What does the CPT code 27447 describe?

The CPT code 27447 specifically describes a total knee arthroplasty, also known as total knee replacement surgery. This surgical procedure involves replacing the damaged or worn parts of the knee joint with artificial components to improve function and relieve pain in patients with severe knee arthritis or other knee joint issues.

In the context of surgical coding, total knee arthroplasty is a well-defined procedure that is categorized under joint replacement surgeries. The details associated with this code include not only the technique involved but also the indication for surgery, which typically entails significant osteoarthritis or degenerative joint disease.

Understanding this code is essential for properly documenting and billing for the procedure, as it encompasses the entire surgical process from preparation through implantation of the prosthetic components. This specificity helps in ensuring appropriate reimbursement and tracking of surgical interventions.

In contrast to other procedures listed, such as arthroscopy for knee repair or treatments for knee fractures, which involve different surgical techniques and purposes, 27447 remains distinctly focused on the complete replacement of the knee joint. Thus, familiarity with this code is crucial for surgical coding professionals.
