For medical billers, coders, and providers, selecting the correct ICD-10 code for skin tags is essential for reimbursement, compliance, and avoiding denials.As payer scrutiny around dermatology procedures continues to increase, accurate diagnosis coding has become even more important.
Many payers now require stronger documentation supporting medical necessity before approving skin tag removal claims. Using the correct skin tag ICD 10 code, along with detailed clinical documentation, can help practices reduce denials, support compliance, and improve reimbursement outcomes.
This guide breaks down the skin tag ICD 10 code most payers expect, when to use each related code, how they align with CPT procedure codes, and documentation practices that keep claims clean.

What Are Skin Tags?
Skin tags (acrochordons) are small, soft, benign growths of skin that typically appear on the neck, eyelids, armpits, groin, or under the breasts. They are usually painless but can cause discomfort if irritated by clothing, jewelry, or friction. They’re most common in adults over 45 and occur more frequently in people who are overweight or have type 2 diabetes, though they can appear in anyone regardless of age or health status.
Cosmetic vs Medically Necessary:
- Cosmetic: Removal for appearance only, not covered by most payers.
- Medically necessary: Removal required due to symptoms such as bleeding, irritation, recurrent inflammation, or interference with daily activities, billable with correct coding and documentation.
Primary ICD-10 Code for Skin Tags
L91.8 – Other hypertrophic disorders of the skin
This is the ICD 10 code for skin tags most widely accepted by Medicare and commercial payers, and it remains current and billable in the FY2026 ICD-10-CM code set. It’s classified under hypertrophic disorders of the skin and applies whenever removal is medically justified rather than purely cosmetic.
The ICD-10-CM code L91.8 is the primary diagnosis code used for documenting skin tags (acrochordons). It is classified under hypertrophic disorders of the skin and is widely accepted by Medicare and commercial payers when removal is medically necessary.
| Field | Detail |
|---|---|
| Code | L91.8 |
| Description | Other hypertrophic disorders of the skin |
| Billable | Yes |
| Typical use | Skin tags with documented symptoms justifying removal |
| Payer note | Always verify payer-specific medical necessity policy |
Skin tags are generally harmless, but when they cause irritation, bleeding, recurrent inflammation, pruritus, or obstruction of movement or vision, L91.8 supports medical necessity for removal.
Correct use of L91.8 requires careful documentation. Providers should specify the number of lesions, their location (neck, eyelid, groin, armpit, perianal), and the symptoms justifying removal. For example, documenting that “skin tags on the eyelid cause irritation and blurred vision” helps establish medical necessity. When tags are removed, coders typically pair L91.8 with CPT 11200 (up to 15 lesions) or 11201 (each additional 10 lesions).
Billable vs Non-Billable Skin Tag Coding
Payer review continues to focus on whether the claim is medically necessary or purely cosmetic. That makes it important to separate billable skin tag coding from non-billable cosmetic removal.
- Billable when medically necessary: L91.8 when the skin tag causes irritation, bleeding, friction, inflammation, or functional problems.
- Non-billable or self-pay when cosmetic: Z41.1 may apply when the removal is purely cosmetic.
- Key point: Cosmetic-only removal is usually not covered by insurance, and the patient should be informed of financial responsibility before the procedure if required by policy.
This distinction matters because some denials happen not because the code is wrong, but because the service was never covered under medical necessity in the first place.
Additional ICD-10 Codes by Location and Type
While L91.8 is the primary diagnosis code, other ICD-10 codes may apply depending on the patient’s condition, skin tag location, or associated symptoms.These variations are especially relevant in dermatology coding where documentation often must capture not just the presence of lesions but their type, location, and associated symptoms.
| Code | Description | When to use |
|---|---|---|
| L91.8 | Other hypertrophic disorders of the skin | Default code for neck, armpit, groin, and most general-site skin tags |
| K64.4 | Residual hemorrhoidal skin tags | Perianal or hemorrhoidal-origin skin tags never default to L91.8 here |
| H02.9 | Unspecified disorder of eyelid | Eyelid skin tags, when documentation supports a functional or visual issue |
| D23.9 | Benign neoplasm of skin, unspecified | Large or atypical tags, or when pathology/provider notes specify “neoplasm” |
| L98.8 | Other specified disorders of the skin and subcutaneous tissue | Secondary option for lesions not clearly classified elsewhere; use sparingly |
| Q82.8 | Other specified congenital malformations of skin | Congenital skin tags present from birth, rather than acquired later in life |
Location-Specific Considerations
Skin tags can appear in different body areas, and location often determines coding specificity:
- Neck/Armpits/Groin – L91.8 (default unless otherwise specified)
- Eyelid – H02.9 or L91.8 (with documentation supporting functional issue)
- Perianal/hemorrhoidal region – K64.4
- Other skin sites – D23.9 or L98.8 (when documented as neoplasm or unspecified disorder)
The location alone is not enough to prove medical necessity. The provider should document why the lesion is being removed and how it affects the patient. For eyelid lesions, note irritation, visual obstruction, or repeated trauma. For perianal lesions, document that the finding is consistent with a residual hemorrhoidal skin tag rather than a general skin lesion.
Common Coding Errors with Skin Tags
- Using L91.8 for purely cosmetic removals – Results in denials since cosmetic procedures are not covered.
- Failing to pair ICD-10 with CPT – Billing removal without matching diagnosis code leads to claim rejections.
- Omitting documentation of medical necessity – Even the correct ICD-10 code won’t be reimbursed if symptoms aren’t supported in notes.
- Confusing hemorrhoidal skin tags with general skin tags – K64.4 must be used for perianal tags.
- Using an unsupported location-based diagnosis without chart justification.
- Missing the lesion count or procedure method in the operative note.
Accurate coding for skin tags requires more than just entering L91.8. Payers look for specific diagnosis codes tied to the location, supporting documentation that proves medical necessity, and correct CPT code pairing for removal.
By following best practices, coders and providers can prevent denials, ensure compliance, and capture rightful reimbursement for medically necessary procedures.

