R10.1Pain localized to upper abdomen

R10.1 is the ICD-10-CM diagnosis code for pain localized to upper abdomen. It belongs to category R10 (abdominal and pelvic pain), 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 4 subcodes must be used instead.

Within R10 (abdominal and pelvic pain), R10.1 is specifically for pain localized to upper abdomen. Related codes cover acute abdomen (R10.0), pelvic and perineal pain (R10.2), pain localized to other parts of lower abdomen (R10.3), other abdominal pain (R10.8), unspecified abdominal pain (R10.9) and pain localized to flank (R10.A).

To report this condition, pick the subcode that matches the documentation: R10.10 (unspecified), R10.11 (pain), R10.12 (pain) and R10.13 (pain).

The conditions in its Excludes2 note aren't part of R10.1, but may be coded alongside it if the patient has both: pain localized to flank (R10.A-) and pelvic and perineal pain (R10.2-).

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