Quick Explanation
This denial occurs when CPT codes representing the destruction of lesions (such as 17000-17111) are billed in violation of AMA coding guidelines or National Correct Coding Initiative (NCCI) edits. It typically indicates that the destruction code was reported alongside an incompatible procedure, such as an excision on the same lesion, or that the documented method of removal does not match the definition of destruction.
Common Causes for D15
Denials with code D15 typically happen for the following specific reasons:
- Reporting both an excision code (CPT 11400-11646) and a destruction code (CPT 17000-17111) for the same lesion on the same date of service.
- Billing add-on destruction codes (e.g., CPT 17003) without the primary base code (CPT 17000), or reporting incorrect quantities that exceed medically unlikely edits (MUEs).
- Failing to document the specific destruction modality used, such as electrosurgery, cryosurgery, laser, or chemical treatment.
- Using flat-rate destruction codes (e.g., 17110 for 1 to 14 lesions) concurrently with individual lesion destruction codes for the same clinical site.
How to Prevent D15 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Verify through NCCI edits that destruction codes are not being billed for the same anatomical lesion as an excision, biopsy, or shaving performed during the same session.
- Ensure the clinical documentation explicitly records the exact number, anatomical locations, and the specific destruction method (e.g., cryotherapy) for all treated lesions.
- Implement automated billing system rules to validate that add-on destruction codes are always appended to the correct primary base code.
- Educate providers and coders on the distinction between destruction (which completely destroys the tissue) and other removal techniques like excision or shaving.

Denial Code: D15 - Destruction codes used inappropriately
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code D15: "Destruction codes used inappropriately".
We are writing to formally appeal the denial of the destruction code(s) billed for the date of service [Date of Service]. According to the AMA CPT guidelines and CMS National Correct Coding Initiative (NCCI) policy, destruction defines the ablation of benign, premalignant, or malignant tissues by any method. The attached medical record clearly documents that [Number] distinct lesion(s) at [Anatomical Location] were independently treated using [Method, e.g., cryosurgery], which is medically necessary and separate from any other procedures performed. Because the documentation supports the precise location, quantity, and destruction modality, this service fully meets the criteria for CPT [Insert Code] and should be reimbursed in full.
Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].
We respectfully request that you reprocess this claim for payment.
Sincerely,
[Your Name]
