In the CPT® book, 28400 and 28405 are used when coding a calcaneal

are used when coding a CLOSED treatment of a calcaneal fracture. Closed
Treatment means there is not an incision made over the fracture site. Code
28400 is "without manipulation" and code 28405 is "with manipulation."
Internal fixation is not a closed treatment procedure.
In the CPT® codebook, 25000 and 25001 are for incisions in the tendon
