About coding renovascular hypertension
The ICD-10-CM code for renovascular hypertension is I15.0 (Renovascular hypertension).
Within I15 (secondary hypertension), I15.0 is specifically for renovascular hypertension. Related codes cover hypertension secondary to other renal disorders (I15.1), hypertension secondary to endocrine disorders (I15.2), other secondary hypertension (I15.8) and unspecified (I15.9).
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.
