K08.3 — Retained dental root
K08.3 is a billable, specific ICD-10-CM code for retained dental root. It is valid for submission on a claim.
Excludes2 inherited from the categories above K08.3
Also inherited, and the opposite of Excludes1: these conditions are not part of K08.3, but a patient can have both, so you may code both.
Risk adjustment
K08.3 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
How K08.3 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to K08.3.
