ICD-10 code for hypotension
From the official ICD-10-CM alphabetic index entry “Hypotension (arterial) (constitutional)”. Page updated September 29, 2026.
About coding hypotension
The ICD-10-CM code for hypotension is I95.9 (Hypotension, unspecified). The official index lists 20 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I95.9.
Within I95, choose I95.9 (unspecified) only when documentation doesn't support a more specific option: idiopathic hypotension (I95.0), orthostatic hypotension (I95.1), due to drugs (I95.2), of hemodialysis (I95.3) and other hypotension (I95.8).
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.
