What changes the atherosclerotic heart disease code?
The Alphabetic Index lists these qualifiers under Arteriosclerosis, arteriosclerotic, coronary and Arteriosclerosis, arteriosclerotic, coronary, native vessel. If the record documents one of them, the code changes. Verify the code in the Tabular List before reporting it.

| transplanted heart | I25.811 | Atherosclerosis of native coronary artery of transplanted heart without angina pectoris |
| transplanted heart › bypass graft | I25.812 | Atherosclerosis of bypass graft of coronary artery of transplanted heart without angina pectoris |
| transplanted heart › native coronary artery | I25.811 | Atherosclerosis of native coronary artery of transplanted heart without angina pectoris |
| Arteriosclerosis, arteriosclerotic, coronary, native vessel | ||
| with › angina pectoris | I25.119 | Atherosclerotic heart disease of native coronary artery with unspecified angina pectoris |
| with › ischemic chest pain | I25.119 | Atherosclerotic heart disease of native coronary artery with unspecified angina pectoris |
What else changes the atherosclerotic heart disease code?
I25.10 is for coronary artery disease without angina. If the patient also has angina, use a combination code from I25.11- (for example I25.119, with unspecified angina pectoris) instead — not I25.10 with a separate code from I20.
“ICD-10-CM has combination codes for atherosclerotic heart disease with angina pectoris.”
“When using one of these combination codes it is not necessary to use an additional code for angina pectoris.”
What does the Tabular List say about I25.10?
The instructional notes that govern I25.10, including those it inherits from its category and chapter. An Excludes1 note means the two codes are never reported together.
Inclusion terms
Alternative wording in documentation that is classified to I25.10.
- Atherosclerotic heart disease NOS
Use additional code — inherited from I25
Report an additional code alongside I25.10 to fully describe the condition. I25.10 is sequenced first.
Use additional code — inherited from I25.1
Report an additional code alongside I25.10 to fully describe the condition. I25.10 is sequenced first.
Excludes2 — not included here — inherited from Chapter 9
The conditions below are not part of I25.10, but a patient may have both at the same time. When documentation supports it, I25.10 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
- systemic connective tissue disorders (M30-M36)
- transient cerebral ischemic attacks and related syndromes (G45.-)
Excludes2 — not included here — inherited from I25
The conditions below are not part of I25.10, but a patient may have both at the same time. When documentation supports it, I25.10 and the excluded code may both be reported.
- non-ischemic myocardial injury (I5A)
Excludes2 — not included here — inherited from I25.1
The conditions below are not part of I25.10, but a patient may have both at the same time. When documentation supports it, I25.10 and the excluded code may both be reported.
Code also — inherited from I20-I25
Two codes may be needed to describe the condition fully. Whether I25.10 is sequenced first depends on the reason for the encounter.
- the presence of hypertension (I10-I1A)
Codes, descriptions and Index entries are from the official ICD-10-CM FY2027 release. Guideline text is quoted from the ICD-10-CM Official Guidelines for Coding and Reporting FY 2027. A code must always be verified in the Tabular List before it is reported. Data sources
