Clinical Information

• Acrodermatitis

  inflammation involving the skin of the extremities, especially the hands and feet. several forms are known, some idiopathic and some hereditary. the infantile form is called gianotti-crosti syndrome.

• Acrodynia

  a condition seen primarily in childhood, most often resulting from chronic exposure to mercury compounds which may result in encephalopathy and polyneuropathy. clinical features include pain, swelling and pinkish discoloration of the fingers and toes, weakness in the extremities, extreme irritability, hyperesthesia, and alterations in level of consciousness. (from menkes, textbook of child neurology, 5th ed, p603)

• Bloom Syndrome

  an autosomal recessive disorder characterized by telangiectatic erythema of the face, photosensitivity, dwarfism and other abnormalities, and a predisposition toward developing cancer. the bloom syndrome gene (blm) encodes a recq-like dna helicase.

• Erythema

  redness of the skin produced by congestion of the capillaries. this condition may result from a variety of disease processes.

• Erythema Ab Igne

  a cutaneous finding caused by prolonged heat exposure (e.g., space heater) and local heat injury (e.g., caused by laser therapy). it is characterized by epidermal atrophy, reticular hyperpigmentation, and telangiectatic dermatosis.

• Erythema Chronicum Migrans

  a deep type of gyrate erythema that follows a bite by an ixodid tick; it is a stage-1 manifestation of lyme disease. the site of the bite is characterized by a red papule that expands peripherally as a nonscaling, palpable band that clears centrally. this condition is often associated with systemic symptoms such as chills, fever, headache, malaise, nausea, vomiting, fatigue, backache, and stiff neck.

• Erythema Induratum

  a type of panniculitis characterized histologically by the presence of granulomas, vasculitis, and necrosis. it is traditionally considered to be the tuberculous counterpart of nodular vasculitis, but is now known to occur without tuberculous precedent. it is seen most commonly in adolescent and menopausal women, is initiated or exacerbated by cold weather, and typically presents as one or more recurrent erythrocyanotic nodules or plaques on the calves. the nodules may progress to form indurations, ulcerations, and scars.

• Erythema Infectiosum

  contagious infection with human b19 parvovirus most commonly seen in school age children and characterized by fever, headache, and rashes of the face, trunk, and extremities. it is often confused with rubella.

• Erythema Multiforme

  a skin and mucous membrane disease characterized by an eruption of macules, papules, nodules, vesicles, and/or bullae with characteristic "bull's-eye" lesions usually occurring on the dorsal aspect of the hands and forearms.

• Erythema Nodosum

  an erythematous eruption commonly associated with drug reactions or infection and characterized by inflammatory nodules that are usually tender, multiple, and bilateral. these nodules are located predominantly on the shins with less common occurrence on the thighs and forearms. they undergo characteristic color changes ending in temporary bruise-like areas. this condition usually subsides in 3-6 weeks without scarring or atrophy.

• Glossitis, Benign Migratory

  an idiopathic disorder of the tongue characterized by the loss of filiform papillae leaving reddened areas of circinate macules bound by a white band. the lesions heal, then others erupt.

• Necrolytic Migratory Erythema

  recurrent cutaneous manifestation of glucagonoma characterized by necrolytic polycyclic migratory lesions with scaling borders. it is associated with elevated secretion of glucagon by the tumor. other conditions with elevated serum glucagon levels such as hepatic cirrhosis may also result in similar skin lesions, which are referred to as pseudoglucagonoma syndrome.

• Rosacea

  a cutaneous disorder primarily of convexities of the central part of the face, such as forehead; cheek; nose; and chin. it is characterized by flushing; erythema; edema; rhinophyma; papules; and ocular symptoms. it may occur at any age but typically after age 30. there are various subtypes of rosacea: erythematotelangiectatic, papulopustular, phymatous, and ocular (national rosacea society's expert committee on the classification and staging of rosacea, j am acad dermatol 2002; 46:584-7).

• Laser Therapy

  the use of photothermal effects of lasers to coagulate, incise, vaporize, resect, dissect, or resurface tissue.

• Lyme Disease

  an infectious disease caused by a spirochete, borrelia burgdorferi, which is transmitted chiefly by ixodes dammini (see ixodes) and pacificus ticks in the united states and ixodes ricinis (see ixodes) in europe. it is a disease with early and late cutaneous manifestations plus involvement of the nervous system, heart, eye, and joints in variable combinations. the disease was formerly known as lyme arthritis and first discovered at old lyme, connecticut.

• Rubella

  an acute infectious disease caused by the rubella virus. the virus enters the respiratory tract via airborne droplet and spreads to the lymphatic system.

L53.9 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
606	MINOR SKIN DISORDERS WITH MCC	09	1.5858
607	MINOR SKIN DISORDERS WITHOUT MCC	09	0.8935

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Patient Education

Skin Conditions

What does your skin do?

Your skin is your body's largest organ. It covers the entire outside of your body. There are many ways that your skin protects your body and helps keep you healthy. For example, it:

• Holds body fluids in, which helps prevent you from getting dehydrated
• Keeps out harmful germs, which helps prevent infections
• Helps you feel things like heat, cold, and pain
• Helps control your body temperature
• Makes vitamin D when the sun shines on it
• Shields your body against heat and light

What problems and conditions can affect your skin?

There are many different problems and conditions which can affect your skin. Some of them can cause uncomfortable symptoms, such as itching, burning, redness, and rashes. They might also affect your appearance. Some of the more common skin conditions include:

• Acne, which causes pimples when hair follicles under your skin get clogged up
• Burns
• Cuts and scrapes
• Dandruff, flaking of the skin on your scalp (the top of your head)
• Eczema (atopic dermatitis), which causes inflammation, redness, and irritation of the skin
• Hives, which are red and sometimes itchy bumps on your skin
• Insect bites
• Psoriasis, which causes itchy, scaly red patches
• Skin cancer
• Skin infections

How can I keep my skin healthy?

Since your skin protects your body in many ways, it's important to try to keep your skin healthy. For example, you can:

• Wear the right protective equipment, like gloves, long sleeves, knee and elbow pads, or helmets to protect against cuts, bumps and scrapes.
• If you do get a cut or scrape, clean it right away with soap and warm water. Put on a bandage to protect it while it heals.
• When you are spending time outdoors, wear long sleeves and pants and use insect repellant to prevent insect bites.
• Prevent sunburn by covering up and using sunscreen when outdoors.
• Wash your hands often with soap and water.
• When you take a shower or bath, use warm (not hot) water. Use mild cleansers and wash gently (don't scrub).
• Use moisturizers, like lotions, creams, or ointments, to prevent dry skin.
