Find information on pregnancy-induced hypertension (PIH), including gestational hypertension, preeclampsia, and eclampsia. Learn about diagnosis codes (ICD-10 O14, O15), clinical documentation requirements, and healthcare management for PIH. This resource covers blood pressure monitoring during pregnancy, severe hypertension in pregnancy, proteinuria, and other key symptoms. Explore guidelines for accurate medical coding and best practices for documenting PIH in patient charts.

Pre-eclampsia developing after 20 weeks of gestation.
Mild to moderate pre-eclampsia
Pre-eclampsia not severe enough to be classified as severe.
Severe pre-eclampsia
Pre-eclampsia with serious complications like high blood pressure.

| High blood pressure during pregnancy. |
| High blood pressure with kidney involvement in pregnancy. |
| Seizures due to pregnancy-induced hypertension. |
Coding PIH without specifying onset (early, late, or unspecified) leads to inaccurate severity reflection and potential DRG misassignment.
Documenting mild hypertension as pre-eclampsia without sufficient supporting evidence can cause inflated case severity and improper reimbursement.
Incorrectly coding chronic hypertension with superimposed PIH instead of distinct codes can lead to inaccurate data reporting and quality metrics.
Patient presents with pregnancy-induced hypertension (PIH), also known as gestational hypertension. Onset of hypertension after 20 weeks of gestation, documented as blood pressure readings consistently greater than or equal to 140/90 mmHg on two occasions at least four hours apart, with no proteinuria or other signs or symptoms of preeclampsia. Patient denies headaches, visual disturbances, or right upper quadrant pain. No edema noted. Fetal heart tones are regular and reactive. Differential diagnosis includes chronic hypertension, preeclampsia, and eclampsia. Plan includes close monitoring of blood pressure, urinalysis for proteinuria at each prenatal visit, and assessment of fetal well-being. Patient education provided on signs and symptoms of preeclampsia, importance of regular prenatal care, dietary recommendations including sodium restriction, and blood pressure management. ICD-10 code O13. Regular follow-up scheduled to monitor for progression to preeclampsia or other hypertensive disorders of pregnancy. Patient advised to contact the office immediately if she experiences headache, vision changes, swelling in the hands or face, or abdominal pain.
