Step-by-step explanation:
The CPT manual provides two different codes for the excision of a mediastinal cyst and a mediastinal tumor. For the excision of a mediastinal cyst, the CPT manual provides the code 38930. This code specifically refers to the removal of a mediastinal cyst, which is a fluid-filled sac that can develop within the mediastinum. For the excision of a mediastinal tumor, the CPT manual provides the code 38520. This code is used for the removal of a tumor located within the mediastinum. It is important to use the appropriate code based on the specific procedure being performed.
