Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the D73 range.
Hypersplenism
Condition characterized by splenomegaly, some reduction in the number of circulating blood cells in the presence of a normal or hyperactive bone marrow, and the potential for reversal by splenectomy.
Splenosis
The spontaneous transplantation of splenic tissue to unusual sites after open splenic trauma, e.g., after automobile accidents, gunshot or stab wounds. The splenic pulp implants appear as red-blue nodules on the peritoneum, omentum, and mesentery, morphologically similar to multifocal pelvic endometriosis. (Segen, Dictionary of Modern Medicine, 1992)
Wandering Spleen
A congenital or acquired condition in which the SPLEEN is not in its normal anatomical position but moves about in the ABDOMEN. This is due to laxity or absence of suspensory ligaments which normally provide peritoneal attachments to keep the SPLEEN in a fixed position. Clinical symptoms include ABDOMINAL PAIN, splenic torsion and ISCHEMIA.
About the D73 Code Range
These spleen diseases include chronic congestive enlargement, abscesses, cysts, and infarction. The category also distinguishes hyposplenism from hypersplenism.
D73.0 and D73.1 name hyposplenism and hypersplenism. D73.2 identifies chronic congestive spleen enlargement. Separate subdivisions identify an abscess, a cyst, and infarction: D73.3, D73.4, and D73.5. The other-disease branch, D73.8, separates neutropenic spleen enlargement (D73.81) from other spleen diseases (D73.89). D73.9 identifies an unspecified spleen disease.
