ICD-9-CM 430

CMS Source: final ICD-9-CM release (version date October 1, 2014). Retired from U.S. claims after September 30, 2015.

430 is a legacy ICD-9-CM diagnosis code for subarachnoid hemorrhage. It was valid on U.S. claims through September 30, 2015 and cannot be reported for services on or after October 1, 2015, when ICD-10-CM replaced the ICD-9 code set. Under the CMS General Equivalence Mappings, its ICD-10-CM replacement is I60.9 (Nontraumatic subarachnoid hemorrhage, unspecified), flagged as an approximate match.

Information for Patients

Brain Diseases

The brain is the control center of the body. It controls thoughts, memory, speech, and movement. It regulates the function of many organs. When the brain is healthy, it works quickly and automatically. However, when problems occur, the results can be devastating.

Hemorrhagic Stroke

A stroke is a medical emergency. There are two types - ischemic and hemorrhagic. Hemorrhagic stroke is the less common type. It happens when a blood vessel breaks and bleeds into the brain. Within minutes, brain cells begin to die. Causes include a bleeding aneurysm, an arteriovenous malformation (AVM), or an artery wall that breaks open.

Questions About 430

Is 430 (subarachnoid hemorrhage) still a valid code?

No. This code belonged to ICD-9-CM, which the United States retired after September 30, 2015. Claims with dates of service on or after October 1, 2015 must use ICD-10-CM codes, such as its replacement I60.9.

What is the ICD-10 replacement for 430?

The General Equivalence Mappings crosswalk this code to ICD-10-CM I60.9 (Nontraumatic subarachnoid hemorrhage, unspecified). The match is flagged as approximate, so confirm it against the clinical documentation before use.

What did 430 mean?

In the final ICD-9-CM release, this code described subarachnoid hemorrhage. It sat in block 430 Subarachnoid hemorrhage under Diseases of the circulatory system (390–459).
