Skin tags, also known as acrochordons, are common benign skin growths. When coding for skin tags in medical billing, it’s crucial to use the correct ICD-10 code to ensure proper reimbursement and avoid claim denials. This guide provides a detailed overview of the skin tag ICD 10 codes, differentiating between billable and non-billable codes for accurate medical documentation.
Understanding Skin Tags and Their Medical Coding
Skin tags are small, soft, flesh-colored or slightly darker growths that commonly appear in areas where the skin folds, such as the neck, underarms, groin, and eyelids. While they are harmless, many patients opt for removal due to cosmetic concerns or irritation caused by friction.
In medical coding, the ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) provides specific codes for diagnosing and billing skin tags. Proper coding is essential for insurance claims, medical records, and reimbursement procedures.
Primary Skin Tag ICD-10 Code
The primary ICD-10 code for skin tags is:
L91.8 – Other hypertrophic disorders of the skin
This is the standard code used for documenting skin tags. However, it’s essential to check whether the code is billable or non-billable based on payer guidelines.
Billable vs. Non-Billable Skin Tag ICD-10 Codes
Billable ICD-10 Code for Skin Tags
A billable code is a detailed diagnosis code used for insurance claims. For skin tags, the billable ICD-10 code is:
- L91.8 – Other hypertrophic disorders of the skin
- This code covers various skin conditions, including skin tags, and can be used for reimbursement purposes.
Non-Billable ICD-10 Code for Skin Tags
A non-billable code refers to a general code that requires more specificity. If a non-billable code is used, claims may be rejected or require further documentation. While there isn’t a specific non-billable code for skin tags, using an unspecified skin disorder code (e.g., L91 without further classification) could result in claim issues.
Medical Billing Considerations for Skin Tags
1. Are Skin Tags Covered by Insurance?
Most insurance companies consider skin tag removal a cosmetic procedure unless there is a medical necessity, such as:
- Pain or bleeding due to irritation
- Infection or inflammation
- Rapid increase in size or number
To justify medical necessity, documentation should include symptoms, history, and relevant findings.
2. CPT Codes for Skin Tag Removal
While ICD-10 codes indicate the diagnosis, CPT codes (Current Procedural Terminology) are used for procedures. Common CPT codes for skin tag removal include:
- 11200 – Removal of up to 15 skin tags
- 11201 – Removal of each additional 10 skin tags
Using the correct ICD-10 and CPT code combination ensures proper billing and claim approval.
Common Mistakes in Skin Tag ICD-10 Coding
- Using non-billable codes – Always verify the specificity of the ICD-10 code before submitting claims.
- Incorrect use of L91.8 – While L91.8 is billable, supporting documentation is necessary to justify the diagnosis.
- Failure to establish medical necessity – If skin tag removal is elective, insurance may not cover the procedure.
Conclusion
Accurate medical coding for skin tags using the appropriate skin tag ICD 10 code (L91.8) is crucial for successful insurance reimbursement. Ensuring proper documentation, understanding billing guidelines, and using the right CPT codes can help healthcare providers avoid claim denials and improve revenue cycle management.
