    ICD-10-CM Code For Complications Of Other Internal Prosthetic Devices Implants And Grafts: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group T85 includes complications of other internal prosthetic devices, implants, and grafts such as mechanical malfunction, infection, erosion, migration, and obstruction related to implanted devices. These ICD-10-CM diagnosis codes are used to document device-related complications that capture the nature of the device problem, affected anatomical site, and any associated clinical severity or infection. Accurate coding within the ICD-10-CM T85 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM T85: Complications Of Other Internal Prosthetic Devices, Implants And Grafts Overview

    This group covers complications related to internal prosthetic devices, implants, and grafts used in various body systems, including mechanical failure, infection, migration, erosion, and other device-related issues. These conditions affect multiple organ systems depending on the device location and can cause local and systemic clinical consequences. Accurate coding ensures complete clinical documentation and supports appropriate reimbursement for care related to device complications.

    When to Use

    Use a code from this group when a patient has a documented complication directly related to an internal prosthetic device, implant, or graft and the complication is the focus of care. Select codes that reflect the specific device-related problem and the anatomic site or presence of infection when documented.

    Typical Clinical Scenarios

    • An elderly patient with a long-standing left knee total joint prosthesis presents to the emergency department with acute onset of fever, increasing joint pain, progressive swelling, and purulent drainage from a surgical scar. Imaging and joint aspiration confirm periprosthetic joint infection requiring urgent irrigation and debridement with retention of the implant. A code from this group is assigned to indicate infection of an internal prosthetic joint device. Typical codes: T85.11D, T85.119A.
    • A middle-aged woman with a history of breast reconstruction using an implanted silicone prosthesis reports chronic, progressive breast pain and palpable firmness two years after reconstruction; evaluation reveals capsular contracture with implant malposition causing cosmetic deformity and discomfort. She is scheduled for elective capsulectomy and implant replacement; a code from this group is used to document the mechanical complication of the internal prosthetic device. Typical codes: T85.41XA, T85.418A.
    • A younger patient with a ventricular assist device (VAD) presents to the outpatient clinic for routine follow-up and is found to have persistent minor device leakage and device malfunction without systemic infection, causing decreased device function and need for device revision. The complication is chronic and managed electively, so a code from this group is assigned to capture the structural malfunction of an internal cardiac prosthetic device. Typical codes: T85.21XD, T85.29XA.
