What is a medical biller?

Medical billers are professionals responsible for processing and submitting insurance claims for healthcare providers. They ensure that patient information, treatments, and procedures are accurately recorded and billed to insurance companies or patients. Medical billers also follow up on unpaid claims, resolve billing issues, and help healthcare facilities receive proper reimbursement for their services. Their work is crucial for the financial health of medical practices and for ensuring patients are billed correctly.

What does a medical biller do?

Medical billers process services provided to patients and submit claims to insurance companies. They follow up with the claim to ensure it is processed and paid in a timely manner. Any part of the services that are not covered by insurance is then billed to the patient. For certain medical procedures, medical billers also file insurance paperwork for pre-authorization to confirm insurance coverage for the procedure. Medical practices and healthcare facilities rely on medical billers to follow claims and reimbursements to bring in a steady stream of revenue.

What skills and qualifications are needed to be a medical biller?

To thrive as a Medical Biller, you need a solid understanding of medical terminology, insurance processes, and billing procedures, often supported by a certificate or relevant associate degree. Familiarity with medical billing software (such as Kareo or AdvancedMD) and knowledge of coding systems like ICD-10 and CPT are typically required. Attention to detail, organizational skills, and the ability to communicate effectively with patients and insurers are vital soft skills. These competencies ensure accurate claims processing, timely reimbursements, and compliance with healthcare regulations.

What challenges do medical billers face when working with insurance companies?

Medical billers often encounter challenges such as denied or rejected claims, discrepancies in patient information, and frequent changes in insurance policies or coding requirements. Navigating these issues requires strong attention to detail, persistence in following up with insurance representatives, and staying updated on industry changes. Effective communication and problem-solving skills are essential for resolving disputes and ensuring timely reimbursement.

Job description

Role Title: Medical Writer / Clinical Document Author


Role Type: Contractor


Location: Remote


micro1 is engaging Medical Writers / Clinical Document Authors to participate in a customer’s project focused on developing advanced AI-assisted writing tools for clinical documentation. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.


Scope of Work

  1. Author and review realistic evaluation tasks based on Clinical Study Reports, DSURs, PSURs/PBRERs, and related clinical documents to inform AI tool development.
  2. Apply expert judgment to assess whether AI-generated content fulfills clinical template and structural requirements, including ICH E3 organization, section sequencing, cross-referencing, and appendix management.
  3. Evaluate scientific accuracy in narrative sections such as efficacy, safety summaries, discussion, and conclusions, distinguishing true scientific or interpretive errors from stylistic differences.
  4. Trace narrative claims to source records—tables, figures, listings, and protocols—to verify that all assertions are appropriately supported.
  5. Provide clear and structured written rationales for each assessment, enabling precise diagnosis and improvement of AI model behavior.
  6. Collaborate with project leads to refine evaluation frameworks and document best practices for clinical regulatory writing in the context of AI.


Preferred Qualifications

  1. Minimum 5 years of regulatory medical writing experience at a sponsor, CRO, or as an independent consultant.
  2. Direct experience independently authoring or leading the authoring of full Clinical Study Reports, beyond summaries or partial contributions.
  3. Fluency with ICH E3 and conventions for periodic safety documentation (ICH E2F, ICH E2C) and eCTD placement.
  4. Demonstrated ability to read and interpret TFLs and protocol documents, identifying where narrative diverges from source data.
  5. Exceptional written and verbal communication skills, especially in providing structured, actionable feedback on clinical content.
  6. Advanced degree in life sciences, pharmacy, or medicine (PhD, PharmD, MD, MSc), or equivalent depth of authoring experience.
  7. Experience across multiple clinical phases and therapeutic areas; oncology and haematology expertise is especially valued.


Join our customer's team and leverage your authoring expertise to help design the next generation of AI-assisted clinical documentation solutions. This high-bar role offers you the chance to shape how tomorrow's writing teams draft and review regulatory documents — through your expert input, judgment, and real-world experience.
