Z93.5 is the ICD-10-CM diagnosis code for cystostomy status. It belongs to category Z93 (artificial opening status), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services).

To report this condition, pick the subcode that matches the documentation: Z93.50 (status), Z93.51 (status), Z93.52 (status) and Z93.59 (status).
