About the Role

You will code encounters and procedures using ICD-10-CM/PCS, CPT/HCPCS, and E/M rules, submit clean claims, track payments, and resolve denials. Work spans inpatient/outpatient, pro-fee, and specialty lines. Many projects intersect AI/ML workflows, supporting data labeling, NER of diagnoses, HCC risk adjustment mapping, and audit feedback loops for model-assisted coding.

Key Responsibilities

Perform accurate code assignment, DRG grouping, E/M leveling, and modifier usage; prepare and transmit claims; manage payer follow-up; conduct denial root-cause analysis; complete audit/QA cycles; document annotation guidelines compliance; contribute to training data quality for coding assistance tools; provide prompt evaluation and RLHF feedback to improve model performance.

Required Skills

CPC, CCS, CPB, CRC, or equivalent certification; mastery of ICD-10, CPT, HCPCS, NCCI edits, and payer policies; familiarity with HCC/RAF, LCD/NCD, and revenue cycle management; strong audit accuracy, documentation integrity, HIPAA/PHI handling, and EHR proficiency (Epic, Cerner, Athena). Clear communication, time management, and remote collaboration are essential.

Preferred Experience

Inpatient DRG assignment, pro-fee specialty coding (ED, surgery, anesthesia), risk adjustment, charge capture, denial prevention strategies, and QA sampling. Experience with data labeling, named entity recognition, annotation tools, LLM training pipelines, RLHF for coding assistants, and OCR/computer vision annotation of clinical documents is a plus.

Tools & Platforms

Use encoders (3M 360, TruCode), EHRs (Epic, Cerner, Meditech), clearinghouses, payer portals, and audit utilities. AI-related tasks may involve labeling tools (Labelbox, Prodigy), prompt evaluation dashboards, and document OCR pipelines. Work is coordinated through Rex.zone for project access, communication, and QA evaluation.

Employment Types & Modifiers

Openings include remote, contract, freelance, and full-time roles. We have entry-level positions with mentorship and senior roles leading audits, training, and complex specialty coding. Flexible schedules across time zones and weekend/night shifts are available based on client needs.

Domains & Use Cases

Projects span NLP for clinical text, computer vision for document OCR, LLM training for coding assistants, and content safety labeling for PHI detection. Typical tasks include diagnosis/procedure entity mapping, guideline validation, and model performance evaluation to strengthen healthcare AI systems.

Employer Types

Work with AI labs, tech startups, hospitals, physician groups, payers, BPOs, and annotation vendors. Assignments range from production coding and billing to audit/QA, data labeling, and model evaluation engagements hosted via Rex.zone.

Compensation

USD $22–48 per hour depending on certification, modality, and complexity. Contract and freelance may use per-claim or per-chart rates with QA bonuses. Senior audit leads may receive premium rates. Exact pay and benefits vary by employer type and project scope.

Location & Scheduling

Fully remote roles. US-based coders preferred for payer-specific work; international coders may join global labeling and NLP projects if they meet compliance standards. Schedules accommodate US, EU, and APAC time zones with requirements set per client.

Workflow & Quality Metrics

Focus on training data quality, annotation guidelines compliance, audit accuracy, clean claim rate, first-pass payment, denial reduction, and model performance improvement. Participation in large language model evaluation and feedback loops enhances coding assistance reliability.

Career Growth

Advance from entry-level production coding to senior auditor, QA lead, or RCM analyst. Cross-train in NLP/NER labeling, prompt engineering, and AI evaluation to expand into healthcare data operations and LLM training pipelines via Rex.zone.

How to Apply

Create a profile on Rex.zone, upload certifications and sample audit reports, and indicate modalities (inpatient, outpatient, pro-fee). Complete a short skills assessment and, for AI projects, a labeling/NER test. Qualified candidates are matched to remote openings.

Frequently Asked Questions

  • Q: What is the role entity for this page on Rex.zone?

    Remote Medical Coding and Billing Specialist, including certified coders, billers, and RCM analysts who perform ICD-10/CPT/HCPCS code assignment, claims submission, denial management, and audit/QA, with optional participation in healthcare AI labeling and evaluation.

  • Q: Which certifications are required or preferred?

    CPC, CCS, CPB, CRC, or equivalent. Specialty experience in E/M leveling, DRG assignment, and HCC risk adjustment is preferred. Strong knowledge of NCCI edits, payer rules, and HIPAA compliance is essential.

  • Q: How do AI/ML workflows relate to medical coding work?

    Coders help label clinical text for named entity recognition, validate guideline adherence, and provide prompt evaluation and RLHF feedback to coding assistants. These tasks improve training data quality and model performance in LLM-powered RCM tools.

  • Q: What employment types are available?

    We offer remote contract, freelance, and full-time roles across entry-level and senior tiers. Senior auditors lead QA, denial prevention, and training. Availability may include weekends or night shifts depending on the client.

  • Q: What tools will I use?

    Common tools include 3M 360, TruCode, Epic, Cerner, Meditech, payer portals, clearinghouses, and audit utilities. For AI projects, you may use Labelbox or Prodigy for data labeling and dashboards for large language model evaluation.

  • Q: Is international remote work allowed?

    Yes for data labeling and NLP projects that are not payer-specific, provided you meet privacy, security, and HIPAA-like standards. US-based coders are preferred for claims submission and payer-facing RCM tasks.

  • Q: How are candidates evaluated?

    You will complete a coding accuracy test, a denial analysis scenario, and, for AI projects, a short NER labeling and prompt evaluation exercise. We also review certification status and audit metrics.

  • Q: What are typical pay ranges?

    Rates vary by certification, modality, and complexity. Typical ranges are USD $22–48 per hour, with higher rates for senior audit leads or specialized inpatient coding. Contract work may use per-chart or per-claim pricing.

  • Q: What distinguishes entry-level from senior roles?

    Entry-level focuses on production coding and billing with supervision. Senior roles handle complex specialty coding, lead audits, mentor teams, optimize denial prevention, and often contribute to AI workflow design and QA evaluation.

  • Q: How do I apply on Rex.zone?

    Create a Rex.zone profile, upload certifications and experience, select your employment preferences (remote, contract, freelance, full-time), and finish the skills assessments. Our team will match you to suitable openings.
