About K52.83

K52.83 is the ICD-10-CM diagnosis code for microscopic colitis. It belongs to category K52 (other and unspecified noninfective gastroenteritis and colitis), block K50-K52 (noninfective enteritis and colitis) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within K52.8 (other specified noninfective gastroenteritis and colitis), K52.83 is specifically for microscopic colitis. Related codes cover eosinophilic gastritis or gastroenteritis (K52.81), eosinophilic colitis (K52.82) and other specified noninfective gastroenteritis and colitis (K52.89).

To report this condition, pick the subcode that matches the documentation: K52.831 (colitis), K52.832 (colitis), K52.838 (colitis) and K52.839 (unspecified).

It was added in FY2017, effective October 1, 2016.
