Final answer:
The American Hospital Association was not responsible for the development of ICD-9-PCS; this was a federal task undertaken by the Centers for Medicare and Medicaid Services (CMS).
Step-by-step explanation:
The statement that the American Hospital Association is responsible for the development of ICD-9-PCS is false. The ICD-9-PCS (International Classification of Diseases, Ninth Revision, Procedure Coding System) was developed for the Centers for Medicare and Medicaid Services (CMS). ICD-9-PCS was used primarily in the United States for hospital inpatient procedures before being replaced by ICD-10-PCS in October 2015. The responsibility of developing and maintaining the ICD-9-PCS was not with the American Hospital Association; rather, it was a federal task taken up by CMS to allow for more effective healthcare management, reimbursement, and clinical quality.
