Implementation of a Provider's Asthma-specific Note to Optimize Billing in the Pediatric Emergency Department

There is broad variability in provider documentation for asthma encounters within the pediatric emergency department. Inadequate provider documentation leads to discrepancies between the ideal current procedural terminology (CPT) code and the assigned CPT code based on the care provided. Multiple studies demonstrate improvement in medical provider documentation after implementing standardized documentation templates and educational programs. The primary aim of this project was to improve the concordance between the ideal CPT code and assigned CPT code from a baseline of 71% to 85% in 12 months.

We introduced an asthma-specific note template in January 2018. We reviewed a random sample of 20 encounters per month to compare the ideal and assigned CPT codes in the baseline and intervention periods. The primary outcome measure was the percentage of encounters with agreement between ideal and assigned billing. The secondary outcome measure was the percentage of encounters with intravenous magnesium that were billed for critical care. The process measure was asthma note usage. Provider education and Plan-Do-Study-Act (PDSA) cycles continued throughout the intervention period. We used statistical process control to measure changes over time.

We reviewed 740 patient encounters over a 12-month baseline and 25-month intervention period. The average agreement between ideal and assigned CPT code increased from 71% to 89%, with 84% usage of the asthma note template. The percentage of critical care billing for intravenous magnesium increased from 15% to 55%.

Implementation of an asthma-specific provider note template in the pediatric emergency department improved billing optimization and critical care billing.
