R19.09Other intra-abdominal and pelvic swelling, mass and lump

R19.09 is the ICD-10-CM diagnosis code for other 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R19.0, choose R19.09 (Other intra-abdominal and pelvic swelling, mass and lump) only when documentation doesn't support a more specific option: unspecified site (R19.00), right upper quadrant abdominal swelling, mass and lump (R19.01), left upper quadrant abdominal swelling, mass and lump (R19.02), right lower quadrant abdominal swelling, mass and lump (R19.03), left lower quadrant abdominal swelling, mass and lump (R19.04), periumbilic swelling, mass or lump (R19.05), epigastric swelling, mass or lump (R19.06) and generalized intra-abdominal and pelvic swelling, mass and lump (R19.07).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

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

Before ICD-10, this condition was coded in ICD-9-CM as 789.39 (abdominal or pelvic swelling, mass, or lump, other specified site).
