R19.0Intra-abdominal and pelvic swelling, mass and lump

R19.0 is the ICD-10-CM diagnosis code for intra-abdominal and pelvic swelling, mass and lump. It belongs to category R19 (other symptoms and signs involving the digestive system and abdomen), 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.

Within R19 (other symptoms and signs involving the digestive system and abdomen), R19.0 is specifically for intra-abdominal and pelvic swelling, mass and lump. Related codes cover abnormal bowel sounds (R19.1), visible peristalsis (R19.2), abdominal rigidity (R19.3), change in bowel habit (R19.4), other fecal abnormalities (R19.5), Halitosis (R19.6), diarrhea, unspecified (R19.7) and other specified symptoms and signs involving the digestive system and abdomen (R19.8).

To report this condition, pick the subcode that matches the documentation: R19.00 (unspecified site), R19.01 (lump), R19.02 (lump), R19.03 (lump), R19.04 (lump), R19.05 (lump), R19.06 (lump), R19.07 (lump) and 1 more.

Don't report R19.0 together with the conditions in its Excludes1 note: abdominal distension (gaseous) (R14.-) and ascites (R18.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
