In April, the Chiropractic Office Billing Precision Index (BPI) dropped by 0.1 points below its March mark. Overall, April BPI reached 15.6, 2.1 better than the national average of 17.7.

In contrast to the March index, which kept 90 percent of membership unchanged since January, the April index replaced 30 percent of its members. All three new members are Blue Cross Blue Shield payers. The most notable new member is Blue Cross Blue Shield Michigan, which debuted in the second (!) place at impressive 8.3. The other new members are BCBS North Carolina and BCBS Pennsylvania, which entered the index at the traditional bottom of the index. Note that BCBS Illinois maintained its top placement but Medicare New Jersey, CIGNA and Aetna demonstrated downward mobility. Worst of all performed Medicare South Carolina, Blue Cross Blue Shield Georgia, and Medicaid Illinois, which lost their index membership entirely.

BPI is a key billing performance characteristic, as it is a proxy of the claims that are never paid. BPI = 15.6 means that the average of ten top performing payers working with Billing Precision clients have 15.6% of Accounts Receivable beyond 120 days. Chiropractic office managers use the rule-based index to benchmark their billing performance and guide its improvement over time. Rule-based benchmarking also allows for the identification of elite payers, those that perform best in comparison to every payer in the country, as shown by the index-driven ranking.
