Z90: Acquired absence of organs, not elsewhere classified
The Z90 category in the ICD-10 WHO 2016 classification refers to a group of conditions characterized by the acquired absence of certain organs, which is not otherwise specified in the medical coding system. These conditions arise from surgical removal of an organ, such as in the case of an appendectomy or loss of an organ or a part of it due to injury or disease. This absence of organs can have numerous impacts on the body's function, dependent primarily on the specific organ absent. Symptoms can range significantly depending on the organ that has been removed, from changes in digestion with appendix or gallbladder removal to potential changes in speech with the loss of vocal cords. Disease progression may appear static, with initial effects from organ loss being mitigated over time through bodily adaption and/or medical intervention, to dynamic, where more severe and increasing symptoms may occur from the loss of certain organs like the kidney or lung.
