The landscape of the district is mostly mountainous. The Nera Plateau and the Tas-Kystabyt are located in the northwestern part of the district.

The district was established on December 2, 1953.

Within the framework of administrative divisions, Susumansky District is one of the eight in the oblast. The town of Susuman serves as its administrative center.

As a municipal division, the district has been incorporated as Susumansky Urban Okrug since May 1, 2015. Prior to that date, the district was incorporated as Susumansky Municipal District, which was subdivided into three urban settlements and one rural settlement.

The main industries in the district are gold and coal mining. Despite being rich in natural resources, the district economy suffered in the first decades of the 2000s. The severe climate and poorly developed infrastructure are partly to blame, but the difficult transition from Soviet times has led to the collapse of a number of companies with the result that many inhabitants have left the region.
