Non-billable headerNot valid on its own. Use one of the more specific codes under it.

I69.91 is a non-billable ICD-10-CM code header for cognitive deficits following unspecified cerebrovascular disease. Report a more specific code from it instead. It is part of the FY2027 code set, effective October 1, 2026. The more specific codes under it are I69.910 Attention and concentration deficit following unspecified cerebrovascular disease, I69.911 Memory deficit following unspecified cerebrovascular disease, I69.912 Visuospatial deficit and spatial neglect following unspecified cerebrovascular disease, I69.913 Psychomotor deficit following unspecified cerebrovascular disease and 4 more. Its coding notes include a Use additional code instruction, 7 Excludes1 entries and 10 Excludes2 entries.

Guidelines tips

From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.

These codes identify whether the dominant or nondominant side is affected. The Guidelines give defaults when the side is documented but dominance is not.

Guidelines I.C.9.d.1; I.C.6.aHemiplegia and monoplegia: dominant and nondominant sideRead the official text

I69 requires neurologic deficits. It can be reported alongside a current I60–I67 code when deficits from an old event are also present.

Notes

Inherited from I69 Sequelae of cerebrovascular disease
  • Category I69 is to be used to indicate conditions in I60-I67 as the cause of sequelae. The 'sequelae' include conditions specified as such or as residuals which may occur at any time after the onset of the causal condition
