O13.9
ICD-10-CM
Pregnancy Hypertension

Understanding Pregnancy Hypertension: Find information on gestational hypertension, preeclampsia, eclampsia, chronic hypertension in pregnancy, and blood pressure management during pregnancy. This resource covers clinical documentation, medical coding (ICD-10 codes O10, O11, O13, O14, O15, O16), diagnostic criteria, and treatment guidelines for healthcare professionals. Learn about pregnancy-induced hypertension, severe preeclampsia symptoms, and postpartum preeclampsia management for optimal patient care.

Documentation Best Practices

Documentation Checklist
  • Pregnancy hypertension diagnosis code
  • Document BP readings 140/90 mmHg or higher
  • Onset after 20 weeks gestation, no proteinuria
  • Exclude chronic hypertension, preeclampsia
  • Postpartum BP return to normal within 12 weeks

Coding and Audit Risks

Common Risks
  • Unspecified Hypertension

    Coding hypertension without specifying pre-existing, gestational, or pre-eclampsia risks incorrect reimbursement and quality metrics.

  • Superimposed Pre-eclampsia

    Failing to distinguish pre-eclampsia superimposed on chronic hypertension leads to underreporting severity and impacts patient safety.

  • Gestational Transient HTN

    Miscoding transient gestational hypertension as chronic hypertension can affect long-term patient care and research data accuracy.

Mitigation Tips

Best Practices
  • Accurate ICD-10 coding (O10-O16) for pre-eclampsia, eclampsia, & gestational hypertension is crucial for proper reimbursement.
  • Detailed clinical documentation improves risk adjustment & quality reporting. Specify onset, severity, & treatment.
  • Monitor BP regularly per ACOG guidelines. Consistent documentation supports diagnosis & justifies interventions.
  • Timely review of medical records by CDI specialists ensures accurate & complete coding for optimal compliance.
  • Educate clinicians on hypertension diagnosis nuances for improved documentation and coding accuracy.

Clinical Decision Support

Checklist
  • Verify elevated BP: >140 systolic or >90 diastolic
  • Confirm gestational age: >20 weeks
  • Rule out chronic hypertension: pre-existing or <20 weeks
  • Assess for proteinuria: via urine dipstick or 24-hour urine

Reimbursement and Quality Metrics

Documentation Templates

Patient presents with pregnancy-induced hypertension (PIH), also known as gestational hypertension.  Onset of elevated blood pressure (BP) documented after 20 weeks gestation, with readings consistently at or above 140 systolic andor 90 diastolic.  No proteinuria or other signs or symptoms of preeclampsia currently noted.  Patient denies headaches, visual disturbances, or right upper quadrant pain.  Prior to 20 weeks, blood pressure was consistently within normal limits.  Family history includes hypertension in mother and maternal grandmother.  Medical history is significant for seasonal allergies, managed with over-the-counter antihistamines.  Current medications include prenatal vitamins.  Physical examination reveals normal fetal heart tones and fundal height appropriate for gestational age.  Differential diagnoses considered include chronic hypertension, preeclampsia, and gestational transient hypertension.  Plan includes close monitoring of blood pressure, both at home and during prenatal visits.  Patient educated on symptoms of preeclampsia and instructed to report any changes immediately.  Repeat blood pressure measurements scheduled in one week.  Laboratory testing ordered: complete blood count (CBC), comprehensive metabolic panel (CMP), and 24-hour urine protein.  ICD-10 code O13.9, Pregnancy-induced hypertension, unspecified, assigned.  Monitoring for progression to preeclampsia or eclampsia is crucial for appropriate management and billing and coding.  Treatment plan will be adjusted based on laboratory results and ongoing blood pressure readings.  Patient counseled on the importance of lifestyle modifications, including sodium restriction and increased rest.  Follow-up appointment scheduled in one week to review lab results and reassess blood pressure.
