About I73.8
I73.8 is the ICD-10-CM diagnosis code for other specified peripheral vascular diseases. It belongs to category I73 (other peripheral vascular diseases), block I70-I79 (diseases of arteries, arterioles and capillaries) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.
Within I73, choose I73.8 (Other specified peripheral vascular diseases) only when documentation doesn't support a more specific option: Raynaud's syndrome (I73.0), Thromboangiitis obliterans [Buerger's disease] (I73.1) and peripheral vascular disease, unspecified (I73.9).
To report this condition, pick the subcode that matches the documentation: I73.81 (Erythromelalgia) and I73.89 (diseases).
Don't report I73.8 together with the conditions in its Excludes1 note: diabetic (peripheral) angiopathy (E08-E13 with .51-.52).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
