About coding venous pressure increase
The ICD-10-CM code for venous pressure increase is I87.8 (Other specified disorders of veins). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on I87.8.
Within I87, choose I87.8 (Other specified disorders of veins) only when documentation doesn't support a more specific option: Postthrombotic syndrome (I87.0), compression of vein (I87.1), venous insufficiency (chronic) (peripheral) (I87.2), chronic venous hypertension (idiopathic) (I87.3) and disorder of vein, unspecified (I87.9).
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 302 (Atherosclerosis with MCC, relative weight 1.1984) and DRG 303 (Atherosclerosis without MCC, relative weight 0.6612), 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.
