About K29.7
K29.7 is the ICD-10-CM diagnosis code for gastritis, unspecified. It belongs to category K29 (gastritis and duodenitis), block K20-K31 (diseases of esophagus, stomach and duodenum) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.
Within K29, choose K29.7 (Gastritis, unspecified) only when documentation doesn't support a more specific option: acute gastritis (K29.0), alcoholic gastritis (K29.2), chronic superficial gastritis (K29.3), chronic atrophic gastritis (K29.4), unspecified chronic gastritis (K29.5), other gastritis (K29.6), duodenitis (K29.8) and gastroduodenitis, unspecified (K29.9).
To report this condition, pick the subcode that matches the documentation: K29.70 (without bleeding) and K29.71 (with bleeding).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
