About the 3C Body System
The ICD-10-PCS root operation Indwelling Device (character 3C) pertains to the placement of a device that is intended to remain in or on a body part for an extended period. This operation focuses on the installation of such equipment to provide ongoing therapeutic or diagnostic support.
Within the Administration section, the operation specifically involves putting in or on a cleansing substance, as exemplified by the code 3C1, which represents Irrigation. This procedure typically entails introducing a sterile liquid to clean a body part, such as a wound or cavity, with the aid of an indwelling device, ensuring continuous or controlled delivery. Understanding and coding this operation correctly is essential for documenting treatments that combine device placement with administration procedures, emphasizing the method and intent of maintaining hygiene or treatment via sustained irrigation.
