About coding Echocardiogram abnormal

The ICD-10-CM code for Echocardiogram abnormal is R93.1 (Abnormal findings on diagnostic imaging of heart and coronary circulation).

Within R93 (abnormal findings on diagnostic imaging of other body structures), R93.1 is specifically for abnormal findings on diagnostic imaging of heart and coronary circulation. Related codes cover abnormal findings on diagnostic imaging of skull and head, not elsewhere classified (R93.0), abnormal findings on diagnostic imaging of liver and biliary tract (R93.2), 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 302 (Atherosclerosis with MCC, relative weight 1.1984) and DRG 303 (Atherosclerosis without MCC, relative weight 0.6612), in MDC 05 (Diseases and Disorders of the Circulatory 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.
