About coding beats ectopic
The ICD-10-CM code for beats ectopic is I49.49 (Other premature depolarization). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I49.49.
Within I49.4, choose I49.49 (Other premature depolarization) only when documentation doesn't support a more specific option: unspecified premature depolarization (I49.40).
Code first cardiac arrhythmia complicating: abortion or ectopic or molar pregnancy (O00-O07, O08.8) and obstetric surgery and procedures (O75.4).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
