About coding feces abnormal
The ICD-10-CM code for feces abnormal is R19.5 (Other fecal abnormalities).
Within R19, choose R19.5 (Other fecal abnormalities) only when documentation doesn't support a more specific option: intra-abdominal and pelvic swelling, mass and lump (R19.0), abnormal bowel sounds (R19.1), visible peristalsis (R19.2), abdominal rigidity (R19.3), change in bowel habit (R19.4), Halitosis (R19.6), diarrhea, unspecified (R19.7) and other specified symptoms and signs involving the digestive system and abdomen (R19.8).
Don't report R19.5 together with the conditions in its Excludes1 note: melena (K92.1) and neonatal melena (P54.1).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for R19.5)
