Z90.02 Acquired absence of larynx

ICD10CM code

#### Name of the Condition
- Acquired absence of larynx

#### Summary
The acquired absence of the larynx is a condition where the larynx, also known as the voice box, is missing due to surgical removal or traumatic injury. This condition may result in changes to speech and breathing functions.

#### Causes
- The primary cause is a surgical procedure known as laryngectomy, often performed to treat laryngeal cancer or other serious conditions affecting the larynx.
- Severe trauma to the neck area can also lead to the removal of the larynx.

#### Risk Factors
- Having laryngeal cancer or other cancers of the throat that necessitate larynx removal.
- Previous radiation therapy or chemotherapy for head and neck cancers.
- Severe traumatic injuries to the head and neck region.

#### Symptoms
- Loss of natural voice
- Breathing difficulties through the nasal airways
- Difficulty swallowing

#### Diagnosis
- Examination of medical history and current symptoms.
- Imaging tests prior to larynx removal surgery to assess the extent of disease.
- Post-operative physical examination to check surgical outcomes and recovery.

#### Treatment Options
- Speech therapy to learn alternative communication methods, such as esophageal speech or using an electrolarynx.
- Stoma care and management for breathing through a tracheostoma.
- Psychological support and counseling to adjust to lifestyle changes.

#### Prognosis and Follow-Up
- Prognosis largely depends on the underlying reason for the larynx removal.
- Regular follow-up appointments to monitor recovery and check stoma or surgical site.
- Continuous speech therapy may be necessary to maximize communication abilities.

#### Complications
- Potential complications include stoma infections, respiratory difficulties, and challenges with swallowing.
- Emotional or psychological impact due to changes in voice and appearance.

#### Lifestyle & Prevention
- Use of medical alert identification indicating the presence of a stoma.
- Avoidance of smoking and alcohol to reduce the risk of head and neck cancers.

#### When to Seek Professional Help
- Sudden changes in breathing or difficult breathing through the stoma.
- Signs of infection such as redness, swelling, or discharge from the stoma.
- Difficulties in managing day-to-day activities or stress from lifestyle changes.

#### Tips for Medical Coders
- Ensure the code Z90.02 is used specifically for cases involving acquired absence of the larynx.
- Verify and differentiate from congenital absence of the larynx to avoid coding errors.
- Check for additional codes if the condition resulted from cancer treatment or trauma.
