Wiki Chiari 1 malformation

[Paula19]

Hope someone can help with CPT codes. Patient had a suboccipital craniectomy for Chiari malformation(61343) with arachnoid ectomy(there was a fair amount of arachnoid olverlying the tonsils which we used fine microsurgical technique to excise) and Thermal shrinkage of the tonsils(superficial and lateral aspects were coagulated aggressively and the tonsil shrunk and ascended cranially. Are there separate codes for the thermal shrinkage of the tonsils and arachnoid ectomy?

Thanks for the help.
