Partial loss of teeth due to other specified cause, class IV

This code signifies the absence of some, but not all, teeth in a patient's mouth, resulting from a cause other than congenital, trauma, or periodontal disease. Specifically, it indicates a Class IV partial edentulism, which typically involves the absence of posterior teeth on both sides of the arch, with an anterior edentulous area. This condition can impact mastication, speech, and facial aesthetics.

Apply this code when documentation clearly states partial tooth loss due to a specified etiology not covered by other K08.4 codes (e.g., systemic disease, iatrogenic causes, or idiopathic reasons). The Class IV classification must be explicitly documented or clearly inferable from the description of the missing teeth (e.g., bilateral posterior and anterior edentulous areas).

• Ensure the documentation specifies a cause for tooth loss other than congenital, traumatic, or periodontal.
• Verify that the pattern of missing teeth aligns with a Class IV partial edentulism (bilateral posterior and anterior edentulous areas).
• Do not use this code for complete edentulism or for partial tooth loss due to congenital absence (K00.0), trauma (S03.2-), or periodontal disease (K08.41-).
