheets skills; willingness to learn payer rules and X12/EDI formats. Exposure to NLP-assisted coding, clinical named entity recognition, and LLM training pipelines is a plus but not required for entry-level roles.

Work Modalities & Modifiers

Openings include remote, contract, freelance, and full-time positions across entry-level and pathways to senior roles. Domain types span provider RCM, clinical NLP, computer vision for EOB document processing, content safety for PHI handling, and LLM training in healthcare. Employers include hospitals, multi-specialty clinics, AI labs, tech startups, BPOs, and annotation vendors operating on or hiring through Rex.zone.

Tools & Technologies

EHR systems (e.g., Epic, Cerner, Athenahealth), coding software (3M, Optum), clearinghouses (Availity), payer portals, ANSI X12/EDI 837/835, CMS-1500/UB-04 forms, claim scrubbers, ticketing/CRM, spreadsheets, and NLP-assisted coding systems. Computer vision/OCR tools may support EOB extraction and document classification in AI-enabled RCM workflows.

Career Growth

Advance from junior coder/biller to certified roles (AAPC CPC/CPC-A, AHIMA CCA/CCS), denial prevention specialist, auditor, RCM analyst, compliance officer, or HIM professional. Experience with clinical NLP labeling, data quality, and guideline governance can open paths into health informatics and AI operations within coding automation teams.

Compensation & Benefits

Compensation varies by region and employer type; entry-level roles commonly range from approximately USD $16–22 per hour, with potential certification reimbursement, training stipends, and health benefits. Contract and freelance rates may differ based on specialty, volume, and turnaround expectations. Rex.zone postings include clear pay details and work arrangement specifics.
