Skin tags may be small and harmless, but when it comes to medical billing , they can cause surprisingly big headaches. Most providers are aware of the prevalence of skin tags—patients request removals every day in primary care and dermatology settings—but not every removal is billable. Payers want to know whether the procedure was medically necessary or purely cosmetic before they approve payment.
And here’s the tricky part: there’s essentially one primary ICD-10 code for skin tags—but you have to use it correctly, and pair it with the right CPT/HCPCS code and documentation, or the claim won’t stand up under review.
This guide breaks down everything providers need to know about ICD-10 coding for skin tags, from diagnosis codes to payer rules to billing workflow.
Skin tags , or acrochordons, are small, benign growths of skin that often appear in skin folds—neck, eyelids, armpits, groin, and under the breasts. They’re not dangerous, but they can become irritated, bleed, or cause discomfort when rubbed by clothing or jewelry.
Key point for billing: Removal is typically considered cosmetic unless the tag is bleeding, irritated, inflamed, or obstructing function (like eyelid tags affecting vision).
When it comes to billing for skin tags, providers often assume that a single code will suffice. In reality, payers want more context. Was the removal purely cosmetic? Was the skin tag bleeding, painful, or irritated? Did the patient have an underlying condition, such as diabetes, that contributed to its development?
The ICD-10 system enables you to capture that story in a coded form. Using the right combination of codes not only supports medical necessity but also helps reduce denials, especially since most insurers are quick to label skin tag removal as a cosmetic procedure.
The primary ICD-10 code for skin tags is L91.8 – Other hypertrophic disorders of skin.
Provider Tip: Always start with L91.8 as the base diagnosis for skin tag removal claims.
Sometimes, a skin tag causes or is associated with symptoms that warrant medical attention. Adding these codes alongside L91.8 strengthens your claim.
If the patient has diabetes, you document a connection between skin tags and the condition.
Example: A diabetic patient presents with multiple inflamed tags in the neck area. Coding both L91.8 and E11.9 provides a stronger justification than coding L91.8 alone.
Encounter codes are not always required, but they can be helpful in claims processing—especially when removals are cosmetic.
Tip: These codes often come into play when you need to differentiate between covered and non-covered services during an audit.
| Category | ICD-10 Code | Description / Use Case |
|---|---|---|
| Primary Diagnosis | L91.8 | Other hypertrophic disorders of skin include skin tags (acrochordon). Always the main code for skin tag cases. |
| Associated Conditions | R23.8 | Other specified skin changes – use if the tag is bleeding, inflamed, or irritated. |
| L29.9 | Pruritus, unspecified – use if itching is the primary complaint. | |
| E11.9 | Type 2 diabetes mellitus without complications – use if skin tags are linked to diabetes. | |
| Encounter Codes | Z41.1 | Encounter for cosmetic surgery – when removal is elective and self-pay. |
| Z71.89 | Other specified counseling – when the patient is counseled about skin tags without removal. |
Always code L91.8 for skin tags, then add supporting symptom or condition codes when applicable. This creates a stronger case for medical necessity and helps defend against denials, especially when insurers default to labeling skin tag removal as cosmetic in nature.
Just like wound care, skin tag billing isn’t only about the diagnosis code; it’s about the whole workflow.
Tip: Inform patients upfront that cosmetic removals are usually self-pay. Many practices set a flat fee for cosmetic skin tag removal.
Payers demand detailed notes showing why removal was medically necessary. Your documentation should include:
Example of strong documentation:
The patient presents with multiple skin tags on the right side of the neck. One tag measuring 0.7 cm is inflamed and bleeds when rubbed by the shirt collar. Snip excision performed under local anesthesia. Removal is medically necessary due to recurrent bleeding and irritation.
ICD-10 informs the payer of the condition. CPT tells them what you did about it.
Common CPT Codes:
Key Rules:
HCPCS Code (Medicare use):
G0247 – Routine foot care (sometimes used in diabetic patients, if associated with other covered foot care services)
Attach medical notes, wound photos (if allowed), and explain the risk of infection/bleeding to prove the necessity.
One of the biggest frustrations providers face with skin tag removal is that coverage rules vary wildly by payer. What Medicare considers a “covered service,” Medicaid may treat differently, and commercial insurers often dismiss it as cosmetic.
That’s why understanding payer-specific policies upfront can save you from denials, wasted staff time, and awkward financial conversations with patients.
Let’s break down how the three big payer groups look at skin tag removal:
Coverage is extremely limited. Medicare doesn’t cover skin tag removal if it’s purely cosmetic.
They will only pay if the skin tag is symptomatic:
Documentation is everything. If you don’t explicitly document the symptom, expect a denial. Medicare auditors look for keywords such as “bleeding,” “infected,” “irritated, ” or “obstructive.”
Example: “Patient presents with multiple acrochordons, one located on the right upper eyelid, causing irritation and obstruction of vision.”
This statement supports coverage better than just “skin tag removal”.
Tip: Always check your state’s Local Coverage Determination (LCD) or policy manual for the most up-to-date information. For example, some states cover removal if skin tags are associated with diabetes complications, while others deny coverage unless there is an active infection.
Most commercial payers exclude cosmetic procedures outright, and skin tag removal typically falls into this category.
The only chance of coverage is when you can demonstrate medical necessity—similar to Medicare (e.g., bleeding, infection, or obstruction).
Clear documentation and the correct use of modifiers can help:
Even with strong documentation, many commercial payers will still deny claims unless the removal meets strict criteria.
Best practice: Have patients sign an Advance Beneficiary Notice (ABN)-style waiver (or the commercial equivalent) acknowledging that they may be responsible for charges if the payer denies coverage. This avoids patient disputes later.
Skin tag removals may be simple in the clinic, but the billing side is far from simple. The ICD-10 code L91.8 is your go-to diagnosis code, but payers will deny claims unless you clearly document medical necessity. The key is to pair the diagnosis with CPT 11200/11201, support it with symptoms, and be transparent with patients about coverage.
Create a skin tag removal template in your EHR that prompts for:
This ensures every note supports billing and avoids “cosmetic” denials.
Most payers treat skin tag removal as cosmetic—but with the right skin tag coding and medical necessity documentation, you can protect your revenue.
