Cardiac Pacemaker Diagnosis-Related Groups (DRGs)

The cardiac pacemaker DRGs are revised as of October 1, 1987, to encompass the revised cardiac pacemaker codes (37.70-37.89). Care must be exercised in coding and reporting the cardiac pacemaker codes in order to receive the proper DRG assignment. As explained in the preceding coding guidelines, two codes are required to identify the initial insertion or total replacement of a permanent cardiac pacemaker system: one code to identify the type of device (single-chamber, rate responsive; single-chamber, not specified as rate responsive; or dual-chamber) and one code to identify the insertion of the lead(s) (transvenous atrial, transvenous ventricular...

Article Overview

This article reviews DRG assignment guidance for cardiac pacemaker cases, focusing on how inpatient hospital grouping depends on combinations of cardiac pacemaker procedure codes and the broader diagnosis framework. It is relevant to inpatient coders, DRG reviewers, and compliance staff who need to understand how these cases are categorized under the Medicare grouper logic discussed in the article. The article also references the revised cardiac pacemaker code set, the applicable MDCs and DRGs, and the circumstances in which certain pacemaker procedure codes are treated within the grouping process.

Why This Topic Matters

Pacemaker cases can be grouped differently depending on how procedure coding is reported, which affects DRG assignment and inpatient case classification. Understanding the article helps coders recognize the code combinations and grouping context discussed for these hospital claims.

Article Sections

  1. Revised pacemaker code set and two-code reporting concept

    Introduces the revised cardiac pacemaker code set and the general requirement that pacemaker cases are reported using paired procedure information. The section frames how device and lead components are addressed in the grouping context.

  2. DRGs that require paired pacemaker procedure codes

    Lists the diagnosis-related groups and major diagnostic categories associated with pacemaker implant cases. It also presents the procedure-code combinations used within the DRG grouping discussion.

  3. Single-component pacemaker procedures and Grouper treatment

    Explains the grouping treatment of cases where only part of a pacemaker system is reported. The section describes how the Grouper handles certain pacemaker procedure codes when they do not appear with the related paired procedures.
