Hi Guest! You may consider using the medical CPT code instead of the “D” code: D7921 – collection and application of autologous blood concentrate product can be crosscoded to: 0232T – Injection(s), platelet rich plasma, any site, including image guidance, harvesting and preparation when performed Just a heads up, many medical insurers do consider PTP not medically necessary at this point in time, so you may need to appeal and explain the reasoning it is medically necessary. Hope this helps!
