Guidelines tips

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

The trimester character comes from the provider's documentation for the current encounter. The unspecified trimester code should rarely be used.

Guidelines I.C.15.a.3; I.C.15.a.5Pregnancy: the trimester characterRead the official text

Code assignment depends on the provider's documentation linking the infection to the procedure. The site infection is sequenced first, with an additional code for sepsis following a procedure and one for the infectious agent.

Guidelines I.C.1.d.5Sepsis due to a postprocedural infectionRead the official text
