Atopic Dermatitis

As a physician or coder, accurately selecting ICD-10 coding for atopic dermatitis is essential for proper reporting, reimbursement, and data collection.

Understanding Atopic Dermatitis and Its Diagnosis

To properly diagnose atopic dermatitis, physicians consider both clinical features as well as results from allergy testing. Clinically, atopic dermatitis presents as chronically relapsing skin inflammation with severe pruritus (itching).

The diagnostic criteria for atopic dermatitis includes:

  • Pruritus: Persistent or chronically relapsing itchiness of the skin.
  • Eczematous lesions: Skin rashes like erythema (redness), papules (bumps), vesicles (blisters), excoriations (scratches), and lichenification (skin thickening) in characteristic locations (face, neck, wrists, ankles, etc.).
  • Chronic or relapsing history: Patient history shows the condition has persisted or recurred for at least 6 months.
  • Personal or family history of atopic disease: The patient or close family members have a history of atopic dermatitis, allergic rhinitis, asthma, or other atopic diseases.
  • Increased serum IgE: Elevated levels of immunoglobulin E (IgE) in the blood, especially to common environmental and food allergens.

The Importance of Accurate ICD-10 Coding for Atopic Dermatitis

Accurate ICD-10 coding is essential for proper diagnosis and treatment of atopic dermatitis. The ICD-10 code identifies the condition and helps determine appropriate therapeutic approaches. Correct coding also enables correct billing and reimbursement.

Choose the Most Specific Code

There are several ICD-10 codes for atopic dermatitis, ranging from non-specific to very specific. Choose the code that most accurately reflects the patient’s condition based on the signs, symptoms, test results, and other factors. For example, code L20.9, “Atopic dermatitis, unspecified,” would be too non-specific, while L20.82, “Intrinsic (allergic) atopic dermatitis,” pinpoints the subtype. Using a more precise code leads to better treatment.

Consider Disease Severity

The severity of a patient’s atopic dermatitis must be considered when choosing an ICD-10 code. Codes specify whether the condition is mild, moderate or severe. For instance, code L20.0 indicates “Besnier’s prurigo: atopic dermatitis of eyelids,” while L20.1 denotes “Atopic dermatitis of auricle.” Within each code, a fifth digit specifies severity, from 0 (mild) to 4 (severe). Properly coding severity helps determine appropriate treatment approaches.

Keep Records Up to Date

A patient’s atopic dermatitis condition can change over time. It is important to regularly re-evaluate the patient and update ICD-10 codes as needed to reflect the current severity and specifics of the condition. For example, if a patient’s mild atopic dermatitis (L20.0) progresses to being diffuse (L20.8) and severe (L20.84), the code must be updated. Up-to-date coding ensures the patient receives the necessary treatment and care.

In summary, accurately and specifically coding a diagnosis of atopic dermatitis using ICD-10 codes is vital for patient health and well-being, as well as for proper billing and reimbursement. Keeping codes current with the patient’s condition helps enable the best care and treatment approaches. Precise ICD-10 coding for atopic dermatitis should be a high priority.

Common ICD-10 Codes for Atopic Dermatitis

When diagnosing and coding for atopic dermatitis, the most commonly used ICD-10 codes are within the L20 dermatitis category. The specific code used depends on the severity and location of the condition.

L20.0 – Besnier’s prurigo

  • This code is applicable for a severe, unresponsive and exoriated atopic dermatitis with the presence of lichenification. This often appears as eczematous rashes on the neck, wrists, ankles, and other flexural areas.

L20.8 – Other atopic dermatitis.

  • This code is adequate in cofess the atopic dermatitis is not done adultlisted as infantile or Besnier prurigo. It can be applied for cases affecting different parts of the body mildly.

L20.82 Flexural dermatitis of alter atopic type.

  • With the name itself containing the word focal, this code is utilized when the atopic dermatitis is focally present in the flexural areas, such as the folds of elbows and knees. As the human body tends to have these areas, the rash there usually looks as if it were a scale, crust or even redness.

L20.9 – unspecified atopic dermatitis

  • Atopic dermatitis location, type or severity are not considered the vast majority of pixels this code is used. It may be used as a primary code until further details of the condition are acquired.

Some of the related terms used in atopic dermatitis are eczema, neurodermatitis, prurigo of Besnier and allergic contact dermatitis. HIC-10 coding is accurate based on a systematic collection of a patient’s history followed by a physical plasm to determine the category and code applications to a condition with reasons for being identified by its attributes of severity. The specification of correct coding and documentation is quite critical for accurate patient care to the accurate analyzing data of provided health care.

Tips for Selecting the Right ICD-10 Code

When coding for atopic dermatitis (eczema) diagnosis, there are several factors to consider to ensure accurate ICD-10 coding.

Identify the Specific Type and Severity

The ICD-10 code you select should correspond to the particular type of atopic dermatitis the patient is experiencing, such as flexural eczema (L20.82) or hand eczema (L20.81), as well as the severity, ranging from mild (L20.81) to severe (L20.83). Carefully review the patient’s medical record to determine the appropriate type and severity level based on the provider’s documentation.

