Documentation Required

Product-specific application details: documentation of product lot, size, number of applications, fixation method (sutures, staples, adhesives), and whether single or multiple applications were performed (many devices are single-use and dosage is per cm2 or per mg for particulates).

For use of biologic implants/allografts/xenografts: documentation of patient allergies or sensitivities (e.g., known porcine sensitivity excludes Mediskin), informed consent noting product source (human, porcine, bovine, ovine), and rationale for selection.

When using investigational or off-label applications (e.g., TTAX01 for Wagner grade 3-4 DFUs in trials), document enrollment in clinical trial or detailed justification for off-label use, including prior therapies and expected benefit.

For nerve conduit/wrap use (NeuroMatrix/NeuroMend): documentation of nerve injury characteristics demonstrating suitability (no substantial loss of nerve tissue; ability to achieve gap closure by flexion) and surgical details.

Clinical monitoring and follow-up documentation: serial wound assessments, photographic documentation, monitoring for adverse events (e.g., infection beneath dressings or grafts), and documentation of healing progress (percent area reduction, time to re-epithelialization).

Many products require: 'after the wound bed is prepared with standard debridement methods' — documentation of wound bed preparation and debridement prior to product application is required by product labeling/descriptions.

Apligraf (graftskin), a culture-derived human skin equivalent (HSE): For use with standard diabetic foot ulcer care for the treatment of full-thickness neuropathic diabetic foot ulcers of greater than 6-weeks duration that have not adequately responded to conventional ulcer therapy and which extend through the dermis but without tendon, muscle, capsule or bone exposure; or in conjunction with standard therapy to promote effective wound healing of chronic, non-infected, partial and full-thickness [...]
