Aftercare following explantation of knee joint prosthesis
ICD10CM code
Name of the Condition
- Aftercare Following Explantation of Knee Joint Prosthesis (ICD-10 Code: Z47.33)
- Also referred to as post-operative care after knee prosthesis removal or knee implant removal aftercare.
Summary
- This condition refers to the medical care and management that follow the surgical removal of a knee joint prosthetic. The process is essential to ensure proper healing and recovery after explantation surgery, which might be necessary due to infection, mechanical failure, or other complications.
Causes
- The removal of a knee joint prosthesis can be caused by:
- Infections around the prosthetic joint.
- Prosthetic joint loosening or mechanical failure.
- Persistent pain or stiffness.
- Rejection of the implant by the body.
Risk Factors
- Factors increasing the likelihood of requiring explantation include:
- Previous joint infections.
- Severe osteoarthritis or rheumatoid arthritis.
- History of joint replacements and revisions.
- Excess body weight putting stress on the joint.
- Poor general health or compromised immune system.
Symptoms
- Post-explantation symptoms might include:
- Pain or swelling around the operated joint.
- Reduced mobility or stiffness.
- Drainage or redness indicating possible infection.
Diagnosis
- Follow-up care involves:
- Physical examination by a healthcare professional.
- Imaging tests like X-rays or MRIs to assess joint and tissue conditions.
- Blood tests to monitor for infection or inflammation levels.
Treatment Options
- Treatment focuses on:
- Medications including antibiotics if infection is present.
- Physical therapy to restore mobility and strengthen muscles.
- Pain management strategies to ensure comfort during recovery.
- Possible re-implantation of a new prosthesis once the joint is healthy.
Prognosis and Follow-Up
- The prognosis largely depends on the reason for explantation and the patient's general health.
- Regular follow-ups with doctors and specialists are crucial to monitor healing progress, manage any complications, and determine the timing for a potential new implant.
Complications
- Potential complications may include:
- Joint stiffness or reduced mobility.
- Chronic pain.
- Recurrent infections.
- Delays in re-implantation or need for further surgical interventions.
Lifestyle & Prevention
- Patients are encouraged to:
- Engage in recommended physical therapy exercises.
- Maintain a healthy weight to lessen joint stress.
- Follow an infection-prevention protocol.
- Ensure good nutritional support to promote healing.
When to Seek Professional Help
- Immediate medical attention should be sought if:
- Severe pain, swelling, or redness occurs.
- Fever or other signs of systemic infection appear.
- Unexpected changes in joint mobility are experienced.

Tips for Medical Coders
- Confirm the explantation procedure and the aftercare status before assigning Z47.33.
- Ensure documentation clearly indicates that the patient is receiving aftercare for the removal of a knee joint prosthesis.
- Avoid coding errors by distinguishing between procedures related to removal, follow-up after removal, and new prosthetic implantations.
