These 'Z' codes communicate the status of a transplant. The only documentation needed is the provider's documentation of presence or history of there having been a transplant. These codes belong in HCC 186 Major Organ Transplant or Replacement Status Disclaimer: This guidance is to be used for an easy reference; the ICD-9-CM and ICD-10-CM code books and the Official Guidelines for Coding and Reporting are the authoritative references for accurate and complete
