Understanding ICD-10 Codes for Skin Tags (L91.8)

The ICD-10 code L91.8 is essential for accurately documenting and treating skin tags in medical records. This guide dives deep into its applications, related codes, and the clinical significance of proper coding.

What Are Skin Tags?

Skin tags, medically known as acrochordons, are benign, non-cancerous growths of skin that often develop in areas of friction, such as the neck, armpits, and groin. These small, soft, flesh-colored lesions are generally harmless but can cause discomfort or cosmetic concerns.

Causes and Risk Factors:

  • Friction between skin surfaces
  • Obesity and diabetes
  • Hormonal changes (e.g., pregnancy)
  • Genetic predisposition

Billable ICD-10 Codes for Skin Tags

Neck (L91.8)

Skin tags frequently appear on the neck due to constant friction from clothing, jewelry, or skin folds. The ICD-10 code L91.8 classifies these as hypertrophic skin disorders, making treatments such as excision or cryotherapy eligible for insurance reimbursement. This coding is essential for documenting procedures, especially when skin tags cause irritation, snagging, or cosmetic concerns.

Irritated Skin Tags (L91.8)

Skin tags can become irritated due to friction, pressure, or trauma, leading to redness, discomfort, or bleeding. These cases fall under L91.8, “Other hypertrophic disorders of the skin.” This code allows healthcare providers to document and bill for treatments like removal or topical care aimed at alleviating irritation.

Inflamed Skin Tags (L98.8)

When skin tags become inflamed due to infection or repeated trauma, they are coded under L98.8, categorized as “Other specified disorders of the skin.” This classification ensures that treatments, including antibiotics or surgical removal, are billable. Proper documentation is crucial in these cases, as inflamed tags may mimic other skin conditions.

Eyelid (D23.9)

Skin tags that develop on the eyelids are often removed for both medical and cosmetic reasons. The ICD-10 code D23.9, which pertains to benign neoplasms of the skin, applies here. Removal might be necessary if the tags obstruct vision or cause discomfort during blinking, and this code ensures the procedure is billable.

Face (D23.9)

Facial skin tags can be aesthetically displeasing and are classified under D23.9, covering benign neoplasms of the skin. While generally harmless, these tags might require removal for medical or cosmetic purposes, such as preventing irritation during shaving or skincare routines. This code enables billing for their treatment.

Left Axilla (L91.8)

The left axilla, or armpit, is a common location for skin tags due to constant friction and moisture. These are classified under L91.8, allowing for billing when removal is necessary to address discomfort, odor issues, or hygiene challenges. Treatment options include cryotherapy, excision, or electrosurgery.

Bleeding Skin Tags (L98.8)

Skin tags that bleed, often caused by irritation or accidental trauma, are coded under L98.8 as “Other specified disorders of the skin.” These cases often require prompt attention to prevent infection. Treatments such as cauterization or excision are billable under this code, ensuring patients receive necessary care.

Rectal (K64.4)

Residual hemorrhoidal skin tags, common in the rectal area, are documented under the code K64.4. These tags can cause hygiene difficulties or discomfort during bowel movements. Removal is typically performed via outpatient procedures and is fully billable when documented correctly.

Genital (L98.8)

Skin tags in the genital area can cause significant discomfort or embarrassment for patients. These are classified under L98.8, covering “Other specified disorders of the skin.” Removal procedures are often billable, ensuring access to treatments like surgical excision or laser therapy.

Labial (L98.8)

Skin tags on the labia are categorized under L98.8 and may require removal for both medical and aesthetic reasons. These growths can interfere with personal hygiene or cause discomfort during physical activities, making their treatment billable under this code.

Groin (L91.8)

Skin tags in the groin area are a common issue, particularly in individuals who experience frequent chafing or have underlying conditions like obesity. These tags are coded as L91.8, ensuring reimbursement for their removal when they cause irritation or secondary infections.

Back (D23.9)

The back is a common site for skin tags, especially in areas prone to friction from clothing or straps. These tags are coded under D23.9, covering benign neoplasms of the skin. Removal is billable when performed for medical or cosmetic reasons, ensuring proper documentation.

Perianal (K64.4)

Skin tags around the perianal region are typically linked to hemorrhoidal issues and are coded under K64.4. These tags can be problematic for hygiene and comfort, particularly after bowel movements. Their removal is billable when required to improve quality of life or resolve medical concerns.

Ear (D23.9)

Skin tags on the ear are uncommon but are classified under D23.9 as benign neoplasms. They can be removed for cosmetic or functional reasons, such as interference with wearing earrings or glasses, and the procedure is billable under this code.

Anus (K64.4)

Anus skin tags are similar to perianal tags and are often associated with residual hemorrhoidal conditions. These are coded under K64.4 and are billable when removal is necessary for hygiene or comfort, especially in cases of irritation or bleeding.

Non-Billable ICD-10 Codes for Skin Tags

Miliaria Rubra (L72.3)

Miliaria rubra, or heat rash, is often mistaken for skin tags due to its appearance. However, this condition is entirely different and is classified under L72.3. Since it is not a skin tag, it is non-billable for treatments related to skin tags.

Hypertrophic Scar (L91.0)

Hypertrophic scars, raised areas of skin resulting from injury or surgery, are coded as L91.0. Although they may resemble skin tags, they are a separate condition and not billable under skin tag-related ICD-10 codes.

Epidermal Cyst (L72.0)

Epidermal cysts, which are small lumps beneath the skin, are distinct from skin tags and classified under L72.0. These cysts require different treatment approaches and are non-billable under skin tag codes.

Unspecified Skin Tags (D23.9)

Unspecified skin tags are coded under D23.9, but when their location or condition isn’t clearly documented, they may not be billable. Proper documentation is critical to ensure accurate coding and eligibility for reimbursement.
