modifier T4 or LT for cpt code 28810

[jenmar]

Hello...I'm not sure which is a more appropriate modifier for cpt code 28810 - amputation, metatarsal, with toe, single (left foot, 5th toe, 5th metatarsal). Modifier T4 for 5th digit or LT for metatarsal? Any help is appreciated!!!

If the metatarsal is involved, I use the -rt or -lt. Proximal phalanx or above, I use the toe - T - codes.

So - the -LT in this case...
