AHA Coding Clinic® for ICD-9 - 1999 Second Quarter
Intrathecal Infusion Pump
The intrathecal infusion pump system is an implantable device used to deliver drug therapy for treatment of chronic pain, severe spasticity of spinal cord origin, and malignant neoplasms. The pump delivers the drug continuously to specific areas of the body, lessens dosage requirements, and reduces the side effects of drug therapy. Some patients that suffered serious sides effects from oral medications, reacted favorably to drugs delivered via the infusion pump. The pump is able to deliver higher concentrations of the appropriate dosage at a scheduled time close to the spinal cord. The system has three basic parts: the pump...

Article Overview
This article explains the basic components and function of intrathecal infusion pump systems and addresses common coding-related situations involving pump management. It is intended for coding professionals and clinicians who need a general understanding of pump-related documentation scenarios, including admission for reprogramming and refilling, replacement, and malfunction issues. The content also touches on diagnosis coding considerations in a pain management context and references specific device- and symptom-related scenarios.
Why This Topic Matters
Intrathecal infusion pump cases often involve device maintenance, symptom management, and diagnosis selection that can affect claim accuracy and medical record interpretation. Understanding the scope of the device and the related clinical scenarios helps coders and reviewers locate the relevant guidance quickly.
Article Sections
-
Overview of the Intrathecal Infusion Pump System
