M21.932 Unspecified acquired deformity of left forearm

ICD10CM code

#### Name of the Condition
- **Unspecified Acquired Deformity of Left Forearm**
- **ICD Code: M21.932**

#### Summary
- Unspecified acquired deformity of the left forearm refers to a condition where the forearm has developed an abnormal shape or structure due to external factors, rather than congenital issues. This can affect the function and appearance of the forearm.

#### Causes
- The condition can result from various causes such as trauma, fracture misalignment, infection leading to bone or tissue modification, surgical complications, or repetitive strain injuries over time.

#### Risk Factors
- Risk factors include a history of forearm injuries or fractures, frequent participation in activities with high potential for arm injury, and previous surgeries on the arm.

#### Symptoms
- Possible symptoms include visible deformities, restricted range of motion, pain in the forearm, swelling, and functional difficulties in movements like lifting or rotating the arm.

#### Diagnosis
- Diagnosis typically involves physical examination, patient history assessment, X-rays, or other imaging techniques like MRI or CT scans to evaluate the forearm’s structure.

#### Treatment Options
- Treatments may include physical therapy to improve function, braces or splints to support the arm, and surgical intervention to correct severe deformities. Pain relief medications might also be prescribed.

#### Prognosis and Follow-Up
- The prognosis varies depending on severity and cause. Many patients recover full function with proper treatment. Regular follow-up is essential to monitor progress and address any complications early.

#### Complications
- Untreated deformities can lead to chronic pain, permanent loss of motion, and decreased ability to carry out daily tasks.

#### Lifestyle & Prevention
- Engaging in exercises that enhance arm strength and flexibility, using protective gear during high-risk activities, and adhering to post-injury rehabilitation protocols can help prevent the condition.

#### When to Seek Professional Help
- Immediate medical attention is advised if the forearm appears deformed, if there's significant pain following an injury, or if there is a noticeable loss of arm function.

#### Tips for Medical Coders
- Ensure documentation clearly states the condition is acquired and specific to the left forearm.
- Avoid using this code for congenital deformities; review notes for clarification if deformity status is not clear.
