    Coding Audit

    What Are Medical Coding Services?

    Medical coding services convert the diagnoses, procedures and supplies in a patient record into standard alphanumeric codes that payers use to decide what to pay. The codes are the language of every claim, so accuracy decides both speed and amount of payment.

    Three code sets do most of the work. ICD 10 codes describe the diagnosis. CPT codes, maintained by the American Medical Association, describe the procedures and services. HCPCS Level II codes cover supplies, drugs and services such as ambulance transport.

    Modifiers add detail to a code. A missing or wrong modifier is one of the most common causes of denial and underpayment.

    The Code Sets Our Coders Use

    Our medical coding services apply each code set to the right part of the claim.

    How Our Medical Coding Services Work

    Our medical coding services follow a six step review, so each claim carries codes the record supports.

    1. Documentation review

    Coders read the full record to find every billable service and diagnosis.

    2. Code assignment

    ICD 10, CPT and HCPCS codes are assigned from the documentation.

    3. Modifier and bundling check

    We apply modifiers correctly and check bundling edits before submission.

    4. Medical necessity link

    Diagnoses are linked to procedures so the claim supports the service.

    5. Quality audit

    A second review checks a sample of claims for accuracy by provider and payer.

    6. Provider feedback

    Documentation gaps are shared with providers so future visits are coded fully.

    Specialty Coding Experience

    Coding rules differ by specialty. Emergency departments use their own E/M levels, orthopedic practices code surgical procedures and implants, and behavioral health follows parity and time based rules.

    Our coders work across more than 32 specialties, including emergency medicine, urgent care, family practice, internal medicine, cardiology and radiology. See the full list on our specialties page. Accurate codes also feed our claim preparation services and reduce work for denial management.

    Signs Your Coding Needs an Audit

    These patterns often point to coding problems rather than payer problems.
    • Repeated denials for bundling or medical necessity
    • Payments that come in lower than your fee schedule
    • High use of a single E/M level across providers
    • Frequent modifier errors on claims
    • Provider notes that do not support the billed code
    • No coding audit in the last 12 months

    Medical Coding Services FAQs

    Medical coding services convert diagnoses, procedures and supplies in a patient record into standard codes used on insurance claims. Accurate coding helps claims get paid correctly and on time.
    ICD 10 codes describe the patient diagnosis, which is the reason for care. CPT codes describe the procedures and services the provider performed. A claim needs both, and they must support each other.
    ICD 10 updates take effect every October 1 and CPT updates every January 1. HCPCS Level II codes are updated through the year. Our coders train on every change before it takes effect.
    ZanexMed uses certified medical coders. Common credentials include the CPC from AAPC and the CCS from AHIMA.
    A coding audit compares the codes billed with what the documentation supports. It finds undercoding, overcoding and missing modifiers, and it lowers audit risk.
    Coding is usually priced as part of a percentage of collections, typically 3% to 8% for full billing, or per chart for coding only. See our pricing page for details.
