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.

Guidelines I.C.9.d.2; I.C.9.d.3Sequelae of cerebrovascular disease (I69)Read the official text