Check for any Complications or Comorbid Conditions

Be on the lookout for any complications from atopic dermatitis that require additional coding, such as prurigo (L28.0), impetigo (L01.03), or cellulitis (L03.311). Also note any comorbid conditions like asthma (J45.901) or allergic rhinitis (J30.1) which commonly co-occur with atopic dermatitis. Include codes for these related diagnoses to provide a full clinical picture.

Consult the ICD-10 Guidelines

The ICD-10 Official Guidelines for Coding and Reporting provide specific guidelines for atopic dermatitis outlining appropriate code selection that is direction for selection of codes based on parameters that include information on age, outbreak patterns, and distribution. Getting the accompanying cues ought to go about as a safeguard that permits you to figure out which of the patient codes would be most suitable, and precise. For instance, the instructions state that if severe and less severe forms of atopic dermatitis occur, L20.83 coding of the maximum level of severity should be provided.

Ask for Clarification if Needed

If after a review of the medical record it is not clear the best ICD-10 code, do not be afraid to ask the provider to clear up this issue. Spontaneously, it is always advisable to ask for clarification from the primary source rather than making assumptions that may not be true and as a result lead to the wrong coding. 

It is therefore crucial to encode patients’ characteristics and the overall process of care that is rendered unto them for proper patient care and undergo the rightful claims and reimbursement.
Since these steps will not cloud the way of reaching the best ICD-10 codes for permanent identification of atopic dermatitis, it will preserve the compliance to the coding criteria. If you have further questions, please contact me.


What is the ICD-10 code for atopic dermatitis?

The ICD-10 code for atopic dermatitis is L20. This code should be used for initial encounters and for ongoing treatment and management of the condition.

Are there additional codes for the severity or stage of atopic dermatitis?

Yes, there are additional ICD-10 codes to specify the severity of atopic dermatitis:

L20.0 – Besnier’s prurigo: A severe form of atopic dermatitis with pruritic papules and nodules. L20.8 – Other atopic dermatitis: Used for other specified types of atopic dermatitis not classified elsewhere. L20.9 – Atopic dermatitis, unspecified: Used when the severity of the atopic dermatitis is not specified.

What other related conditions share the same ICD-10 code?

Conditions that share the ICD-10 code L20 include:

  • Allergic contact dermatitis of eyelids
  • Endogenous eczema
  • Flexural eczema
  • Intrinsic allergic eczema
  • Prurigo of Besnier

Can the stage or severity change over multiple encounters?

Yes, the stage or severity of atopic dermatitis can change over time and with treatment. It is appropriate for medical coders and physicians to update the ICD-10 code to reflect the current severity and stage of the condition at each patient encounter. Proper coding helps to track the progression and management of the atopic dermatitis.

Accurately coding atopic dermatitis using the ICD-10 system is important for medical billing, tracking prevalence and outcomes, and developing effective treatment plans. Please consult an official ICD-10 coding manual for complete details and updates.

What is the ICD-10 DX code for atopic dermatitis?

Atopic dermatitis, also known as eczema, is a common chronic inflammatory skin disease. To properly code for atopic dermatitis diagnosis, physicians and medical coders should use the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code L20. This code specifically represents atopic dermatitis in the section for “Dermatitis and eczema.”

ICD-10 code L20

The ICD-10 CM code L20 covers the following conditions:

  • Atopic dermatitis
  • Besnier’s prurigo
  • Flexural eczema
  • Infantile eczema
  • Intrinsic (allergic) eczema
  • Prurigo of Besnier

This code should be used for initial encounters, follow up visits, and to report exacerbations or flare ups of the condition. For accurate coding, the provider should document the specific diagnosis in the medical record, including any applicable specifiers to denote disease severity.

To code atopic dermatitis properly, physicians and coders should be familiar with the location and morphology of the condition. Common areas affected include flexural surfaces such as the elbows, behind the knees, face, and neck. Morphology may include erythema, edema, oozing, crusting, scaling, lichenification, and pruritus. Severity can range from mild to severe based on body surface area involved and other measures.

Other Considerations

In some cases, additional codes may be needed to fully describe the patient’s condition. For example, if there is an associated infection present, the correct code for that infection should also be assigned. Codes may also be needed for any procedures performed, such as biopsy, debridement or medication administration.

Accurate ICD-10 coding is important for proper reimbursement, tracking health conditions and identifying patient populations. Careful review of the medical documentation and following official coding guidelines will help ensure correct coding for atopic dermatitis diagnosis and management.

What is the ICD-10 code for L30 9?

Atopic dermatitis, also known as eczema, is a common skin condition that causes an itchy, red rash. It is classified in the ICD-10 coding system under code L30.9, which represents “other dermatitis not elsewhere classified.” This code should be used when a more specific diagnosis is not possible or not provided.

