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

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group T84 includes complications of internal orthopedic prosthetic devices, implants, and grafts such as mechanical loosening, infection, displacement, and periprosthetic fractures. These ICD-10-CM diagnosis codes are used to document postoperative device-related complications, capturing the nature of device failure, infection status, and associated musculoskeletal involvement. Accurate coding within the ICD-10-CM T84 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM T84: Complications Of Internal Orthopedic Prosthetic Devices, Implants And Grafts Overview

This group represents complications related to internal orthopedic prosthetic devices, implants, and grafts, such as joint prostheses, fixation devices, and bone grafts. It targets musculoskeletal and device-related postoperative conditions that can affect joint function, wound healing, or implant integrity. Accurate coding matters because it documents device-related complications that impact clinical management and supports appropriate reimbursement for surgical and postoperative care.

ICD-10-CM T84: Complications Of Internal Orthopedic Prosthetic Devices, Implants And Grafts Overview

When to Use

Use a code from this group when a patient presents with a documented complication related to an internal orthopedic prosthetic device, implant, or graft, such as loosening, infection, displacement, or fracture around the device. Select the most specific code that describes the nature of the complication and the anatomical location when documented in the medical record.

Typical Clinical Scenarios

An elderly patient with a long-standing total hip arthroplasty presents to the emergency department with acute onset severe groin pain and inability to bear weight after a low-energy fall. Radiographs show periprosthetic fracture with evidence of loosening around the femoral component; the patient requires admission for surgical fixation or revision. A code from this group is assigned to capture the fracture/loosening complication of the internal prosthetic hip device. Typical codes: T84.020A, T84.021A
A middle-aged patient with a history of knee arthroplasty reports gradually worsening knee swelling, erythema, and intermittent drainage over several weeks; aspiration yields purulent fluid and cultures grow Staphylococcus aureus. The patient is evaluated in clinic and started on IV antibiotics with planned debridement and possible prosthesis removal; the encounter is coded to describe infection of the implanted orthopedic device. Typical codes: T84.050A, T84.051A, T84.058A
A young adult seen in outpatient pain management for chronic mechanical knee pain and instability two years after anterior cruciate ligament (ACL) reconstruction with a synthetic graft. Imaging demonstrates graft failure and implant wear without acute infection; the visit documents ongoing device-related mechanical complication as a reason for elective revision surgery scheduling. Typical codes: T84.090A, T84.091A
