About R19
R19 is the ICD-10-CM diagnosis code for other symptoms and signs involving the digestive system and abdomen. It belongs to block R10-R19 (symptoms and signs involving the digestive system and abdomen) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: R19.0 (lump), R19.1 (sounds), R19.2 (peristalsis), R19.3 (rigidity), R19.4 (habit), R19.5 (abnormalities), R19.6 (Halitosis), R19.7 (unspecified) and 1 more.
Don't report R19 together with the conditions in its Excludes1 note: acute abdomen (R10.0).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
