Marfan syndrome, unspecified

This code identifies Marfan syndrome, a genetic disorder affecting connective tissue, when the specific type or manifestation is not documented. It is characterized by a range of signs and symptoms primarily involving the cardiovascular, ocular, and musculoskeletal systems.

Use this code when Marfan syndrome is diagnosed, but the medical record does not specify a particular manifestation or subtype. This is appropriate for initial diagnoses or when comprehensive genetic testing or detailed clinical evaluation results are pending or unavailable. Documentation should clearly state "Marfan syndrome" without further specificity.

• Avoid using this code if more specific Marfan syndrome codes (e.g., with cardiac or ocular manifestations) can be assigned based on documentation.
• Always review the entire medical record for any mention of specific organ involvement that would allow for a more precise code.
• Consider querying the provider if the documentation is ambiguous and a more specific diagnosis of Marfan syndrome is clinically indicated.
