What history of brain aneurysm ICD codes can I use?
When documenting a history of a brain aneurysm, several ICD-10-CM diagnosis codes may apply depending on the patient's clinical status, whether the aneurysm is current, previously treated, ruptured, or related to family history. The most relevant ICD-10 codes include:
Z86.79 – Personal history of other diseases of the circulatory system
Used to indicate a personal history of brain aneurysm or other circulatory system diseases that are no longer active. Common in follow-up care for nonruptured acquired cerebral aneurysm or ruptured cerebral aneurysm previously treated.
Z82.49 – Family history of ischemic heart disease and other diseases of the circulatory system
This code documents a family history of cerebral aneurysms, ischemic heart disease, or other circulatory conditions. It helps assess genetic risk for stroke, aneurysm, or cerebral hemorrhage.
Z86.73 – Personal history of TIA and cerebral infarction without residual deficits
Use this code for patients with a resolved stroke or transient ischemic attack (TIA) with no lasting deficits. It’s important in patients with prior cerebral infarction potentially related to an aneurysm.
I67.1 – Cerebral aneurysm, nonruptured
Used when a nonruptured cerebral aneurysm is currently present in a patient. Its application include cerebral arteriovenous fistula (acquired), internal carotid artery aneurysm, (intracranial portion) detected through imaging.
I60.7 – Nontraumatic subarachnoid hemorrhage from unspecified intracranial artery
This code captures ruptured cerebral aneurysms resulting in subarachnoid hemorrhage without a specified artery. It is commonly linked to hemorrhagic stroke and emergency neurovascular care.
