Hematogenous Prosthetic Knee Joint Infection
A patient, who is status post left total knee arthroplasty surgery, and recent wisdom tooth extraction, is diagnosed with hematogenous left knee prosthetic joint infection. He underwent revision of the arthroplasty with exchange of modular components and synovectomy. Does the term “hematogenous” mean the prosthetic joint infection is due to the presence of the prosthesis, or instead is seeded from concurrent infection elsewhere in the body? Is it appropriate to assign code T84.54XA, Infection and inflammatory reaction due to internal left knee prosthesis, initial encounter, for the hematogenous left prosthetic knee joint infection due to the dental infection? ...

Article Overview
This article explains a coding question involving a prosthetic knee joint infection after prior arthroplasty and a recent dental procedure. It addresses how the clinical term and the infection source affect ICD-10-CM assignment, and it is relevant to inpatient, outpatient, and coding professionals working with orthopedic and infectious disease documentation.
Why This Topic Matters
Misclassifying the source of a prosthetic joint infection can lead to incorrect diagnosis coding and downstream claims or record-accuracy issues. The article helps coders and auditors interpret documentation that distinguishes a device-related infection from an infection originating elsewhere.
What You Will Learn
- How hematogenous infection is discussed in relation to prosthetic joint documentation
