Partial loss of teeth, unspecified cause, class I

This code signifies a condition where an adult patient has experienced the partial loss of teeth, but the underlying cause of this loss is not documented or specified. The "Class I" designation refers to a specific classification of tooth loss, typically indicating missing teeth in the anterior region or a specific pattern of edentulism.

This code is appropriate when a patient presents with partial edentulism, and the clinical documentation clearly states that the etiology of the tooth loss is unknown or has not been determined. It should be used when the dental record indicates a Class I pattern of missing teeth without a specified cause.

• Ensure documentation explicitly states "unspecified cause" for the tooth loss.
• Avoid using this code if a specific cause (e.g., trauma, periodontal disease, caries) is identified; instead, code the specific cause.
• Verify the "Class I" classification is supported by the dental examination findings.
