About coding PAT
The ICD-10-CM code for PAT is I47.19 (Other supraventricular tachycardia).
Within I47.1, choose I47.19 (Other supraventricular tachycardia) only when documentation doesn't support a more specific option: unspecified (I47.10) and inappropriate sinus tachycardia, so stated (I47.11).
Code first tachycardia complicating: abortion or ectopic or molar pregnancy (O00-O07, O08.8) and obstetric surgery and procedures (O75.4).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
