All primary claims must be filed within 30 days of the date services were provided.
HNS recommends that original claims be filed to HNS within 1-3 days from the date service was rendered but in no condition, later than 30 days from date of service.
Please remember that timely filing limits vary among payors and limits on timely filing should be obtained when you verify benefits for each patient. Making sure claims are filed within that time frame will reduce your denials.
