T84.51XA is a billable diagnosis code used to specify a medical diagnosis of infection and inflammatory reaction due to internal right hip prosthesis, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

T84.51XA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like infection and inflammatory reaction due to internal right hip prosthesis. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Patient Education


Hip Replacement

Hip replacement is surgery for people with severe hip damage. The most common cause of damage is osteoarthritis. Osteoarthritis causes pain, swelling, and reduced motion in your joints. It can interfere with your daily activities. If other treatments such as physical therapy, pain medicines, and exercise haven't helped, hip replacement surgery might be an option for you.

During a hip replacement operation, the surgeon removes damaged cartilage and bone from your hip joint and replaces them with new, man-made parts.

A hip replacement can:

  • Relieve pain
  • Help your hip joint work better
  • Improve walking and other movements

The most common problem after surgery is hip dislocation. Because a man-made hip is smaller than the original joint, the ball can come out of its socket. The surgery can also cause blood clots and infections. With a hip replacement, you might need to avoid certain activities, such as jogging and high-impact sports.
