Unspecified constitutional state in development

This code signifies a general, non-specific developmental delay or constitutional issue in a patient, where the exact nature or cause of the developmental problem is not yet determined or clearly defined. It indicates a recognized deviation from typical development without a specific diagnosis.

Use this code when a physician documents a global developmental delay, a "constitutional state in development," or a "failure to thrive" in a pediatric patient, and further diagnostic workup is pending or has not yielded a more specific diagnosis. It is appropriate for initial encounters where a developmental concern is identified but not fully characterized.

• This is a highly non-specific code; aim for a more definitive diagnosis whenever possible.
• Avoid using this code if a more specific developmental delay (e.g., speech, motor) or a specific genetic/syndromic diagnosis is known.
• Expect to see this code used primarily for initial assessments or as a placeholder while a diagnostic process is underway.
