M43.06 Spondylolysis, lumbar region

ICD10CM code

#### Name of the Condition
- Spondylolysis, lumbar region

#### Summary
- Spondylolysis in the lumbar region is a condition characterized by a defect or stress fracture in one of the vertebrae of the lower back. This condition can lead to vertebral slippage if part of the bone weakens. It is often asymptomatic but can sometimes cause back pain.

#### Causes
- The exact cause can vary, but it often results from repetitive stress on the lower spine, potentially due to certain sports or physical activities that put excessive pressure on the lumbar spine.

#### Risk Factors
- Participation in sports requiring repeated extension and flexion of the back, such as gymnastics or football.
- Genetic predisposition and a family history of lumbar spine disorders.
- Rapid growth during adolescence may also be a contributing factor.

#### Symptoms
- Persistent lower back pain, which may worsen with activity.
- Stiffness or a feeling of tightness in the lower back.
- Pain may radiate into the buttocks or thighs in some cases.

#### Diagnosis
- Physical examination focusing on the lumbar spine.
- Imaging tests such as X-rays, MRI, or CT scans to confirm the presence of a stress fracture.

#### Treatment Options
- Rest and avoidance of activities that exacerbate symptoms to allow natural healing.
- Physical therapy to strengthen the back and core muscles.
- Pain management with nonsteroidal anti-inflammatory drugs (NSAIDs).
- In severe cases, surgical intervention may be necessary to stabilize the spine.

#### Prognosis and Follow-Up
- With appropriate treatment, most individuals experience significant improvement in symptoms.
- Regular follow-up is recommended to monitor healing and prevent recurrence.

#### Complications
- If untreated, it may progress to spondylolisthesis, where the affected vertebra slips out of place.
- Chronic pain and reduced mobility may occur in severe cases.

#### Lifestyle & Prevention
- Engaging in stretching and strengthening exercises for the back and core muscles.
- Using proper techniques and protective gear in sports to reduce risk.
- Avoiding excessive loading and repetitive stress on the spine.

#### When to Seek Professional Help
- If experiencing persistent or worsening back pain.
- Development of neurological symptoms such as numbness or weakness in the lower extremities.

#### Tips for Medical Coders
- Ensure accurate coding by confirming the site of the condition is the lumbar region.
- Be aware of documentation specificity to distinguish between spondylolysis and spondylolisthesis.
