ICD10 code of Amelogenesis Imperfecta and ICD9 code

Amelogenesis Imperfecta is classified under the ICD-10 code K00.5 (Hereditary disturbances in tooth structure, not elsewhere classified) and the ICD-9 code 520.5 (Hereditary disturbances in tooth structure). These codes are used by healthcare providers and insurance companies to identify and document this rare condition characterized by abnormal enamel formation.

What is the clinical classification of Amelogenesis Imperfecta?

Amelogenesis Imperfecta is a group of hereditary conditions that affect the formation of tooth enamel, leading to teeth that are unusually small, discolored, pitted, or prone to rapid wear and breakage. Because Amelogenesis Imperfecta affects the structure of the enamel, it is categorized under dental developmental disorders. In the ICD system, it is grouped with other hereditary disturbances in tooth structure, reflecting its genetic origins.

Is Amelogenesis Imperfecta hereditary?

Yes, Amelogenesis Imperfecta is a genetic disorder that can follow several inheritance patterns, including autosomal dominant, autosomal recessive, or X-linked. Mutations in specific genes, such as AMELX, ENAM, and FAM83H, are frequently identified in patients. Understanding the specific genetic mutation is crucial for family planning and clinical management.

How is the severity of Amelogenesis Imperfecta categorized?

The severity and presentation of Amelogenesis Imperfecta vary significantly among patients. Clinicians generally classify the condition into four major types based on the clinical phenotype of the enamel:

• Type I (Hypoplastic): The enamel layer is thin but hard.


• Type II (Hypomaturation): The enamel is normal in thickness but soft and prone to chipping.


• Type III (Hypocalcified): The enamel is soft and easily abraded, often appearing yellow or brown.


• Type IV (Hypomaturation-hypoplasia with taurodontism): A combination of the above features accompanied by enlarged pulp chambers.
