Official Coding Guidelines

Nonspecific Z Codes—limit inpatient/outpatient use

14) Nonspecific Z Codes Certain Z codes are so non-specific, or potentially redundant with other codes in the classification, that there can be little justification for their use in the inpatient setting. Their use in the outpatient setting should be limited to those instances when there is no further documentation to permit more precise coding. Otherwise, any sign or symptom or any other reason for visit that is captured in another code should be used. Nonspecific Z codes/categories: Z02.9 Encounter for administrative examinations, unspecified Z04.9 Encounter for examination and observation for unspecified reason Z13.9 Encounter for screening, unspecified Z41.9 Encounter for procedure for purposes other than remedying health state, unspecified Z52.9 Donor of unspecified organ or tissue Z86.59 Personal history of other mental and behavioral disorders Z88.9 Allergy status to unspecified drugs, medicaments and biological substances status Z92.0 Personal history of contraception
