In simple words: An embedded tooth is completely covered by gum tissue. An impacted tooth is one that is unable to erupt fully because it is blocked by another tooth or soft tissue.

Embedded and impacted teeth are teeth that have failed to erupt into the mouth completely or partially within the expected timeframe.This can affect both primary (baby) teeth and permanent (adult) teeth.

Example 1: A 17-year-old patient presents with an impacted wisdom tooth that is causing pain and swelling., A 9-year-old patient has an embedded canine tooth that has not erupted., An adult patient has an impacted premolar tooth preventing the eruption of adjacent teeth.

Documentation should include radiographic evidence (X-rays) confirming the presence and location of the embedded or impacted tooth, clinical examination findings describing any associated symptoms (e.g., pain, swelling, infection), and treatment plan.

** For impacted teeth, the specific tooth should be specified using the appropriate fourth character (e.g., K01.1 Impacted teeth). In outpatient settings, the ICD-10 code should be appended with a diagnostic confidence indicator (A, G, V, or Z).
