About R93.89

R93.89 is the ICD-10-CM diagnosis code for abnormal findings on diagnostic imaging of other specified body structures. It belongs to category R93 (abnormal findings on diagnostic imaging of other body structures), block R90-R94 (abnormal findings on diagnostic imaging and in function studies, without diagnosis) 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 R93.8, choose R93.89 (findings on diagnostic imaging of other specified body structures) only when documentation doesn't support a more specific option: radiologic findings on diagnostic imaging of testis (R93.81).

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 947 (Signs and Symptoms with MCC, relative weight 1.261) and DRG 948 (Signs and Symptoms without MCC, relative weight 0.7835), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), 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 was added in FY2019, effective October 1, 2018.
