Which MS-DRGs does I25.811 group to?
I25.811 sits in MDC 05 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

Excludes1 — never code together
The conditions below can never be reported together with I25.811 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- atherosclerosis of native coronary artery of transplanted heart with angina pectoris (I25.75-)
Inclusion terms
Alternative wording in documentation that is classified to I25.811.
- Atherosclerosis of native coronary artery of transplanted heart NOS

Excludes2 — not included here — inherited from I25.81
The conditions below are not part of I25.811, but a patient may have both at the same time. When documentation supports it, I25.811 and the excluded code may both be reported.
- atherosclerotic heart disease of native coronary artery without angina pectoris (I25.10)
Code also — inherited from I20-I25
Two codes may be needed to describe the condition fully. Whether I25.811 is sequenced first depends on the reason for the encounter.
- the presence of hypertension (I10-I1A)
How long has I25.811 existed?