Some other ICD-10 codes related to atopic dermatitis and eczema include:

  • L20 – Atopic dermatitis: A chronic, relapsing dermatitis usually starting in infancy or early childhood with a tendency to recur and persist into adulthood. It is often associated with asthma or hay fever. Use this code for atopic dermatitis without mention of exacerbation.
  • L20.9 – Atopic dermatitis, unspecified: Use this code when atopic dermatitis is documented but the severity is not specified.
  • L20.8 – Other atopic dermatitis: Use this code for other specified types of atopic dermatitis such as infantile, childhood, and adult atopic dermatitis.
  • L21.0-L21.9 – Seborrheic dermatitis: A chronic inflammatory skin disease characterized by erythematous macules and patches with greasy scales. Use codes in this range based on location of the seborrheic dermatitis.

To properly code for atopic dermatitis, physicians and medical coders should determine the specific diagnosis and severity to select the most accurate ICD-10 code. Proper coding helps provide an accurate record of a patient’s condition and appropriate treatment. Accurate coding also helps with billing, quality measures, and longitudinal analysis of disease trends.

In summary, L30.9 is a general code for atopic dermatitis and other types of dermatitis when a more specific diagnosis cannot be made. More precise ICD-10 codes in the L20-L21 range should be used when possible based on the diagnosis and severity documented in the medical record. Accurately coding atopic dermatitis and other skin conditions is important for patient care and administrative purposes.

What is atopic dermatitis diagnosis?

Atopic dermatitis, also known as eczema, is an inflammatory skin condition characterized by patches of chronically itchy, dry, thickened skin, and rashes. To receive an accurate diagnosis of atopic dermatitis, a dermatologist will evaluate your medical history and symptoms. They will examine your skin for the characteristic signs of the condition, including:

  • Dry, scaly, and itchy skin patches
  • Rashes, typically on the face, inside the elbows, behind the knees, and on the hands and feet
  • Thickened, cracked, and crusted skin
  • Raw, sensitive skin from scratching

The dermatologist may also do allergy tests to determine if environmental allergies are triggering or exacerbating your symptoms. Common allergens for people with atopic dermatitis include dust mites, pet dander, pollens, and certain foods.

To confirm the diagnosis, the dermatologist will consider the following criteria:

  1. Onset of symptoms before age 2. Atopic dermatitis most often begins in infancy or early childhood.
  2. Chronic or relapsing dermatitis. The rashes and skin inflammation tend to flare up and then subside, often coming and going for weeks or months at a time.
  3. Personal or family history of atopic diseases like asthma, allergic rhinitis, or food allergies. Atopic dermatitis is linked to a genetic tendency toward allergic conditions.
  4. Distinctive features of atopic dermatitis like lichenification or eczematous lesions. The dermatologist will examine the appearance and distribution of your rashes.
  5. Pruritus or itchiness. The intense itching and scratching of atopic dermatitis skin lesions is a hallmark symptom.

An accurate diagnosis of atopic dermatitis is important to develop an effective treatment plan to manage symptoms and improve quality of life. With proper diagnosis and care, most people with atopic dermatitis can keep flare-ups under control and prevent long-term skin damage.

What is the ICD-10 DX code for atopic dermatitis?

Atopic dermatitis, also known as eczema, is a common skin condition. According to the ICD-10 CM coding guidelines, the diagnosis code for atopic dermatitis is L20. This code should be used for all encounters related to the diagnosis and treatment of atopic dermatitis.

L20 falls under the category of “Dermatitis and eczema” in the ICD-10 CM alphabetical index. This code specifically represents “atopic dermatitis,” which is a chronic inflammatory skin disease with symptoms such as itching, redness, swelling, cracking, weeping, crusting, and scaling of the skin.

Manifestations of Atopic Dermatitis

Common signs and symptoms of atopic dermatitis include:

  • Dry, itchy, scaly skin
  • Redness or swelling
  • Rash on the face, inside the elbows, behind the knees, and on the hands and feet
  • Raw, sensitive skin from scratching
  • Darkened skin patches
  • Rough, leathery skin

Diagnosing Atopic Dermatitis

To diagnose atopic dermatitis, physicians will evaluate the patient’s medical history and symptoms and conduct a physical exam. Diagnostic tests may include:

  • Allergy testing: To determine if allergies are triggering or worsening symptoms. Common allergens for atopic dermatitis include dust mites, pet dander, and certain foods.
  • Skin prick test: To detect allergic reactions to potential allergens. Small amounts of suspected allergens are placed on the skin, which is then pricked to allow the allergens to enter.
  • Patch testing: Adhesive patches containing potential allergens are placed on the skin. The skin is evaluated for reactions after 48-72 hours.
  • Skin biopsy: Rarely needed but can determine if symptoms are due to another skin condition. A small sample of skin is removed for analysis.

With proper diagnosis and treatment, the symptoms of atopic dermatitis can typically be managed well. However, there is currently no cure for this chronic condition. Patients will require ongoing monitoring and care.
