AHA Coding Clinic® for ICD-9 - 1989 First Quarter
Understanding Current Pacemaker Technology
Current pacemaker technology has required revisions in the ICD-9-CM codes to describe that technology. Coding guidelines for these revisions which became effective October 1, 1987, can be referenced in theMay-June 1987 issue of Coding Clinic, pages 1-10. This article provides additional information that describes the purpose of pacemaker implantations including the difference between single chamber, dual chamber, rate responsive, and temporary pacemakers. The function of the electrode or lead connected to the pacemaker is also reviewed so that the coder understands the necessity of assigning codes for both the pacemaker insertion and the implantation of the lead. Pacemakers, temporary...

Article Overview
This article reviews current pacemaker technology as it was reflected in ICD-9-CM coding revisions effective October 1, 1987. It discusses pacemaker purpose, basic functions, device categories, lead concepts, and the distinction between temporary and permanent pacing in a coding context. The material is aimed at coders and other health information professionals who need background on pacing technology and the code updates tied to it.
Why This Topic Matters
Pacemaker coding depends on understanding both the device and the lead, as well as the clinical context in which pacing is performed. This article helps readers recognize the technology changes that drove code revisions and the broad categories of pacing procedures discussed in the coding guidance.
Article Sections
-
Temporary Pacemakers
Explains the role of temporary pacing and distinguishes between temporary use in acute care and temporary pacing associated with cardiac surgery. The section also introduces the related coding revision context.
-
Conduction System of the Heart
Summarizes the normal electrical conduction pathway of the heart and describes how conduction abnormalities relate to pacing needs. The section provides clinical background for the article's coding discussion.
-
Pacemaker Functions
Reviews the basic functions of pacemakers and how pacing relates to sensing the heart's own activity. This section gives general operational context for the technology.
-
Types of Pacemakers
Describes the major pacemaker device categories covered in the article and compares their broad characteristics. The section focuses on technology distinctions relevant to coding.
-
Pacemaker Leads
Discusses lead placement approaches, the relationship between the lead and electrode, and common implantation locations. The section provides anatomy and device placement background.
-
Coding Pacemakers and Leads
Addresses the relationship between pacemaker device coding and lead coding under the revised ICD-9-CM framework. The section also notes the historical change in how pacemaker components were coded.
