ICD-10-CM Code For Nontraumatic Intracerebral Hemorrhage: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group I61 includes diagnoses for nontraumatic intracerebral hemorrhages specifying location within the brain such as lobar, deep, cerebellar, or brain stem involvement and whether the hemorrhage is specified or unspecified. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving spontaneous bleeding into brain parenchyma, capturing severity, anatomical location, and associated complications relevant to cerebrovascular disease. Accurate coding within the ICD-10-CM I61 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM I61: Nontraumatic Intracerebral Hemorrhage Overview

The ICD-10-CM I61 group represents nontraumatic bleeding into the brain parenchyma, commonly referred to as spontaneous intracerebral hemorrhage. These diagnoses target cerebrovascular injury affecting brain tissue rather than subarachnoid or traumatic hemorrhages. Accurate coding is important for clinical communication and supports appropriate reimbursement and resource allocation.

When to Use

Use a code from this group when a clinician documents a nontraumatic intracerebral hemorrhage confirmed by imaging or clinical evaluation and when the record specifies the anatomical site or laterality. Select the most specific subcode available to reflect location and any documentation of related complications to ensure accurate clinical and administrative records.

Typical Clinical Scenarios

An elderly patient with sudden-onset severe headache, rapid neurologic decline, and unilateral weakness is brought to the emergency department after collapsing at home; CT head without contrast shows a localized spontaneous intracerebral bleed in the basal ganglia without evidence of trauma or aneurysm, prompting acute neurosurgical and critical care management. A code from this group is assigned to capture the nontraumatic intracerebral hemorrhage as the primary acute cerebrovascular event. Typical codes: I61.0, I61.2
A middle-aged patient with poorly controlled hypertension presents to clinic with persistent focal neurologic deficits and an MRI performed weeks after an acute event demonstrates a resolved but clearly identified intracerebral hematoma in the cerebellum that required inpatient treatment; current visits focus on rehabilitation and secondary stroke prevention. A diagnosis from this group is used to document the recent nontraumatic intracerebral hemorrhage as the underlying cause of ongoing deficits and care planning. Typical codes: I61.6, I61.3
A hospitalized patient admitted for atrial fibrillation on anticoagulation develops sudden altered mental status and is found on emergent imaging to have a new lobar intracerebral hemorrhage; anticoagulation is reversed and the bleed is managed as a serious inpatient complication affecting anticoagulation strategy and prognosis. A code from this group is assigned to record the nontraumatic intracerebral hemorrhage as a significant inpatient complication/comorbidity. Typical codes: I61.4, I61.5
