Wiki coding question for a achilles procedure

[tbauknight]

I'm trying to figure out the best codes for this procedure.
Augmentation of left achilles tendon with autogenous flexor hallucis longus and allograft dermal matrix transfer of left hallucis longus to the calcaneus, achilles tendon debridement?

All advise would be helpful.
