Which term describes the swelling of tissues with lymph caused by obstruction or removal of lymphatic vessels?

The correct term for the swelling of tissues with lymph due to obstruction or removal of lymphatic vessels is lymphedema. This condition occurs when there is an accumulation of lymph fluid in the interstitial tissue, leading to swelling, particularly in the limbs. It can result from various causes, including surgery where lymphatic vessels are removed or damaged, trauma, or conditions affecting lymphatic drainage.

In lymphedema, the obstruction or inadequate function of the lymphatic system prevents the normal transport and absorption of lymph, leading to the buildup of fluid. Understanding this term is crucial in both clinical coding and patient care, as it relates to various medical conditions and treatment pathways. Recognizing lymphedema's role in patient symptomatology aids in coding for management options related to the condition.
