About coding Beau's syndrome

The ICD-10-CM code for Beau's syndrome is I51.5 (Myocardial degeneration).

Within I51 (complications and ill-defined descriptions of heart disease), I51.5 is specifically for myocardial degeneration. Related codes cover cardiac septal defect, acquired (I51.0), rupture of chordae tendineae, not elsewhere classified (I51.1), rupture of papillary muscle, not elsewhere classified (I51.2), intracardiac thrombosis, not elsewhere classified (I51.3), myocarditis, unspecified (I51.4), Cardiomegaly (I51.7), other ill-defined heart diseases (I51.8) and heart disease, unspecified (I51.9).

Don't report I51.5 together with the conditions in its Excludes1 note: myocardial degeneration due to hypertension (I11.-) and myocardial degeneration due to hypertension and chronic kidney disease (I13.-).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

Don't confuse with (Excludes1 for I51.5)

  • myocardial degeneration due to hypertension (I11.-)
  • myocardial degeneration due to hypertension and chronic kidney disease (I13.-)
