Seborrheic Dermatitis ICD-10-CM Codes

What ICD-10 Codes are Used for Seborrheic Dermatitis?

Seborrheic Dermatitis, a prevalent skin disorder that primarily targets the scalp, is identified by symptoms such as red, scaly skin, dandruff, and discomforting itching. For accurate diagnosis, targeted treatment, and precise medical billing of this condition, certain specific ICD-10 codes are employed:

1. L21.9 - Unspecified Seborrheic Dermatitis: This code is used when the specific subtype of seborrheic dermatitis isn't explicitly mentioned. It offers a broad classification, covering all manifestations not specified elsewhere.

2. L21.8 - Other Seborrheic Dermatitis: This code caters to those conditions that fail to align with other defined seborrheic dermatitis codes. It accommodates unique cases falling outside the typical categorizations.

3. L21.0 - Seborrhoea Capitis: This specific code relates to seborrheic dermatitis that predominantly affects the scalp, often resulting in dandruff or scaly patches.

4. L21.1 - Seborrheic Infantile Dermatitis: As the name suggests, this code is reserved for infant-related cases. It encompasses conditions seen in babies, often called 'cradle cap.'

5. L21.3 - Seborrheic Dermatitis of Eyelids: This code is used when the condition specifically affects the eyelids, causing redness, swelling, and flaking.

6. L21.2 - Sebaceous Cyst: This code refers to small, non-cancerous bumps under the skin caused by blocked sebaceous glands.

Each code helps healthcare providers accurately diagnose, document, and treat seborrheic dermatitis while facilitating precise medical billing.

Clinical Information

Seborrheic Dermatitis, a chronic and recurrent skin condition, is primarily characterized by the following clinical features:

• Redness and Rash: The condition often presents as a rash or redness on the scalp or skin. This is one of the earliest signs and is typically accompanied by itching.

• Scaly, Flaky Skin: Affected individuals frequently experience scaly and flaky skin. These scales can be yellowish or white and are often oily or moist.

• Itching and Inflammation: Itching is a common symptom ranging from mild to severe. The skin in the affected areas may also become inflamed, leading to discomfort.

• Dandruff: One of the key manifestations of seborrheic dermatitis is dandruff. This can appear in the scalp hair, eyebrows, beard, or mustache, presenting as small, white flakes.

• Pink or Red Spots: In some cases, pink or red spots may appear on the skin. These are generally flat and can be seen on the chest, back, or other body parts.

• Greasy or Oily Skin: Seborrheic dermatitis often results in greasy or oily skin, particularly in the T-zone (forehead, nose, and chin) and scalp.

• Stinging or Burning Sensation: Some individuals may experience a stinging or burning sensation in the affected areas, especially when applying certain creams or lotions.

Understanding these clinical features is crucial for accurately diagnosing and effectively managing seborrheic dermatitis.
