The spleen is an organ that filters the blood and removes old red blood cells.
DC 7706: If the spleen is completely or partially removed, then it is rated 20%.
DC 7707: All other spleen conditions are rated under this code. This code does not have its own rating system but is rated on the main symptoms the spleen condition causes. So if the spleen does not filter properly and causes a heart condition, then it would be rated under that heart condition.
