About coding urgency hypertension
The ICD-10-CM code for urgency hypertension is I16.0 (Hypertensive urgency).
Within I16 (hypertensive crisis), I16.0 is specifically for hypertensive urgency. Related codes cover emergency (I16.1) and unspecified (I16.9).
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 304 (Hypertension with MCC, relative weight 1.2011) and DRG 305 (Hypertension without MCC, relative weight 0.7581), 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.
