Diagnosis Snapshot

Key Facts
  • Definition : Prior diagnosis of uterine cancer, including endometrial, sarcoma, or other uterine malignancies.
  • Clinical Signs : May be asymptomatic. Abnormal vaginal bleeding, pelvic pain, or mass are possible.
  • Common Settings : Gynecologic oncology clinics, primary care offices, survivorship programs.

Documentation Best Practices

Documentation Checklist
  • Uterine cancer diagnosis date, type, stage
  • Confirmation method: Pathology report, imaging
  • Symptoms: Abnormal bleeding, pelvic pain
  • Prior treatments: Surgery, chemo, radiation
  • Family history of uterine or related cancers

Coding and Audit Risks

Common Risks
  • Unspecified Laterality

    Coding for uterine cancer requires specifying laterality (right, left, bilateral) if applicable. Unspecified laterality can lead to claims rejection or inaccurate data.

  • History vs. Active Cancer

    Accurately differentiating between a history of uterine cancer and currently active disease is crucial for proper coding, staging, and treatment planning.

  • Missing Histology Code

    History of uterine cancer diagnoses must include the specific histology/morphology when documented. Missing codes impact data quality and reimbursement.

Mitigation Tips

Best Practices
  • Code Z85.4 for personal history of uterine cancer.
  • Document date of original diagnosis and type of cancer.
  • Specify stage, treatment, and response to therapy.
  • Query physician for clarification if documentation is vague.
  • Ensure coding aligns with clinical documentation for compliance.

Clinical Decision Support

Checklist
  • Confirm uterine cancer diagnosis code (e.g., C54.X) matches clinical documentation.
  • Verify date of diagnosis and relevant treatment details are documented.
  • Check for family history of uterine or related cancers and document.
  • Review pathology reports to confirm cancer type and stage if applicable.

Quick Tips

Practical Coding Tips
  • Code Z85.4 for personal history

  • Rule out active cancer (C54.X)
  • Check documentation for recurrence (C54.X)
  • Use C54.X for secondary malignancy
