11103 CPT Code: What You Need to Know
If you’re in dermatology, you know how important it is to bill correctly for every procedure.
That’s where understanding dermatology CPT codes like 11103 comes in.
Whether you’re a dermatologist or managing a clinic, knowing when and how to use this code can help streamline your billing process and get the reimbursements you deserve.
Here’s a simple guide to CPT code 11103, how it works, and how we at The Auctus Group can help make your billing stress-free.
What is CPT Code 11103?
CPT code 11103 is used to report additional skin biopsies during the same session.
It’s an add-on code, meaning it’s billed alongside a primary biopsy code like 11102.
For example, if you take three biopsy specimens, you’ll use 11102 for the first one and 11103 for the second and third.
This code is specific to skin biopsies and makes it easier to account for multiple specimens without submitting separate claims for each one.
When Should You Use CPT Code 11103?
This code is for cases where more than one skin biopsy is performed during the same visit.
Here’s how it works:
- First Biopsy: Use CPT code 11102 for the initial specimen.
- Additional Biopsies: Use CPT code 11103 for every specimen after the first.
Example:
A dermatologist collects four biopsy specimens from a patient.
- 11102 covers the first specimen.
- 11103 is used for the remaining three specimens.
Tips for Correct Use:
- Only use 11103 when there is a primary code like 11102 on the claim.
- Make sure your documentation supports the need for additional biopsies.
- Apply the right modifiers to indicate separate sites or procedures, such as 59 or XS.
CPT Code 11103 Description and Billing Guidelines
The official description for CPT code 11103 is:
“Skin biopsy, each additional lesion, after the first (list separately in addition to code for primary procedure).”
11103 Billing Guidelines:
- Always pair 11103 with a primary code like 11102.
- Document the specific reasons for each biopsy to avoid claim denials.
- Use modifiers when needed to show the biopsies were performed on separate sites.
These steps help ensure your claims are clear and reimbursed without delays.
Common Mistakes to Avoid
Mistakes with CPT code 11103 are common but easy to avoid with the right approach.
Here’s what to watch out for:
- Using 11103 Without a Primary Code: This code must always follow a primary biopsy code.
- Skipping Modifiers: Forgetting to use modifiers like 59 can lead to claim denials.
- Incomplete Documentation: Each biopsy needs clear documentation explaining why it was necessary.
By double-checking these areas, you can prevent billing headaches and keep your practice running smoothly.
Examples of Proper Use for CPT Code 11103
Scenario:
A patient comes in with suspicious lesions on their arm and back.
The dermatologist performs:
- One punch biopsy on the arm.
- Two punch biopsies on the back.
Billing Breakdown:
- 11102: First punch biopsy on the arm.
- 11103 x2: For the additional biopsies on the back.
This approach ensures you’re accurately coding and billing for all biopsies performed.

FAQs
What is CPT code 11103?
CPT code 11103 is an add-on code used to report additional skin biopsy specimens taken during the same session. It is billed alongside a primary biopsy code, such as CPT 11102, and cannot be used independently.
What is the difference between a tangential biopsy and a shave biopsy?
A tangential biopsy involves removing a portion of the epidermis and dermis using a blade without excising the full thickness of the skin. A shave biopsy, on the other hand, removes a lesion by cutting parallel to the skin’s surface, typically including a small portion of the dermis but not the subcutaneous layer.
What is ICD 10 11103?
ICD-10 does not directly correspond to CPT codes like 11103. ICD-10 codes are diagnostic codes that describe the reason for the biopsy, while CPT codes refer to the procedure itself. For a procedure like a biopsy, you would pair CPT code 11103 with an appropriate ICD-10 diagnosis code based on the condition being treated.
What is the difference between shave removal and shave biopsy?
A shave removal is a therapeutic procedure intended to completely remove a lesion, often for cosmetic or medical purposes. A shave biopsy, however, is diagnostic and involves removing a small portion of a lesion to analyze it for pathology.
What is CPT code sclerotherapy?
CPT codes for sclerotherapy, which involves injecting a solution to treat varicose or spider veins, include 36470 for a single vein and 36471 for multiple veins during the same session.
How do I bill my CPT code 11103?
To bill CPT code 11103, it must be included as an add-on code with a primary biopsy code, such as CPT 11102. Each additional lesion biopsy beyond the first should be billed with 11103. Ensure proper documentation and consider using modifiers like 59 or XS if needed.
What CPT code is used for a shave biopsy?

What is the ICD-10 code for tangential biopsy?

What is diagnosis code I35?
ICD-10 code I35 refers to nonrheumatic aortic valve disorders, such as aortic insufficiency or stenosis. It is unrelated to dermatology or biopsy procedures.
