About ICD-10-CM Code I50 (Heart failure)
ICD-10-CM code I50 is a billable or specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2025 edition of ICD-10-CM I50 became effective on October 1, 2024.
This page provides detailed information about I50 - Heart failure. It includes common terminology, coding guidelines such as "Includes," "Excludes1," and "Excludes2" notes, and information on required 7th characters. Utilizing this information correctly is essential for accurate medical coding and claims submission for conditions like Heart failure.
