About the Role

You will review clinical documentation, assign accurate ICD-10-CM, CPT, HCPCS, and DRG codes, resolve claim edits, and collaborate with providers on queries to support compliant revenue cycle management. Many roles extend into clinical NLP annotation—mapping entities like diagnoses, procedures, and modifiers—and validating model outputs for large language model evaluation within healthcare automation.

Core Workflows

Typical workflows include professional and facility coding, E/M leveling, HCC risk adjustment, denial management, payer policy review, and audit remediation. In AI contexts, you may perform dataset curation, annotation guidelines compliance checks, QA evaluation on labeled notes, prompt evaluation for coder-assist tools, and feedback loops that drive model performance improvement and training data quality.

AI/ML Integration

Healthcare coding knowledge powers LLM training pipelines and RLHF: your decisions become supervised signals for named entity recognition, code prediction, and documentation compliance models. Roles may include computer vision annotation on forms and charts, PHI de-identification for content safety labeling, and structured feedback to improve classifiers and generative assistants used by AI labs and annotation vendors.

Required Skills

Strong command of ICD-10-CM, CPT, HCPCS, DRG, E/M and payer rules; experience with EHRs, encoders, and clearinghouses; accuracy, compliance mindset, and HIPAA awareness. For AI-aligned roles: familiarity with data labeling workflows, clinical NER concepts, QA evaluation processes, guideline authoring, and basic prompt evaluation for LLM-assisted coding. Certifications like CPC, CCS, RHIT, or COC are preferred.

Compensation & Engagement Types

Openings span remote contract, freelance, and full-time employment. Compensation varies by specialty and seniority; project-based rates for annotation work and competitive salaries for coding and audit roles. Senior positions may include QA lead or guideline authoring responsibilities; entry-level roles focus on production coding and structured labeling.

Employers & Domains

Find opportunities with AI labs, tech startups building coder-assist tools, BPOs scaling revenue cycle operations, and specialized annotation vendors. Domain coverage includes NLP (clinical notes, NER), computer vision (scanned forms, charts), content safety (PHI redaction), and LLM training for code suggestion, query assistance, and audit support.

Frequently Asked Questions

  • Q: What is a remote medical billing and coding job on Rex.zone?

    It’s a role where certified or experienced coders work from anywhere to assign ICD-10-CM/CPT/HCPCS codes, validate documentation, and support revenue cycle. Many openings also include clinical NLP data labeling and model QA tasks.

  • Q: How do these jobs connect to AI/ML workflows?

    Your coding decisions power LLM training pipelines via supervised signals and RLHF. You may annotate notes for named entity recognition, run QA evaluation, perform prompt evaluation, and review large language model evaluation results.

  • Q: Which credentials are preferred?

    Commonly CPC, CCS, RHIT, COC, or specialty certificates. Equivalent experience in facility/professional coding, HCC risk, or audit is also valued.

  • Q: What contract types are available?

    Remote roles include contract, freelance, and full-time. Some projects are part-time sprints for annotation vendors; others are long-term with AI labs or BPOs.

  • Q: What domains might I work in?

    NLP for clinical notes, computer vision for scanned forms, content safety for PHI de-identification, and LLM training for coder-assist tools.

  • Q: What tools are commonly used?

    EHRs and encoders, payer portals, clearinghouses, and annotation platforms. You may evaluate LLM outputs and follow documented annotation guidelines.

  • Q: What’s the difference between entry-level and senior roles?

    Entry-level focuses on production coding and structured labeling. Senior roles add audit leadership, guideline authoring, complex denials, and model QA oversight.

  • Q: How is RLHF applied here?

    Experts review model suggestions, provide corrections and rationales, and score outputs. This feedback improves model behavior via reinforcement learning from human feedback.

  • Q: What compensation can I expect?

    Rates vary by specialty, complexity, and engagement type. Contract and freelance projects pay per task or hour; full-time roles include salaries and benefits.

  • Q: Are international applicants accepted?

    Yes, many remote projects are global. Some roles require local payer knowledge or time zone overlap; all require HIPAA-aligned handling of sensitive data.

  • Q: What compliance standards apply?

    HIPAA, payer policies, audit guidelines, and internal annotation standards. Accuracy and data security are mandatory across coding and labeling work.

  • Q: How do I start?

    Sign up on Rex.zone, complete your profile, upload certifications, and apply to matching remote billing and coding jobs. You’ll receive updates on screenings and assignments.
