Total hip arthroplasty, commonly known as total hip replacement, is a surgical procedure to replace a damaged hip joint with an artificial joint. Accurate diagnosis coding is crucial for medical billing, record-keeping, and data analysis. In the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM), the diagnosis code Z96.643 plays a significant role in identifying patients who have undergone bilateral total hip arthroplasty.
Decoding ICD-10-CM Code Z96.643: Presence of Bilateral Artificial Hip Joints
ICD-10-CM code Z96.643 is specifically designated to indicate the presence of artificial hip joints, bilaterally. This code is used when a patient has received hip replacements in both hips. It falls under the broader category of “Presence of other functional implants,” specifying artificial joints and further pinpointing hip joints on both sides of the body.
Key features of Z96.643:
- Billable and Specific Code: Z96.643 is a billable code, meaning it is recognized for reimbursement purposes by insurance providers. It is also a specific code, providing a detailed level of information about the patient’s condition.
- Effective Date: The 2025 edition of ICD-10-CM, which includes Z96.643, became effective on October 1, 2024. This code has been consistently used in ICD-10-CM since 2016, with no changes through the 2025 update.
- American Standard: Z96.643 is the American ICD-10-CM version. It’s important to note that international versions of ICD-10 may have variations.
Synonyms and Related Terms for Z96.643
To ensure accurate coding and searching, it’s helpful to understand the various synonyms and terms associated with Z96.643. These include:
- History of bilateral total hip arthroplasty (THA)