Talk to Our Dermatology ExpertCPT Codes for Skin Tag Removal
Diagnosis coding must be paired correctly with procedure codes when removal is performed. The most common CPT codes for skin tag removal include:
CPT 11200 – Removal of Skin Tags, Up to and Including 15 Lesions
This CPT code is reported when a provider removes up to 15 skin tags during the same encounter. Removal methods may include snip excision, electrocautery, cryotherapy, or similar techniques. Documentation should clearly identify the total number of lesions removed, their location, the treatment method used, and the medical necessity supporting removal.
CPT 11201 – Each Additional 10 Lesions
CPT 11201 is an add-on code used in conjunction with CPT 11200 when more than 15 skin tags are removed during the same session. Providers should document the total lesion count and treatment details to support reimbursement and reduce the likelihood of payer audits or claim denials.
Coding tip: Documentation supporting the CPT codes must include:
- Number of tags removed.
- Method of removal (snip excision, cryotherapy, cautery, etc.).
- Medical necessity (e.g., irritation, bleeding, recurrent infection).
Medical Necessity Requirements for Skin Tag Removal
Correct diagnosis coding alone does not guarantee reimbursement. Most payers require documentation demonstrating that skin tag removal is medically necessary rather than cosmetic.
Commonly Covered Situations
- Recurrent irritation from clothing or jewelry
- Bleeding or recurrent trauma
- Infection or inflammation
- Functional impairment
- Obstruction of vision (eyelid lesions)
- Persistent discomfort affecting daily activities
Commonly Non-Covered Situations
- Cosmetic concerns only
- Appearance-related removal requests
- Patient preference without documented symptoms
As payer reviews continue to increase, documenting the symptoms that support medical necessity is often the determining factor between claim approval and denial.
Documentation Best Practices
To avoid denials, providers should document the following details:
- Medical necessity: Indicate irritation, bleeding, infection, or obstruction.
- Location: Specify where on the body the skin tags are located.
- Quantity: Document the number of lesions removed.
- Method: Record how they were removed.
- Patient symptoms: Note discomfort, interference with daily activities, or repeated infections.
Good documentation should also distinguish between cosmetic and medically necessary care. If the note says the patient requested removal only for appearance, the claim should not be billed as a covered procedure.

No. Skin tag removal is typically covered only when medically necessary, for example, irritation, bleeding, or infection. Cosmetic removals are usually not billable and are billed directly to the patient.
L91.8 is the standard, most widely used skin tag icd 10 code. Other codes such as K64.4, H02.9, and D23.9 apply only when the location or pathology calls for more specificity.
Medicare generally treats skin tag removal as cosmetic unless documentation shows medical necessity, such as bleeding, pain, or recurrent irritation. Without that documentation, Medicare typically denies the claim.
The same code, L91.8, applies regardless of how many tags are removed. The lesion count affects the CPT code (11200 plus 11201 as needed), not the diagnosis code.
Often yes, since bleeding is one of the clearest indicators of medical necessity. The provider’s note needs to document the bleeding explicitly for the claim to be supported.
Check whether the claim lacked medical necessity documentation, used an incorrect place of service, or billed a cosmetic removal as medically necessary. Correcting the documentation and resubmitting with the proper ICD-10 code often resolves the denial.
