About coding duodenum filling defect
The ICD-10-CM code for duodenum filling defect is R93.3 (Abnormal findings on diagnostic imaging of other parts of digestive tract).
Within R93, choose R93.3 (Abnormal findings on diagnostic imaging of other parts of digestive tract) only when documentation doesn't support a more specific option: abnormal findings on diagnostic imaging of skull and head, not elsewhere classified (R93.0), abnormal findings on diagnostic imaging of heart and coronary circulation (R93.1), abnormal findings on diagnostic imaging of liver and biliary tract (R93.2), abnormal findings on diagnostic imaging of urinary organs (R93.4), abnormal findings on diagnostic imaging of other abdominal regions, including retroperitoneum (R93.5), abnormal findings on diagnostic imaging of limbs (R93.6), abnormal findings on diagnostic imaging of other parts of musculoskeletal system (R93.7), abnormal findings on diagnostic imaging of other specified body structures (R93.8) and 1 more.
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.
