The ulcers may be coded in M1 but don't rush yet to code it in M2 as stasis ulcers. Confirm if resident has a diagnosis of circulatory problems. In a weeping edema, there is a back up of pressure within the small veins and small arteries (capillaries). A
venous ulcer may be coded in M2 (Stasis) but not an
arterial ulcer.
This is a good guide in identifying leg ulcers,
http://www.wocn.org/publications/facts/pdf/C_QUICK1.pdf then have the MD confirm the type of ulcer. Unless the origin can be determined, it may not necessarily be the correct diagnosis. Until validated, the clinicians will address it as such.
The description of the affected areas on the left leg seem to fit the definition in M4d rather than M1 or M2. Maybe even a stasis dermatitis.
