Chronic Disease Management Act of 2023

This bill amends the Internal Revenue Code to clarify which preventive health services count as covered under insurance plans for chronic conditions. It defines "preventive care" for chronic diseases as services that are low-cost, supported by medical evidence showing they prevent worsening of the condition or costly complications, and have documented clinical evidence of effectiveness. The law also creates a presumption that an individual has a diagnosed chronic condition if they receive preventive care customarily prescribed for that condition. This change directly affects health insurers and Medicare/Medicaid programs by expanding coverage for specific preventive services aimed at reducing long-term healthcare costs.
