R19.03 ICD-10-CM Code: Right lower quadrant abdominal swelling, mass and lump

R19.03 is the ICD-10-CM diagnosis code for right lower quadrant abdominal swelling, mass and lump. A swelling, mass, or lump detected in the right lower portion of the abdomen, typically where the appendix and right colon are located. R19.03 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering symptoms and signs involving the digestive system and abdomen (r10-r19).

R19.03 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
