Post OP Myocardial Infarction (MI) defined as MI during the PCI admission that was not present at admission or an MI during an inpatient re-admission connected to the PCI admission via acute transfer; ICD-9-CM codes used to identify MIs: 410.xx. ICD-10-CM codes used to identify MIs: I21.0x, I21.1x, I21.2x, I21.3, I22.0, I22.1, I22.8, I22.9, I21.4, I22.2.
Post OP Stroke defined as stroke during the PCI admission that was not present at admission or stroke during an inpatient re-admission connected to the PCI admission via acute transfer; ICD-9-CM codes used to identify Strokes: 997.02, 433.01, 433.11, 433.21, 433.31, 433.81, 433.91, 434.01, 434.11, 434.91. ICD-10-CM codes used to identify Strokes: I63.xx, G97.31, G97.32, I97.81x, I97.82x.
Unplanned re-intervention during the index admission that occurred greater than 30 days or later after the date of the index PCI counting the date of the index PCI as day 1 or during a connected non-elective acute admission. The following situations are considered unplanned re-interventions: Any procedure in the ICD-9-PCS range 35.xx-38.xx or ICD-10-PCS 02xxxxx that was performed using ECC (ICD-9-PCS code: 39.61, ICD-10-PCS codes: 5A1221Z) or off-pump CABG procedure (ICD-9-PCS: 36.1x, ICD-10-PCS: 0210xxx, 0211xxx, 0212xxx, 0213xxx). Any PCI (ICD-9-PCS for IP data: 36.01, 36.02, 36.05, 36.06, 36.09, 00.66; ICD-10-PCS for IP data: 02703xx, 02713xx, 02723xx, 02733xx, 02C03xx, 02C13xx, 02C23xx, 02C33xx, X2C03xx, X2C13xx, X2C23xx, X2C33xx, 02704xx, 02714xx, 02724xx, 02734xx, 02C04xx, 02C14xx, 02C24xx, 02C34xx, X2C04xx, X2C14xx, X2C24xx, X2C34xx; CPT codes for ED data for 2012 or earlier: 92980, 92981, 92982, 92983, 92984, 92995, 92996; CPT codes for ED data for 2013: 92920, 92921, 92924, 92925, 92928, 92929, 92933, 92934, 92937, 92938, 92941, 92943, 92944). Non-elective encounters are unscheduled inpatient admissions or emergency department encounters.

All events are weighted equally.
