When we audit providers, we recommend 90% accuracy. However, I always stress that if the provider's record were to be audited by a payer, they would likely not pay the claim if the record is inaccurate. Also, if the OIG were to audit a sample and find more than a 5% error rate (so 95% accuracy) they would likely investigate further. Its a good practice to have this in a compliance plan of what the acceptable accuracy rate for the practice is. Some practices are very lenient and allow 80%. I do not recommend anything lower than that.
