Skin tags are common, but coding them correctly can be challenging due to variations in documentation, location, and medical necessity.
This comprehensive guide explains ICD-10 for skin tag, billable vs non-billable codes, documentation requirements, and frequently searched questions to help you avoid denials and improve reimbursement.
What Are Skin Tags?
Skin tags, medically known as acrochordons, are small, soft, benign skin growths that typically appear in areas where skin rubs together such as the neck, underarms, eyelids, and groin. They are generally harmless but may become irritated, inflamed, or bleed due to friction.
From a coding perspective, skin tags are classified under skin and subcutaneous tissue disorders, and the correct ICD-10 code depends on their condition, location, and symptoms.
Skin Tags ICD-10 Code Overview
When searching for icd 10 skin tag or skin tag icd 10, the most commonly used code is:

4. K64.4 – Residual Hemorrhoidal Skin Tags
- Used for anal or perianal skin tags
- Often associated with hemorrhoids
These codes are considered billable when supported by proper clinical documentation and medical necessity.
Non-Billable or Incorrect Codes for Skin Tags

- L91.0 – Hypertrophic scar

These are not appropriate for skin tags and may result in rejected claims if used incorrectly.
ICD-10 Code for Removal of Skin Tags
A common search term is “icd 10 code for removal of skin tags”, but it is important to understand:
- ICD-10 codes describe the diagnosis
- CPT codes describe the procedure
For skin tag removal, the commonly used CPT codes are:
- 11200 – Removal of skin tags up to 15 lesions
- 11201 – Each additional 10 lesions
These must be paired with the correct ICD-10 diagnosis code such as L91.8 to justify medical necessity. ()
Medical Necessity vs Cosmetic Removal
One of the biggest challenges in skin tag coding is determining whether removal is medically necessary.
Medically Necessary (Billable)
- Bleeding skin tags
- Pain or irritation
- Recurrent infection
- Interference with daily activities
Cosmetic (Non-Billable)
- Removal for appearance only
- No symptoms or complications
Insurance companies typically do not cover cosmetic skin tag removal, which is why proper documentation is critical. ()
Documentation Requirements for Accurate Coding
To ensure correct billing and avoid denials, providers must include detailed documentation.
Key Documentation Elements
- Number of skin tags
- Location on the body
- Symptoms such as pain, bleeding, or irritation
- Method of removal
- Medical necessity
Incomplete documentation is one of the leading causes of coding errors and rejected claims. ()
Common Coding Mistakes to Avoid
Even experienced coders can make mistakes when dealing with icd 10 for skin tag. Here are the most common issues:
1. Using L91.8 for Cosmetic Cases
This can lead to immediate claim denial if no medical necessity is documented.
2. Misclassifying Skin Conditions
Confusing cysts, scars, or other lesions with skin tags results in incorrect coding.
3. Missing Supporting Documentation
Lack of symptom documentation can make a billable code non-reimbursable.
4. Not Linking CPT and ICD-10 Codes Properly
Procedure codes must align with diagnosis codes to justify treatment.
How to Choose the Correct ICD-10 Code
Follow these steps to ensure accurate coding:
Step 1: Identify the Condition
Confirm that the lesion is a skin tag and not another skin condition.
Step 2: Check Symptoms
Determine if the tag is symptomatic or cosmetic.
Step 3: Review Location
Some locations require different codes such as D23.9 or K64.4.
Step 4: Ensure Documentation

Step 5: Select the Most Specific Code
Avoid unspecified codes whenever possible.
