The correct ICD-9-CM diagnosis code for neonatal tooth eruption is 520.6. This code specifically addresses conditions related to the dental issues in infants, including the eruption of teeth during the neonatal period. Neonatal tooth eruption is a unique phenomenon where a tooth is present at birth or erupts shortly thereafter, necessitating a precise coding to appropriately reflect the medical condition.

Understanding this context highlights the relevance of this code for accurately documenting clinical situations and for statistical purposes in tracking neonatal dental issues. In contrast, the other codes listed do not accurately represent this specific condition, making 520.6 the most suitable choice. This reinforces the importance of correctly identifying specific health conditions in patient records, ensuring appropriate treatment and management of neonatal dental health.
