I25.709 — Atherosclerosis of coronary artery bypass graft(s), unspecified, with unspecified angina pectoris
Is I25.709 billable?
Yes, but I25.709 is an unspecified code. I25.709 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, I25.709 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting I25.709 — the more specific alternatives are listed below.

How is I25.709 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to I25.709. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Arteriosclerosis, arteriosclerotic › coronary › bypass graft › with › angina pectoris (diffuse) (obliterans) (of) (senile) (with calcification)
- Arteriosclerosis, arteriosclerotic › coronary › bypass graft › with › ischemic chest pain (diffuse) (obliterans) (of) (senile) (with calcification)
Excludes1 — never code together
The conditions below can never be reported together with I25.709 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- unspecified angina pectoris without atherosclerosis of coronary artery bypass graft (I20.9)
Excludes1 — never code together — inherited from I25.7
The conditions below can never be reported together with I25.709 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from I25
Report an additional code alongside I25.709 to fully describe the condition. I25.709 is sequenced first.
Use additional code — inherited from I25.7
Report an additional code alongside I25.709 to fully describe the condition. I25.709 is sequenced first.
Excludes2 — not included here — inherited from Chapter 9
The conditions below are not part of I25.709, but a patient may have both at the same time. When documentation supports it, I25.709 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 I25.709, but a patient may have both at the same time. When documentation supports it, I25.709 and the excluded code may both be reported.
- non-ischemic myocardial injury (I5A)
Code also — inherited from I20-I25
Two codes may be needed to describe the condition fully. Whether I25.709 is sequenced first depends on the reason for the encounter.
- the presence of hypertension (I10-I1A)
How long has I25.709 existed?
I25.709 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
