Hi Guest!

Here are some diagnosis coding options for you:

K01.1 - Impacted teeth
K00.6 - Disturbances in tooth eruption

For the extractions:

D7111 - Extraction, coronal remnants - deciduous tooth
D7240 - Removal of impacted tooth - completely bony

As for the CPT code for extractions, there is actually not direct crosscodes we are aware of, so you can either bill the "D" code on the medical claim (many insurers these days will process "D" codes when they are medically necessary services), or you can use the CPT code below and include a narrative report describing the procedure:
41899 - Unlisted procedure, dentoalveolar structures

Hope this helps!
