The solution

Write letters that insurers can understand and approve

Twofold helps you generate letters of medical necessity that connect diagnosis, symptoms, function, and proposed treatment so reviewers see exactly why care is required.

  • Clear Statement Of Diagnosis And Symptoms

    Pull key diagnoses, severity, and relevant history into the opening of each letter so payers quickly see what the request is about.

  • Functional Impact And Risk Description

    Describe how the condition affects work, school, self care, relationships, or safety using language that matches payer criteria.

  • Summary Of Prior Treatment Attempts

    Document what has already been tried, how the patient responded, and why additional or different care is needed.

  • Requested Service And Rationale

    State clearly what you are requesting, how it aligns with guidelines, and why it is medically necessary for this specific patient.

  • Support For Duration And Frequency

    Justify how often and how long services, medications, or equipment are needed, tied directly to clinical goals.

  • Payer Friendly Structure

    Use headings and organized paragraphs that make chart reviewers and utilization management teams more likely to read and approve.

  • HIPAA Compliant Letter Generator

    All PHI is encrypted in transit and at rest, handled under a signed BAA so you can safely generate letters that include clinical detail.

  • Copy Ready For Portals And Faxes
