Complete loss of teeth due to oth cause, class IV

This code signifies the complete absence of all natural teeth in either the maxillary or mandibular arch, or both, resulting from a specific, non-traumatic, non-developmental etiology. It indicates a severe form of edentulism where the patient has lost all dentition due to an identifiable cause other than injury or congenital factors, classified as Class IV.

Use this code when documentation clearly states complete edentulism attributed to a specified systemic disease, extensive periodontal disease, or other non-traumatic, non-developmental conditions leading to total tooth loss. Supporting documentation should explicitly mention the underlying cause and confirm the complete absence of teeth.

• Ensure the documentation specifies the "other specified cause" for complete tooth loss; avoid using this code for unspecified etiologies.
• Distinguish from codes for partial edentulism or tooth loss due to trauma (e.g., S03.2XXA).
• Consider sequencing this code after the primary diagnosis if the complete tooth loss is a manifestation or complication of another condition.
