Medical Coding (ICD-10/CPT/HCPCS) roles at Rex.zone connect remote, entry-level candidates with paid chart review and coding workflows while also supporting AI/ML training pipelines. As a search-recognizable entity, medical coders standardize clinical documentation, improve training data quality, and participate in QA evaluation for clinical NLP, named entity recognition, and large language model evaluation. No experience? We provide onboarding, annotation guidelines, and supervised practice so you can start with entry-level remote work and grow to senior, contract, freelance, or full-time paths. Apply on Rex.zone to discover medical coding jobs that span provider revenue cycle tasks and AI labs, tech startups, BPOs, and annotation vendors.
Remote medical coders read clinical notes, assign accurate ICD-10-CM, CPT, and HCPCS codes, and support revenue cycle integrity for providers and payers. On Rex.zone, you’ll also collaborate with AI teams to validate model-generated codes, strengthen annotation guidelines compliance, and contribute to training data quality for clinical NLP and LLM training pipelines.
Extract diagnoses and procedures from EHR documentation; assign ICD-10, CPT, HCPCS; ensure medical necessity and payer compliance; perform QA review and audits; assist with de-identification and PHI-safe workflows; evaluate model performance improvement through error analysis; participate in prompt evaluation and named entity recognition tasks; document edge cases and escalate ambiguous charts.
Strong attention to detail, reading comprehension, basic medical terminology and anatomy, ability to follow AHA/AMA guidelines, familiarity with E/M levels and modifiers, spreadsheet proficiency, and clear written communication. Entry-level applicants with no experience are welcome; training and supervised practice are provided. Certifications (AAPC CPC, AHIMA CCA) are a plus but not mandatory.
Use EHR chart viewers and encoders (e.g., 3M 360 Encompass, Optum EncoderPro), payer policies, LCD/NCD references, and internal QA checklists. Follow double-blind audit, peer review, and reconciliation processes. In AI workflows, contribute to RLHF-style review, dataset curation, annotation guideline updates, and large language model evaluation to ensure compliant coding outputs.
Opportunities across remote, contract, freelance, full-time, part-time, entry-level, and senior tracks. Roles include production coding, audit, denial management, quality assurance, and clinical NLP annotation. Availability spans healthcare providers, payers, AI labs, tech startups, BPOs, and annotation vendors on Rex.zone.
Collaborate with teams in NLP, computer vision annotation (e.g., reading scanned charts), content safety labeling for PHI handling, data labeling for ICD-10/CPT datasets, QA evaluation, prompt evaluation for coding assistants, and LLM training pipelines. Your domain knowledge directly supports model performance improvement and compliant automation.
Start in entry-level chart coding and progress to auditor, team lead, or AI annotation specialist. We support certification paths (AAPC/AHIMA), specialty coding (ED, inpatient, outpatient, surgical), DRG assignment, risk adjustment, and advanced QA roles. Document your wins, pass QA targets, and access senior and mentor tracks on Rex.zone.
Competitive pay structures by chart, hour, or project; flexible schedules; remote-first tooling; and learning tracks with supervised feedback. Compensation varies by specialty, complexity, and employer type (providers, AI labs, tech startups, BPOs, annotation vendors). Performance-based bonuses may apply to QA and audit roles.
Create a Rex.zone profile, select Medical Coding, complete the onboarding quiz and sample charts, and choose roles that match your availability—remote, contract, freelance, full-time, entry-level, or senior. Our matching engine connects you with healthcare organizations and AI teams needing compliant coders and annotation specialists.
Yes. Entry-level applicants are welcome. Rex.zone provides guided onboarding, practice charts, and QA-reviewed feedback to help you start earning as you learn.
Certification is not required for entry-level roles but is preferred. We support CPC/CCA preparation and offer pathways to advance into auditor and senior roles.
You’ll access PHI-safe portals, review de-identified or secured charts, code per ICD-10/CPT/HCPCS, submit for QA, resolve feedback, and track productivity metrics in Rex.zone.
Coders label clinical data, validate model-generated codes, perform QA evaluation, assist with named entity recognition, and contribute to RLHF-style reviews for LLM training pipelines.
Remote contract, freelance, part-time, and full-time roles are available across healthcare providers, payers, AI labs, tech startups, BPOs, and annotation vendors.
Common tools include EHR viewers, encoders (3M/Optum), guideline repositories, QA dashboards, and collaboration platforms integrated with Rex.zone.
Rates depend on chart volume, specialty complexity, accuracy, and role type (production, QA, audit, annotation). Some projects offer per-chart pay, others hourly.
Rex.zone supports global talent. Some roles require familiarity with US-specific coding guidelines and HIPAA; others are international with local standards.
