Z89.511 Acquired absence of right leg below knee

ICD10CM code

#### Name of the Condition
- Acquired absence of right leg below knee
- Sometimes referred to as right below-knee amputation (BKA)

#### Summary
- This condition refers to the loss of the right leg below the knee, typically due to medical intervention such as surgery following severe injury or disease. It is categorized under ICD code Z89.511.

#### Causes
- The condition often results from surgery required due to complications like severe trauma, peripheral vascular disease, diabetes-related complications, or infections that severely damage the limb.

#### Risk Factors
- Conditions such as diabetes, smoking, hypertension, high cholesterol, or chronic infections can increase the likelihood of requiring a below-knee amputation.

#### Symptoms
- The most apparent symptom is the absence of the lower portion of the right leg.
- Potential for phantom limb sensations or pain in the area where the leg was removed.

#### Diagnosis
- Diagnosis typically follows the surgical procedure, as the absence of the limb is apparent.
- Pre-surgery evaluations might include imaging tests (e.g., X-rays, MRIs) and vascular studies.

#### Treatment Options
- Fitting and training for a prosthetic limb are common post-amputation.
- Physical therapy helps individuals adapt to using a prosthesis and regain mobility.
- Pain management may involve medications or therapy for phantom limb pain.

#### Prognosis and Follow-Up
- Many individuals regain significant functionality with a prosthesis.
- Ongoing rehabilitation and periodic follow-up are necessary to address any new issues and ensure the prosthesis fits well and functions optimally.

#### Complications
- Potential complications can include phantom limb pain, infection at the surgical site, and challenges with prosthesis fitting.
- Post-operative complications like deep vein thrombosis (DVT) may occur.

#### Lifestyle & Prevention
- Healthy lifestyle choices can help prevent conditions leading to amputation, such as proper foot care, especially for diabetics, and managing cardiovascular risk factors.
- Regular exercise, a balanced diet, and not smoking are beneficial for overall health.

#### When to Seek Professional Help
- Persistent or severe pain, signs of infection (redness, swelling, fever), or issues with prosthetic limb fitting require medical attention.
- New discomfort or difficulty with mobility should prompt a visit to a healthcare provider.

#### Additional Resources
- Amputee Coalition (www.amputee-coalition.org) for support and information.
- National Limb Loss Resource Center offers educational materials and support.

#### Tips for Medical Coders
- Ensure that both the laterality (right side) and level of amputation (below-knee) are accurately coded.
- Familiarize yourself with related codes for complications or associated conditions.
