CPT® Code 38305

The procedure described by CPT® Code 38305 pertains to the drainage of a lymph node abscess or lymphadenitis that is extensive in nature. This involves a thorough examination of the lymph node, where the physician palpates the area to identify the greatest point of fluctuance, indicating the presence of an abscess. To facilitate the procedure, a local anesthetic is administered to ensure patient comfort. Following this, an incision is made in the skin over the lymph node, and deeper tissues may be dissected as necessary to adequately expose the site of the abscess. The lymph node itself is then incised to allow for drainage of the accumulated pus or fluid. During this process, cultures may be collected and sent to a laboratory for further analysis to identify any organisms present, which can be crucial for determining appropriate treatment. After the drainage is completed, the incision may be managed in several ways: it can be packed open to promote drainage, a drain may be placed to facilitate ongoing fluid removal, or the incision may be closed depending on the specific circumstances of the procedure. It is important to note that CPT® Code 38305 is specifically used for extensive procedures that involve deep tissue dissection, packing or drain placement, and/or secondary closure, distinguishing it from simpler procedures that involve superficial lymph nodes and primary closure, which are coded under CPT® Code 38300.
