What cannot be coded together with K08.539?

K08.539 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above K08.539 (K08.53, K08.5) and apply to it just the same.

K08.539

K08.539 — Fractured dental restorative material, unspecified

Billable / specific codeICD-10-CM

K08.539 is a billable, specific ICD-10-CM code for fractured dental restorative material, unspecified. It is valid for submission on a claim.

Excludes1 inherited from the categories above K08.539

These are not written on K08.539, but they bind it: a note on a category applies to every code beneath it. Billing K08.539 with anything listed here is a denial.

Written on K08.53 — Fractured dental restorative material

cracked tooth (K03.81)
traumatic fracture of tooth (S02.5)

Written on K08.5 — Unsatisfactory restoration of tooth

dental restoration status (Z98.811)

Excludes2 inherited from the categories above K08.539

Also inherited, and the opposite of Excludes1: these conditions are not part of K08.539, but a patient can have both, so you may code both.

Written on K08.5 — Unsatisfactory restoration of tooth

endosseous dental implant failure (M27.6-)
unsatisfactory endodontic treatment (M27.5-)

Written on K08 — Other disorders of teeth and supporting structures

dentofacial anomalies [including malocclusion] (M26.-)
disorders of jaw (M27.-)

Risk adjustment

K08.539 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 K08.539 is indexed
