Code Description

ICD-10 D17.4 is a billable code used to indicate a diagnosis of benign lipomatous neoplasm of intrathoracic organs.

Key Diagnostic Point:

Benign lipomatous neoplasms of intrathoracic organs are non-cancerous tumors composed primarily of adipose (fat) tissue that occur within the thoracic cavity. These neoplasms can arise from various intrathoracic structures, including the lungs, mediastinum, and pleura. Clinically, they may present asymptomatically or with symptoms depending on their size and location, such as cough, chest pain, or respiratory distress. Diagnosis typically involves imaging studies like CT scans or MRIs, which can help differentiate these benign tumors from malignant lesions. While benign, these neoplasms require monitoring due to the potential for growth and the possibility of compressing adjacent structures, leading to complications. Surgical intervention may be indicated if the neoplasm causes significant symptoms or if there is uncertainty regarding its nature. Regular follow-up imaging may be necessary to assess for changes in size or characteristics over time.

Frequently Asked Questions

What are the common symptoms of a benign lipomatous neoplasm?

Common symptoms may include cough, chest pain, or respiratory distress, depending on the size and location of the neoplasm.

How is a benign lipomatous neoplasm diagnosed?

Diagnosis is typically made through imaging studies such as CT or MRI, and may require histological examination to confirm its benign nature.

Is surgical intervention always necessary for benign lipomatous neoplasms?

Surgical intervention is not always necessary; it is indicated if the neoplasm causes significant symptoms or if there is uncertainty regarding its nature.

What is the follow-up protocol for patients with benign lipomatous neoplasms?

Regular follow-up imaging may be necessary to monitor for changes in size or characteristics of the neoplasm.
