Find clear guidance on hypertension in pregnancy diagnosis, including gestational hypertension, preeclampsia, and eclampsia. This resource covers clinical documentation requirements, ICD-10 codes (O10, O11, O13-O16), medical coding best practices, and healthcare provider guidelines for accurate diagnosis and management of hypertensive disorders in pregnancy. Learn about blood pressure monitoring, severe hypertension in pregnancy, and postpartum hypertension management.

| Gestational Hypertension |
| Preeclampsia |
| Chronic Hypertension, complicating pregnancy |
Coding O10.9 (Unspecified Hypertension complicating pregnancy) when a more specific code like O13 or O14 is applicable, leading to inaccurate severity reflection and reimbursement.
Misclassifying chronic hypertension (I10) as gestational hypertension (O13), impacting risk adjustment and continuity of care post-partum.
Failing to code superimposed preeclampsia (O14.0x) when it develops in a patient with chronic hypertension, underrepresenting severity and resource utilization.
Patient presents with hypertension in pregnancy. Onset of elevated blood pressure documented at (gestational age). Blood pressure readings consistently above 14090 mmHg on two or more occasions, at least four hours apart. Diagnosis of gestational hypertension, preeclampsia, or chronic hypertension complicating pregnancy considered. Patient denies symptoms of severe preeclampsia such as headache, visual disturbances, or epigastric pain. Laboratory results including complete blood count, comprehensive metabolic panel, liver function tests, and urinalysis ordered to assess for end-organ damage and rule out preeclampsia. Fetal well-being monitored via (specify method, e.g., non-stress test, biophysical profile). Patient education provided regarding blood pressure management, symptoms to monitor, and importance of regular prenatal care. Plan includes close monitoring of blood pressure, laboratory values, and fetal status. Treatment options such as antihypertensive medication discussed and prescribed if indicated. Risks and benefits of treatment explained. Follow-up scheduled in (duration) to reassess blood pressure control and fetal well-being. Differential diagnoses include transient hypertension of pregnancy and white coat hypertension. ICD-10 code (specify code, e.g., O13, O14, O10) assigned based on diagnostic criteria met. Patient advised to contact the clinic immediately if experiencing worsening symptoms or signs of preeclampsia.
