^*”Clinic” refers to a hospital-based outpatient wound care department.

^†If any type of debridement occurred, then no clinic visit billing was allowed. If there was no debridement, the clinic visit codes were used because dressings were changed frequently. When enzymatic debridement was performed, only the facility was reimbursed.

^‡Only Allevyn® non-adhesive was used in patients who received CCO. Other dressings were considered standard of care in the treatment of DFU.

^§Healthcare Common Procedure Coding System code.

^¶Each dressing was wrapped after applying CCO or standard-of-care dressing.
