About K03.8
K03.8 is the ICD-10-CM diagnosis code for other specified diseases of hard tissues of teeth. It belongs to category K03 (other diseases of hard tissues of teeth), block K00-K14 (diseases of oral cavity and salivary glands) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.
Within K03, choose K03.8 (Other specified diseases of hard tissues of teeth) only when documentation doesn't support a more specific option: excessive attrition of teeth (K03.0), abrasion of teeth (K03.1), erosion of teeth (K03.2), pathological resorption of teeth (K03.3), Hypercementosis (K03.4), ankylosis of teeth (K03.5), deposits [accretions] on teeth (K03.6), posteruptive color changes of dental hard tissues (K03.7) and 1 more.
To report this condition, pick the subcode that matches the documentation: K03.81 (tooth) and K03.89 (teeth).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
