The ICD-10-CM code for right upper quadrant tenderness is R10.811 (Right upper quadrant abdominal tenderness).

Within R10.81 (abdominal tenderness), R10.811 is specifically for right upper quadrant abdominal tenderness. Related codes cover left upper quadrant abdominal tenderness (R10.812), right lower quadrant abdominal tenderness (R10.813), left lower quadrant abdominal tenderness (R10.814), periumbilic abdominal tenderness (R10.815), epigastric abdominal tenderness (R10.816), generalized abdominal tenderness (R10.817) and unspecified site (R10.819).

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.
