What is CPT Code 11101

CPT code 11101 is used to indicate an additional biopsy of the skin. This code is an add-on, meaning it is used in conjunction with another primary biopsy code (such as 11100) when multiple biopsies are performed during the same session. It helps healthcare providers accurately document and bill for the extra work involved in taking more than one skin sample for diagnostic purposes.

Does CPT 11101 Need a Modifier?

For CPT code 11101, which is an add-on code for skin biopsy, the following modifiers may be applicable:

1. Modifier 25: Significant, separately identifiable evaluation and management (E/M) service by the same physician or other qualified healthcare professional on the same day of the procedure or other service. Use this modifier if an E/M service was provided on the same day as the biopsy and is distinct from the procedure.

2. Modifier 59: Distinct procedural service. This modifier is used to indicate that the biopsy is a distinct service from other procedures performed on the same day. It helps to bypass National Correct Coding Initiative (NCCI) edits that might otherwise bundle the services together.

3. Modifier 76: Repeat procedure or service by the same physician or other qualified healthcare professional. Use this modifier if the biopsy procedure is repeated on the same day by the same provider.

4. Modifier 77: Repeat procedure by another physician or other qualified healthcare professional. This modifier is used if the biopsy procedure is repeated on the same day but by a different provider.

5. Modifier 91: Repeat clinical diagnostic laboratory test. Although less common for biopsies, this modifier might be used if the biopsy is repeated for clinical diagnostic purposes on the same day.

6. Modifier XS: Separate structure. This modifier is used to indicate that the biopsy was performed on a separate organ/structure from other procedures performed on the same day.

7. Modifier XE: Separate encounter. This modifier is used to indicate that the biopsy was performed during a separate encounter from other services provided on the same day.

8. Modifier XP: Separate practitioner. This modifier is used when the biopsy is performed by a different practitioner than other services provided on the same day.

9. Modifier XU: Unusual non-overlapping service. This modifier is used to indicate that the biopsy service does not overlap with other services provided on the same day.

These modifiers help ensure accurate billing and reimbursement by providing additional context about the circumstances under which the biopsy was performed.

CPT Code 11101 Medicare Reimbursement

The CPT code 11101, which is an add-on code, is reimbursed by Medicare. Reimbursement for this code is determined based on the Medicare Physician Fee Schedule (MPFS). The MPFS outlines the payment rates for services provided to Medicare beneficiaries. Additionally, Medicare Administrative Contractors (MACs) play a crucial role in processing claims and ensuring that the reimbursement aligns with the guidelines set forth by the Centers for Medicare & Medicaid Services (CMS). Therefore, if the service associated with CPT code 11101 meets the necessary criteria and is billed correctly, it will be reimbursed by Medicare.
