ICD-10-CM Code For Pre Existing Hypertension With Pre Eclampsia: Group Overview
The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group O11 includes diagnoses of chronic (pre-existing) hypertension in pregnancy that is complicated by pre-eclampsia, often manifesting with new or worsening proteinuria, edema, or end-organ dysfunction. These ICD-10-CM diagnosis codes are used to document clinical scenarios where baseline hypertensive disease is present prior to pregnancy and is complicated by the development of pre-eclampsia, capturing disease severity and maternal organ involvement. Accurate coding within the ICD-10-CM O11 group supports proper claim adjudication and complete clinical documentation and appropriate reimbursement.
