After segmental dermabrasion, which code should be reported?

Segmental dermabrasion is a specific type of skin resurfacing procedure that involves the mechanical exfoliation of the epidermis and part of the dermis in a localized area. When coding for this procedure, it is essential to use the appropriate code that accurately reflects the treatment provided.

The correct code to report for segmental dermabrasion is 15781. This code is designed specifically for the excision of skin lesions, including dermabrasion, in a specified anatomical site and describes the technique used during the procedure. This is critical for accurate medical coding, insurance billing, and ensuring appropriate reimbursement for the services provided.

The other codes listed pertain to different services or are associated with other types of patient encounters. For example, codes 99215 and 99243 denote office or outpatient visit levels for established patients, which are unrelated to surgical or dermatological procedures like dermabrasion. Code 13121 refers to delayed primary closure of wounds, which again does not match the nature of segmental dermabrasion. Thus, 15781 is the appropriate choice as it correctly identifies the nature of the procedure performed.
