Billing and Coding: Wound Care

Claims must be submitted with an ICD-10-CM code that represents the reason the procedure was done. The ICD-10-CM code must be billed to the highest level of specificity for that code set. The ICD-10-CM code must be linked to the appropriate procedure code. A therapist acting within their scope of practice and licensure performing active wound care management services must add the appropriate therapy modifier to the CPT code billed. In addition the therapy Revenue Code must be submitted for that service. If a non-therapist performs the service, no therapy modifiers are used and a non-therapy Revenue Code must be submitted for the service. Please see MM10176 for more information. The wound depth debrided determines the appropriate code. Use appropriate modifiers when more than one wound is debrided on the same day. When providing and billing surgical debridement, the surgical debridement service is to include: the pre-debridement wound assessment, the debridement, and the post-procedure instructions provided to the patient on the date of the service. When a “reasonable and necessary” E/M service is provided and documented on the same day as a debridement service, it is payable by Medicare when the documentation clearly establishes the service as a “separately identifiable service” that was reasonable and necessary, as well as distinct, from the debridement service(s) provided. Only when there is a separately identifiable service being treated by the therapist, and the documentation supports this treatment, would the service be considered for payment utilizing modifier 59 or a more specific modifier as appropriate (e.g., LT, RT, XS, etc). It is the provider’s responsibility to select codes carried out to the highest level of specificity and selected from the ICD-10-CM code book appropriate to the year in which the service is rendered for the claim(s) submitted. No procedure code to diagnosis code limitations are being established at this time.
