If you mix up the dates on your request for anticipated payment, you'll have to cancel the rejected RAP and start over. So advises regional home health intermediary Cahaba GBA in its September newsletter for providers. Reminder: For a RAP for an initial episode, the "FROM" date (FL 4) and "ADMIT" date (FL 12) "must reflect the date of the first Medicare billable visit in the episode, not the date the referral for home health services was received," Cahaba instructs. For subsequent episodes, the "ADMIT" date stays the same but the "FROM" date changes to the first day of the new episode (day 61, 121, etc.). Plus: "The date billed with the 0023 revenue code line on all RAPs and claims must reflect the date of the first Medicare billable visit in the episode."
