About R11.1

R11.1 is the ICD-10-CM diagnosis code for vomiting. It belongs to category R11 (nausea and vomiting), 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 7 subcodes must be used instead.

Within R11 (nausea and vomiting), R11.1 is specifically for vomiting. Related codes cover nausea (R11.0) and nausea with vomiting, unspecified (R11.2).

To report this condition, pick the subcode that matches the documentation: R11.10 (unspecified), R11.11 (without nausea), R11.12 (vomiting), R11.13 (of fecal matter), R11.14 (vomiting), R11.15 (migraine) and R11.16 (syndrome).

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