Partial loss of teeth, unspecified cause, class IV

This code signifies the absence of some, but not all, natural teeth in a patient, where the underlying reason for the tooth loss is not documented. Specifically, it indicates a Class IV Kennedy classification, meaning there is a single edentulous area located anterior to the remaining natural teeth, which crosses the midline.

Use this code when documentation clearly indicates partial tooth loss with an unspecified etiology and a Class IV Kennedy classification. This typically applies to patients presenting for prosthetic rehabilitation (e.g., partial dentures, bridges) where the cause of tooth loss (e.g., trauma, caries, periodontal disease) is not specified in the record. Supporting documentation would include dental examination findings noting missing teeth and the Kennedy classification.

• Ensure the documentation explicitly states "unspecified cause" for tooth loss; otherwise, a more specific code (e.g., K08.41-K08.49) should be used.
• Verify the Kennedy Class IV designation, which describes a single anterior edentulous space crossing the midline.
• Do not use this code if the patient is completely edentulous; refer to codes within K08.401 or K08.402 for total tooth loss.
