Clinical Information

• Pallor-. a clinical manifestation consisting of an unnatural paleness of the skin.
• Livedo Reticularis-. a condition characterized by a reticular or fishnet pattern on the skin of lower extremities and other parts of the body. this red and blue pattern is due to deoxygenated blood in unstable dermal blood vessels. the condition is intensified by cold exposure and relieved by rewarming.
• Livedoid Vasculopathy-. a rare cutaneous thrombotic disease due to occlusion of dermal vessels. it is characterized by purpuric maculae and ulcerations especially during summer which form scars called atrophie blanche. it is more associated with other syndromes (e.g., protein c deficiency; hyperhomocysteinemia).
• Sneddon Syndrome-. a systemic non-inflammatory arteriopathy primarily of middle-aged females characterized by the association of livedo reticularis, multiple thrombotic cerebral infarction; coronary disease, and hypertension. elevation of antiphospholipid antibody titers (see also antiphospholipid syndrome), cardiac valvulopathy, ischemic attack, transient; seizures; dementia; and chronic ischemia of the extremities may also occur. pathologic examination of affected arteries reveals non-inflammatory adventitial fibrosis, thrombosis, and changes in the media. (from jablonski, dictionary of syndromes & eponymic diseases, 2d ed; adams et al., principles of neurology, 6th ed, p861; arch neurol 1997 jan;54(1):53-60)
• Livedo Reticularis-. a recurrent purple discoloration of the skin that does not blanche and is found in a lacy, network pattern, most often in the lower extremities. it may be aggravated by exposure to cold and is classified as idiopathic or secondary. secondary livedo reticularis may be a cutaneous manifestation of immune system disorders (e.g., lupus erythematosus, rheumatoid arthritis, cryoglobulinemia, lymphoma, etc), and hematologic disorders (polycythemia vera).

Diagnostic Related Groups - MS-DRG Mapping

The is diagnosis code is grouped in the following groups for version MS-DRG V40.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2022 through 09/30/2023.

Skin Conditions

Your skin is your body's largest organ. It covers and protects your body. Your skin:

• Holds body fluids in, preventing dehydration
• Keeps harmful microbes out, preventing infections
• Helps you feel things like heat, cold, and pain
• Keeps your body temperature even
• Makes vitamin D when the sun shines on it

Anything that irritates, clogs, or inflames your skin can cause symptoms such as redness, swelling, burning, and itching. Allergies, irritants, your genetic makeup, and certain diseases and immune system problems can cause rashes, hives, and other skin conditions. Many skin problems, such as acne, also affect your appearance.
