Other cardiac arrhythmias - I49
Excludes1: It indicates that the conditions described by two codes cannot occur together in the same patient. These codes are mutually exclusive.
Type 1 Excludes:
- neonatal dysrhythmia (P29.1-)
- sinoatrial bradycardia (R00.1)
- sinus bradycardia (R00.1)
- vagal bradycardia (R00.1)
Excludes2: This note means that the conditions described by two codes are not usually associated with each other but can sometimes occur together.
Type 2 Excludes:
- bradycardia NOS (R00.1)
Code First: This note advises that another code should be sequenced as the principal diagnosis before the code with this note.
Category codeFirst:
- cardiac arrhythmia complicating:
- abortion or ectopic or molar pregnancy (O00-O07, O08.8)
- obstetric surgery and procedures (O75.4)
