The upper reaches of the river are in Omsukchansky District, then it flows across the Srednekansky District in its lower course. The name of the river originated in the Northern Yukaghir language.

The Korkodon is the fifth longest tributary of the Kolyma and the third in basin area. It has its sources in the Korkodon Range of the Kolyma Mountains. It heads first roughly northwards within a swampy valley between the Korkodon Range to the west and the Molkaty and Kongin ranges to the east. Halfway through its course it bends and flows west and then southwestwards, fringing the Yukaghir Highlands. In its lower course it meanders and flows through a wide flat valley. Finally the river joins the right bank of the Kolyma  from its mouth at an elevation of . The Korkodon has some very long tributaries. The most important ones are the  long Bulun and the  long Bolshoy Yarkodon from the right; and the  long Pungali and the  long Biliriken from the left. There are over 1,100 lakes in the Korkodon basin, most of them of the thermokarst type (alas), as well as swamps. The river freezes between mid October and mid May, but polynyas may form in the lower reaches. Fauna
