Work-From-Home Medical Billing and Coding Jobs (Remote)

Work-from-home medical billing and coding jobs at Rex.zone are remote healthcare revenue cycle roles that translate clinical documentation into ICD-10, CPT, and HCPCS codes, perform charge entry, submit claims, and manage denials. These roles also intersect with AI/ML training workflows: human-in-the-loop data labeling of medical notes, QA evaluation of auto-coding outputs, and prompt evaluation for LLM-assisted coding—feeding RLHF-style feedback that improves NLP and computer vision models used in EHR abstraction and OCR. Candidates collaborate with AI labs, tech startups, BPOs, and annotation vendors while ensuring HIPAA compliance and payer guideline adherence.

About the Role

As a remote medical billing and coding professional, you will review EHR documentation, abstract diagnoses and procedures, assign ICD-10-CM/PCS, CPT, and HCPCS codes, complete charge entry, submit claims via clearinghouses, and manage payment posting, denials, and appeals. You will ensure payer guideline compliance (CMS, AMA), maintain audit readiness, and collaborate across revenue cycle teams. Many projects include AI-enabled auto-coding and OCR pipelines where your domain expertise provides human-in-the-loop validation and training data quality improvements.

Key Responsibilities

ICD-10/CPT/HCPCS coding accuracy; charge entry and claim submission; insurance verification and benefits coordination; denial management and root-cause analysis; EOB reconciliation and payment posting; audit preparation and coding guideline updates; EHR documentation QA and query management; data labeling for healthcare NLP and computer vision; QA evaluation of model outputs; prompt evaluation and feedback for LLM-assisted coding; annotation guidelines compliance and model performance improvement.

Qualifications & Skills

CPC, CCA, CCS, RHIT, or RHIA preferred; deep knowledge of ICD-10-CM/PCS, CPT, HCPCS, modifiers, NCCI edits, and payer policies; familiarity with UB-04 and CMS-1500; experience with denials (CO/PR codes) and appeal letters; proficiency in EHR systems (Epic, Cerner, Athena), clearinghouses (Availity, Change Healthcare); HIPAA, PHI handling, and security best practices; Excel/Sheets reporting; strong attention to detail and documentation; plus experience with NLP auto-coding, OCR, annotation tools, and LLM training pipelines is a plus.

Work Arrangements & Modifiers

Remote, WFH roles with contract, freelance, part-time, and full-time options; entry-level pathways with mentorship and senior lead auditor tracks; specialty focus (inpatient, outpatient, pro-fee, anesthesia, radiology, ED); domain intersections with NLP, computer vision, content safety labeling (PHI redaction), and LLM training; employer types include AI labs, tech startups, BPOs, annotation vendors, and established RCM providers.

Tools & Platforms

EHR and practice management systems (Epic, Cerner, eClinicalWorks, Athena); clearinghouses and payer portals; encoder tools (3M, Optum); AI-enabled auto-coding, OCR, and document classification; annotation platforms for data labeling; QA dashboards for model output review; secure VPNs, SSO, and device hardening to maintain HIPAA compliance.

Compensation

Rates vary by specialty, certification, and arrangement: typical ranges are USD $20–35/hr for billing specialists and $25–45/hr for certified coders; per-claim or per-encounter pricing available for freelance contracts; full-time salaries depend on volume, complexity, and geography. Qualified senior auditors and specialty coders may command higher rates.
