ICD-9-CM 436

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

436 is a legacy ICD-9-CM diagnosis code for acute, but ill-defined, cerebrovascular disease. 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 I67.89 (Other cerebrovascular disease), flagged as an approximate match.

Information for Patients

Stroke

A stroke happens when there is a loss of blood flow to part of the brain. Your brain cells cannot get the oxygen and nutrients they need from blood, and they start to die within a few minutes. This can cause lasting brain damage, long-term disability, or even death.

Questions About 436

Is 436 (acute, but ill-defined, cerebrovascular disease) 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 I67.89.

What is the ICD-10 replacement for 436?

The General Equivalence Mappings crosswalk this code to ICD-10-CM I67.89 (Other cerebrovascular disease). The match is flagged as approximate, so confirm it against the clinical documentation before use.

What did 436 mean?

In the final ICD-9-CM release, this code described acute, but ill-defined, cerebrovascular disease. It sat in block 436 Acute but ill-defined cerebrovascular disease under Diseases of the circulatory system (390–459).
