D70-D77: Other diseases of blood and blood-forming organs
D73: Diseases of spleen
Diseases of the spleen, classified under the ICD-10 code D73, form a group of conditions that affect the spleen, an organ located on the left side of the abdomen beneath the rib cage. The spleen plays crucial roles in the immune system and blood filtration. These diseases may have various causes including infections, blood clots, or direct damage to the spleen itself. Common conditions under this category include splenic sequestration crises, where blood gets trapped in the spleen, and hypersplenism, a condition characterized by an overly active spleen that destroys blood cells. Symptoms associated with diseases of the spleen majorly consist of pain or discomfort in the upper left part of the abdomen, anemia, fatigue, frequent infections, and easy bleeding. As these diseases progress, they may affect the immune system and cause complications such as infections and blood disorders.
