Perinatal period definition (P00-P96)

— ICD-10-CM Official Guidelines for Coding and Reporting, FY2026, Section I.C.16
Use of Z05 codes (newborn suspected condition ruled out)

1) Use of Z05 codes Assign a code from category Z05, Observation and evaluation of newborn for suspected diseases and conditions ruled out, to identify those instances when a healthy newborn is evaluated for a suspected condition/disease that is determined after study not to be present. Do not use a code from category Z05 when the patient is documented to have signs or symptoms of a suspected problem; in such cases code the sign or symptom.
