Screening Z codes

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

Guidelines I.C.21.c.5

“The testing of a person to rule out or confirm a suspected diagnosis because the patient has some sign or symptom is a diagnostic examination, not a screening.”

“A screening code may be a first-listed code if the reason for the visit is specifically the screening exam.”
