About coding Pre-eruptive color change
The ICD-10-CM code for Pre-eruptive color change is K00.8 (Other disorders of tooth development).
Within K00, choose K00.8 (Other disorders of tooth development) only when documentation doesn't support a more specific option: Anodontia (K00.0), Supernumerary teeth (K00.1), abnormalities of size and form of teeth (K00.2), Mottled teeth (K00.3), disturbances in tooth formation (K00.4), hereditary disturbances in tooth structure, not elsewhere classified (K00.5), disturbances in tooth eruption (K00.6), Teething syndrome (K00.7) and 1 more.
The conditions in its Excludes2 note aren't part of K00.8, but may be coded alongside it if the patient has both: posteruptive color changes (K03.7).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
