ICD-10 Code E71.440 – Ruvalcaba-Myhre-Smith syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E71.440 – Ruvalcaba-Myhre-Smith syndrome
What it is
E71.440 identifies Ruvalcaba-Myhre-Smith syndrome, a rare inherited disorder. Use it when the record specifically names this syndrome as the diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Reports may include developmental delay, characteristic physical findings, and overgrowth or hamartomatous changes described by the treating clinician.
When to use this code
Use this code when the provider documents Ruvalcaba-Myhre-Smith syndrome as confirmed, suspected, or being evaluated. It is also appropriate when the note clearly links the patient’s findings to this named syndrome. If the chart only mentions a broader genetic or overgrowth disorder, check documentation before coding.
Do not use for
Do not use this code for nonspecific developmental delay, isolated growth findings, or other hereditary syndromes without explicit documentation. Check documentation if the diagnosis is uncertain or abbreviated.
Coding tip
Code the named syndrome only when the provider states it directly; otherwise, query for clarification before assigning E71.440.
