Code Classification

  • Diseases of the skin and subcutaneous tissue
    (L00–L99)
    • Dermatitis and eczema
      (L20-L30)
      • Other and unspecified dermatitis
        (L30)

L30.9 is a billable diagnosis code used to specify a medical diagnosis of dermatitis, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like L30.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Information

  • Acne Keloid

    a type of acneiform disorder in which secondary pyogenic infection in and around pilosebaceous structures ends in keloidal scarring. it manifests as persistent folliculitis of the back of the neck associated with occlusion of the follicular orifices. it is most often encountered in black or asian men.
  • Chromoblastomycosis

    scaly papule or warty growth, caused by five fungi, that spreads as a result of satellite lesions affecting the foot or leg. the extremity may become swollen and, at its distal portion, covered with various nodular, tumorous, verrucous lesions that resemble cauliflower. in rare instances, the disease may begin on the hand or wrist and involve the entire upper extremity. (arnold, odom, and james, andrew's diseases of the skin, 8th ed, p362)
  • Dermatitis

    any inflammation of the skin.
  • Dermatitis Herpetiformis

    rare, chronic, papulo-vesicular disease characterized by an intensely pruritic eruption consisting of various combinations of symmetrical, erythematous, papular, vesicular, or bullous lesions. the disease is strongly associated with the presence of hla-b8 and hla-dr3 antigens. a variety of different autoantibodies has been detected in small numbers in patients with dermatitis herpetiformis.
  • Dermatitis, Allergic Contact

    a contact dermatitis due to allergic sensitization to various substances. these substances subsequently produce inflammatory reactions in the skin of those who have acquired hypersensitivity to them as a result of prior exposure.
  • Dermatitis, Atopic

    a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (ige), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. it is manifested by lichenification, excoriation, and crusting, mainly on the flexural surfaces of the elbow and knee. in infants it is known as infantile eczema.
  • Dermatitis, Contact

    a type of acute or chronic skin reaction in which sensitivity is manifested by reactivity to materials or substances coming in contact with the skin. it may involve allergic or non-allergic mechanisms.
  • Dermatitis, Exfoliative

    the widespread involvement of the skin by a scaly, erythematous dermatitis occurring either as a secondary or reactive process to an underlying cutaneous disorder (e.g., atopic dermatitis, psoriasis, etc.), or as a primary or idiopathic disease. it is often associated with the loss of hair and nails, hyperkeratosis of the palms and soles, and pruritus. (from dorland, 27th ed)
  • Dermatitis, Irritant

    a non-allergic contact dermatitis caused by prolonged exposure to irritants and not explained by delayed hypersensitivity mechanisms.
  • Dermatitis, Occupational

    a recurrent contact dermatitis caused by substances found in the work place.
  • Dermatitis, Perioral

    a papular eruption of unknown etiology that progresses to residual papular erythema and scaling usually confined to the area of the mouth, and almost exclusively occurring in young women. it may also be localized or extend to involve the eyelids and adjacent glabella area of the forehead (periocular dermatitis). (dorland, 28th ed)
  • Dermatitis, Photoallergic

    a delayed hypersensitivity involving the reaction between sunlight or other radiant energy source and a chemical substance to which the individual has been previously exposed and sensitized. it manifests as a papulovesicular, eczematous, or exudative dermatitis occurring chiefly on the light-exposed areas of the skin.
  • Dermatitis, Phototoxic

    a nonimmunologic, chemically induced type of photosensitivity producing a sometimes vesiculating dermatitis. it results in hyperpigmentation and desquamation of the light-exposed areas of the skin.
  • Dermatitis, Seborrheic

    a chronic inflammatory disease of the skin with unknown etiology. it is characterized by moderate erythema, dry, moist, or greasy (sebaceous gland) scaling and yellow crusted patches on various areas, especially the scalp, that exfoliate as dandruff. seborrheic dermatitis is common in children and adolescents with hiv infections.
  • Dermatitis, Toxicodendron

    an allergic contact dermatitis caused by exposure to plants of the genus toxicodendron (formerly rhus). these include poison ivy, poison oak, and poison sumac, all plants that contain the substance urushiol, a potent skin sensitizing agent. (from dorland, 27th ed)
  • Digital Dermatitis

    highly contagious infectious dermatitis with lesions near the interdigital spaces usually in cattle. it causes discomfort and often severe lameness (lameness, animal). lesions can be either erosive or proliferative and wart-like with papillary growths and hypertrophied hairs. dichelobacter nodosus and treponema are the most commonly associated causative agents for this mixed bacterial infection disease.
  • Drug Eruptions

    adverse cutaneous reactions caused by ingestion, parenteral use, or local application of a drug. these may assume various morphologic patterns and produce various types of lesions.
  • Ecthyma, Contagious

    an infectious dermatitis of sheep and goats, affecting primarily the muzzle and lips. it is caused by a poxvirus and may be transmitted to man.
  • Eczema

