Complications of care

Official text from the FY2027 ICD-10-CM Official Guidelines for Coding and Reporting. The wording is quoted exactly.

Guidelines I.B.16; I.C.19.g.4

“Code assignment is based on the provider's documentation of the relationship between the condition and the care or procedure, unless otherwise instructed by the classification.”

“There must be a cause-and-effect relationship between the care provided and the condition, and the documentation must support that the condition is clinically significant.”

“No external cause code indicating the type of procedure is necessary for these codes.”
