About I69.398

I69.398 is the ICD-10-CM diagnosis code for other sequelae of cerebral infarction. It belongs to category I69 (sequelae of cerebrovascular disease), block I60-I69 (cerebrovascular diseases) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within I69.39, choose I69.398 (Other sequelae of cerebral infarction) only when documentation doesn't support a more specific option: apraxia following cerebral infarction (I69.390), dysphagia following cerebral infarction (I69.391), facial weakness following cerebral infarction (I69.392) and ataxia following cerebral infarction (I69.393).

Use an additional code to identify the sequelae.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 056 (Degenerative Nervous System Disorders with MCC, relative weight 2.2655) and DRG 057 (Degenerative Nervous System Disorders without MCC, relative weight 1.2838), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 438.89 (other late effects of cerebrovascular disease).