    a pruritic papulovesicular dermatitis occurring as a reaction to many endogenous and exogenous agents (dorland, 27th ed).
  • Nicolau Syndrome

    an uncommon complication of intramuscular injection leading to variable degrees of necrosis of skin and underlying tissue.
  • Photosensitivity Disorders

    abnormal responses to sunlight or artificial light due to extreme reactivity of light-absorbing molecules in tissues. it refers almost exclusively to skin photosensitivity, including sunburn, reactions due to repeated prolonged exposure in the absence of photosensitizing factors, and reactions requiring photosensitizing factors such as photosensitizing agents and certain diseases. with restricted reference to skin tissue, it does not include photosensitivity of the eye to light, as in photophobia or photosensitive epilepsy.
  • Radiodermatitis

    a cutaneous inflammatory reaction occurring as a result of exposure to ionizing radiation.
  • Dual Specificity Phosphatase 3

    a dual specificity phosphatase subtype that plays a role in intracellular signal transduction by inactivating mitogen-activated protein kinases. it has specificity for extracellular signal-regulated map kinases.
  • Smallpox Vaccine

    a vaccinia virus vaccine used for immunization against smallpox. it is now recommended only for laboratory workers exposed to smallpox virus. certain countries continue to vaccinate those in the military service. rare complications most often associated with older generation smallpox vaccines include vaccinia, secondary bacterial infections, and encephalomyelitis. because monkeypox virus and smallpox virus are both orthopoxvirus and are closely related smallpox vaccines provide effective cross-protection against monkeypox (https://www.cdc.gov/poxvirus/monkeypox/clinicians/smallpox-vaccine.html).
  • Vaccinia

    the cutaneous and occasional systemic reactions associated with vaccination using smallpox (variola) vaccine.
  • Vaccinia virus

    the type species of orthopoxvirus, related to cowpox virus, but whose true origin is unknown. it has been used as a live vaccine against smallpox. it is also used as a vector for inserting foreign dna into animals. rabbitpox virus is a subspecies of vaccinia virus.
  • Eczema, Dyshidrotic

    a recurrent eczematous reaction characterized by the development of vesicular eruptions on the palms and soles, particularly along the sides and between the digits. it is accompanied by pruritus, a burning sensation, and hyperhidrosis. the disease is self-limiting, lasting only a few weeks. (dorland, 27th ed)
  • Kaposi Varicelliform Eruption

    a disseminated vesicular-pustular eruption caused by the herpes simplex virus (herpesvirus hominis), the vaccinia virus, or varicella zoster (herpesvirus 3, human). it is usually superimposed on a preexisting, inactive or active, atopic dermatitis (dermatitis, atopic).
  • Skin Diseases, Eczematous

    any of a variety of eruptive skin disorders characterized by erythema, oozing, vesiculation, and scaling. etiology is varied.
  • Wiskott-Aldrich Syndrome

    a rare, x-linked immunodeficiency syndrome characterized by eczema; lymphopenia; and, recurrent pyogenic infection. it is seen exclusively in young boys. typically, immunoglobulin m levels are low and immunoglobulin a and immunoglobulin e levels are elevated. lymphoreticular malignancies are common.
  • Injections, Intramuscular

    forceful administration into a muscle of liquid medication, nutrient, or other fluid through a hollow needle piercing the muscle and any tissue covering it.
  • GMSS Version Type 1 Diabetes - Too Many Skin Irritations/Bruises|GMSS01-Too Many Skin Irritations/Bruises|GMSS01-Too Many Skin Irritations/Bruises|GMSS0111

    the glucose monitoring satisfaction survey version: type 1 diabetes (gmss version type 1 diabetes) my current monitor: causes too many skin irritations or bruises.

Patient Education


Rashes

A rash is an area of irritated or swollen skin. Many rashes are itchy, red, painful, and irritated. Some rashes can also lead to blisters or patches of raw skin. Rashes are a symptom of many different medical problems. Other causes include irritating substances and allergies. Certain genes can make people more likely to get rashes.

Contact dermatitis is a common type of rash. It causes redness, itching, and sometimes small bumps. You get the rash where you have touched an irritant, such as a chemical, or something you are allergic to, like poison ivy.

Some rashes develop right away. Others form over several days. Although most rashes clear up fairly quickly, others are long-lasting and need long-term treatment.

Because rashes can be caused by many different things, it's important to figure out what kind you have before you treat it. If it is a bad rash, if it does not go away, or if you have other symptoms, you should see your health care provider. Treatments may include moisturizers, lotions, baths, cortisone creams that relieve swelling, and antihistamines, which relieve itching.

Atopic Dermatitis

Atopic dermatitis, often called eczema, is a chronic (long-lasting) disease that causes the skin to become inflamed and irritated, making it extremely itchy.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
