About coding Angiospastic edema
The ICD-10-CM code for Angiospastic edema is I73.9 (Peripheral vascular disease, unspecified).
Within I73, choose I73.9 (Peripheral vascular disease, unspecified) only when documentation doesn't support a more specific option: Raynaud's syndrome (I73.0), Thromboangiitis obliterans [Buerger's disease] (I73.1) and other specified peripheral vascular diseases (I73.8).
Don't report I73.9 together with the conditions in its Excludes1 note: atherosclerosis of the extremities (I70.2--I70.7-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for I73.9)
