The sensitivity of hospital coding to prices: evidence from Indonesia
The sensitivity of hospital coding to prices: evidence from Indonesia (Springer).
This study examines a newly introduced DRG system in Indonesia. We use secondary data for 2015 and 2017 from Jaminan Kesehatan Nasional (JKN), a patient level dataset for Indonesia created in 2014 to record public and private hospitals claims to the national health insurance system to investigate whether
there is an association between changes in tariffs paid and
the severity of inpatient activity recorded in hospitals. We find a consistent
small, positive and statistically significant correlation between changes in
tariffs and changes in concentration of activity, indicating discretionary but
limited coding behaviour by hospitals. The results indicate that reducing price
differentials may mitigate discretionary coding, but that the benefits of this
are limited and need to be compared to the potential risk of having to rebase
all prices upwards.
