About coding Vectorcardiogram abnormal
The ICD-10-CM code for Vectorcardiogram abnormal is R94.39 (Abnormal result of other cardiovascular function study).
Within R94.3, choose R94.39 (result of other cardiovascular function study) only when documentation doesn't support a more specific option: result of cardiovascular function study, unspecified (R94.30) and electrocardiogram [ECG] [EKG] (R94.31).
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 314 (Other Circulatory System Diagnoses with MCC, relative weight 2.0873), DRG 315 (Other Circulatory System Diagnoses with CC, relative weight 0.9508) and DRG 316 (Other Circulatory System Diagnoses without CC/MCC, relative weight 0.6677), 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.
