Documentation Best Practices

Documentation Checklist
  • Document two or more of: oligo/anovulation, hyperandrogenism, polycystic ovaries.
  • Exclude other androgen excess disorders (e.g., Cushing syndrome, congenital adrenal hyperplasia).
  • Specify Rotterdam criteria met for PCOS diagnosis.
  • Note LH/FSH ratio if obtained and relevant.
  • Document relevant labs: testosterone, DHEA-S, androstenedione, 17-OH progesterone.

Coding and Audit Risks

Common Risks
  • Unspecified PCOS Type

    Coding PCOS without specifying type (e.g., classic, non-classic) when documented leads to inaccurate severity reflection and potential payment errors.

  • Missed Manifestations

    Overlooking associated diagnoses like hirsutism, infertility, or insulin resistance impacts risk adjustment and care planning.

  • Rule-Out vs. History Of

    Incorrectly coding suspected or ruled-out PCOS as a confirmed history can inflate prevalence data and trigger unnecessary audits.

Mitigation Tips

Best Practices
  • Document ALL PCOS diagnostic criteria: labs, imaging, oligomenorrhea.
  • Code E28.2 for PCOS. Use Z87.890 for personal hx of PCOS.
  • Specific ICD-10 codes improve HCC risk adjustment accuracy.
  • Regular chart reviews ensure complete PCOS documentation for compliance.
  • Detailed clinical notes support medical necessity for PCOS treatments.

Clinical Decision Support

Checklist
  • 1. Verify irregular menses documented (ICD-10: N28.8)
  • 2. Confirm hyperandrogenism signs/symptoms (hirsutism, acne)
  • 3. Check polycystic ovaries on ultrasound (ICD-10: PCO2.0)
  • 4. Exclude other androgen excess disorders (Cushing syndrome)

Reimbursement and Quality Metrics

Impact Summary
  • Polycystic Ovary Syndrome reimbursement relies accurate ICD-10 coding (E28.2).
  • PCOS coding errors impact hospital case mix index and financial reporting.
  • Correct PCOS diagnosis coding improves quality metrics for reproductive health.
  • Timely PCOS diagnosis documentation ensures appropriate reimbursement and care management.
