Hi guest! The current version of diagnosis codes is actually ICD-10 instead of ICD-9 (that transition took place October 1, 2015), so here are some ICD-10 coding options for you below based on what you described: K04.8 – Radicular cyst When you say the tooth was damaged from the cyst, what type of damage? (i can look up coding options for you based on what type of damage the cyst caused). For example, if the tooth was cracked, the ICD-10 code for that is: K03.81 – Cracked tooth.
