I25.752 is the ICD-10-CM diagnosis code for atherosclerosis of native coronary artery of transplanted heart with refractory angina pectoris. It belongs to category I25 (chronic ischemic heart disease), block I20-I25 (ischemic heart diseases) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within I25.75 (atherosclerosis of native coronary artery of transplanted heart with angina pectoris), I25.752 is specifically for atherosclerosis of native coronary artery of transplanted heart with refractory angina pectoris. Related codes cover unstable angina (I25.750), with documented spasm (I25.751), other forms of angina pectoris (I25.758) and unspecified angina pectoris (I25.759).

Use an additional code to identify: chronic total occlusion of coronary artery (I25.82), exposure to environmental tobacco smoke (Z77.22), history of tobacco dependence (Z87.891), occupational exposure to environmental tobacco smoke (Z57.31), tobacco dependence (F17.-) and 1 more.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 302 (Atherosclerosis with MCC, relative weight 1.1984) and DRG 303 (Atherosclerosis without MCC, relative weight 0.6612), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.

It was added in FY2023, effective October 1, 2022.
