"This chapter will discuss CPT®, ICD-10-CM, and HCPCS Level II coding for the respiratory, hemic and lymphatic systems, and the mediastinum and diaphragm. Codes found in the respiratory portion of CPT® codes (30000– 32999) describe procedures of the nose, accessory sinuses, larynx (voice box), trachea, bronchi, and the lungs and pleura. The mediastinum is the central cavity of the chest. CPT® 39000–39499 describe procedures of the cavity itself, not of the organs (such as the heart) contained within it.The thoracic diaphragm (CPT® 39501–39599) divides the thoracic cavity from the abdomen, and enables respiration and speech. The hemic and lymphatic systems (CPT® 38100–38999) include the spleen and bone marrow, and the lymph nodes and lymphatic channels (p. 277)."
