Clinical Information

• Lichen Planus-. an inflammatory, pruritic disease of the skin and mucous membranes, which can be either generalized or localized. it is characterized by distinctive purplish, flat-topped papules having a predilection for the trunk and flexor surfaces. the lesions may be discrete or coalesce to form plaques. histologically, there is a "saw-tooth" pattern of epidermal hyperplasia and vacuolar alteration of the basal layer of the epidermis along with an intense upper dermal inflammatory infiltrate composed predominantly of t-cells. etiology is unknown.
• Lichen Planus, Oral-. oral lesions accompanying cutaneous lichen planus or often occurring alone. the buccal mucosa, lips, gingivae, floor of the mouth, and palate are usually affected (in a descending order of frequency). typically, oral lesions consist of radiating white or gray, velvety, threadlike lines, arranged in a reticular pattern, at the intersection of which there may be minute, white, elevated dots or streaks (wickham's striae). (jablonski, illustrated dictionary of dentistry)
• Atrophic Lichen Planus-. a rare form of lichen planus that is characterized by well-demarcated, white-bluish papules or plaques with central atrophy.
• Bullous Lichen Planus-. a rare form of lichen planus that is characterized by the formation of vesico-bullous lesions on top of preexisting lichen planus papules or on normal skin.
• Hypertrophic Lichen Planus-. a form of lichen planus that is characterized by plaques of markedly thickened skin that is often extremely pruritic and localized to the lower legs. it can result in permanent pigmentation and scarring.
• Lichen Planus-. a chronic, recurrent, pruritic inflammatory disorder of unknown etiology that affects the skin and mucus membranes. it presents with rashes and papules that tend to resolve spontaneously. it may be associated with hepatitis c. certain drugs that contain arsenic or bismuth are associated with reactions mimicking lichen planus.
• Lichen Planus-Like Keratosis|Lichenoid Keratosis-. a benign intraepidermal squamoproliferative neoplasm characterized by irregular acanthosis, hyperkeratosis, parakeratosis, and prominent chronic inflammation.
• Lichenoid Drug Eruption|Drug-induced Lichen Planus|Drug-induced Lichen Planus-. a red or violaceous flat-topped, papular eruption that is induced by exposure to a variety of medications or environmental agents.
• Oral Lichen Planus-. a chronic, autoimmune inflammatory condition of the mucous membranes in the oral cavity that affects approximately two percent of the population and is most often seen in middle aged women. it is characterized by white, lacy patches; red, swollen tissue; papules and plaques; or open sores. the lesions are typically bilateral.

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.
