I25.710 vs I25.811

Summary

What is different?

Title wording.The titles share “Atherosclerosis of … angina pectoris”; I25.710 says “autologous vein coronary artery bypass graft(s) with unstable” where I25.811 says “native coronary artery of transplanted heart without”.

Registry fact

Can these codes be reported together?

No.I25.710’s entry carries an Excludes1 note covering I25.811: “atherosclerosis of native coronary artery of transplanted heart without angina pectoris (I25.811)”. Both may be reported only when the documentation shows the two conditions are unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Official ruleGuide: Excludes1 vs Excludes2

Is there an Excludes1 relationship?

Yes.I25.710’s tabular entry: “atherosclerosis of native coronary artery of transplanted heart without angina pectoris (I25.811)”. The note covers I25.811.

Official ruleGuide: Excludes1 vs Excludes2

Is there an Excludes2 relationship?

None.Neither entry carries an Excludes2 note that names the other code. I25.710 carries 2 Excludes2 notes and I25.811 carries 2 Excludes2 notes covering other codes; the side-by-side table quotes them.

Official rule

Is one more specific?

No.Neither is a subdivision of the other, and neither title is the unspecified form; they describe different conditions within category I25.

Registry fact

Is one a parent or header code?

No.Both are billable codes, and neither contains the other.

Registry fact

Are there sequencing instructions?

None.Neither entry carries a Code First or Use Additional Code note that names the other.

Official rule

Are there other coding relationships?

None found.No laterality, encounter-phase, Table of Neoplasms, Table of Drugs and Chemicals, or history-versus-active-disease relationship links these codes.

Official guidance behind these answers

• Section I.A.12.a — Excludes1 · applies to: Excludes1

  A type 1 Excludes note is a pure excludes note. It means “NOT CODED HERE!” An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition. An exception to the Excludes1 definition is the circumstance when the two conditions are unrelated to each other. If it is not clear whether the two conditions involving an Excludes1 note are related or not, query the provider. For example, code F45.8, Other somatoform disorders, has an Excludes1 note for "sleep related teeth grinding (G47.63)," because "teeth grinding" is an inclusion term under F45.8. Only one of these two codes should be assigned for teeth grinding. However psychogenic dysmenorrhea is also an inclusion term under F45.8, and a patient could have both this condition and sleep related teeth grinding. In this case, the two conditions are clearly unrelated to each other, and so it would be appropriate to report F45.8 and G47.63 together.

Notes are the code’s own tabular entry, quoted as published. A note that names the other code is the one the verdict above rests on.
