Other diseases of hard tissues of teeth (K03)

The ICD-10 code section K03 covers a variety of conditions affecting the hard tissues of teeth, such as enamel and dentin. These codes are used to classify dental issues like excessive tooth wear, erosion, resorption, and other specific enamel and dentin diseases.

Codes within K03 describe diverse conditions including K03.0 for excessive attrition (wear from grinding or chewing), K03.1 for abrasion (tooth surface loss from external friction), and K03.2 for erosion (chemical loss often from acid exposure). Other codes like K03.3 cover pathological resorption of teeth where tooth structure is broken down, and K03.4 in hypercementosis, an abnormal buildup of cementum on the tooth roots. K03.6 includes deposits or staining on teeth related to poor oral hygiene or habits, while K03.7 describes changes in color after tooth eruption from various causes. The section also includes codes for cracked teeth (K03.81) and tooth sensitivity (K03.89). The K03.9 code is for unspecified diseases of hard tooth tissues, helping clinicians document dental caries related to structural defects. This range is essential for coding specific dental hard tissue diseases not covered elsewhere, aiding accurate diagnosis and treatment documentation.

Instructional Notations

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Dental Calculus

Abnormal concretion or calcified deposit that forms around the teeth or dental prostheses.

Hypercementosis

A regressive change of teeth characterized by excessive development of secondary cementum on the tooth surface. It may occur on any part of the root, but the apical two-thirds are most commonly affected. (Dorland, 27th ed)

Tooth Loss

The failure to retain teeth as a result of disease or injury.
