About coding vena cava stenosis
The ICD-10-CM code for vena cava stenosis is I87.1 (Compression of vein). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on I87.1.
Within I87 (other disorders of veins), I87.1 is specifically for compression of vein. Related codes cover Postthrombotic syndrome (I87.0), venous insufficiency (chronic) (peripheral) (I87.2), chronic venous hypertension (idiopathic) (I87.3), other specified disorders of veins (I87.8) and disorder of vein, unspecified (I87.9).
The conditions in its Excludes2 note aren't part of I87.1, but may be coded alongside it if the patient has both: compression of pulmonary vein (I28.8).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
