ICD-10-CM Code For Unspecified Maternal Hypertension: Group Overview
The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group O16 includes unspecified hypertensive disorders of pregnancy, childbirth, and the puerperium, covering elevated blood pressure states in pregnant or postpartum patients when a more specific diagnosis is not documented. These ICD-10-CM diagnosis codes are used to document clinical scenarios where hypertension is present but lacks sufficient detail to classify as gestational hypertension with or without proteinuria, preeclampsia, or chronic hypertension complicating pregnancy, capturing disease timing and clinical complexity relevant to maternal care. Accurate coding within the ICD-10-CM O16 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM O16: Unspecified Maternal Hypertension Overview
The ICD-10-CM O16 group represents unspecified hypertensive disorders occurring during pregnancy, childbirth, and the puerperium, targeting maternal cardiovascular and pregnancy-related conditions. These codes capture elevated blood pressure in pregnancy when insufficient detail is available to assign a more specific hypertensive disorder code. Accurate coding matters for appropriate reimbursement and for clear clinical and administrative records that support continuity of care.
