ICD-10 code for Nonvisualization

The ICD-10-CM code for Nonvisualization is R93.2 (Abnormal findings on diagnostic imaging of liver and biliary tract).

Within R93 (abnormal findings on diagnostic imaging of other body structures), R93.2 is specifically for abnormal findings on diagnostic imaging of liver and biliary tract. Related codes cover 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 other parts of digestive tract (R93.3), 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 444 (Disorders of the Biliary Tract with MCC, relative weight 1.6665), DRG 445 (Disorders of the Biliary Tract with CC, relative weight 1.0872) and DRG 446 (Disorders of the Biliary Tract without CC/MCC, relative weight 0.8124), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
