Brain Diseases

Your brain is the control center of your body. It controls your thoughts, memory, speech, and movement. It regulates the function of many organs. It's part of your nervous system, which also includes your spinal cord and peripheral nerves. The nervous system sends signals between your brain and the rest of the body.

Questions About I69.911Overview

What is the ICD-10 code for memory deficit following unspecified cerebrovascular disease?

The ICD-10-CM code for memory deficit following unspecified cerebrovascular disease is I69.911 (sometimes written as I69911). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is I69.911 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report memory deficit following unspecified cerebrovascular disease on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does I69.911 group to?

When memory deficit following unspecified cerebrovascular disease is the principal diagnosis on an inpatient stay, it groups to MS-DRG 57, 56, with relative weights from 1.2835 to 2.2649 depending on complications. Higher weights mean higher Medicare reimbursement.

Can I69.911 be reported with I69.3?

Not as a rule. The Excludes1 note at I69.9, which applies to I69.911, lists "sequelae of stroke (I69.3)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is the ICD-9 equivalent of I69.911?

Under the General Equivalence Mappings, memory deficit following unspecified cerebrovascular disease converts to ICD-9-CM 438.0 (late ef CV dis-cognf def). The mapping is approximate, so confirm the match fits the documentation.
