Top Claim Submission Errors for Home Health Providers: Error 31018
Reason for error: Typically, home health claims are returned to provider (RTP) for correction with this reason code for one of two reasons:
- There is a span of more than 60 days between the "FROM" and "TO" date submitted on the claim.
- Example 1: "FROM" date billed is March 15 and the "TO" date billed is May 14, which equals 61 days
- Example 2: "FROM" date billed is March 15, and the "TO" date billed is July 12, which equals 120 days
- There is less than 60 days between the "FROM" and "TO" date submitted, and a patient status code "30" appears on the claim.
- Example: "FROM" date billed is March 15 and the "TO" date billed is May 11, which equals 58 days. Patient status code "30" indicates the beneficiary remains a patient of the HHA at the end of the episode; therefore, the span between the "FROM" and "TO" dates cannot be less than 60 days.
Claim processing result: Return to Provider (RTP)
How to prevent/resolve:
- Be aware that under the Home Health Prospective Payment System (HH PPS) the unit of payment is a 60-day episode of care
- Verify the "FROM" and "TO" dates submitted on home health claims to ensure there is never a span of more than 60 calendar days submitted on a final claim (type of bill 329)
- To determine the 60th day of an episode based on the "FROM" date, access the Home Health 60-Day Episode Calendar Schedulequick resource tool.
- If the span of days is less than 60 days, and the patient was discharged, enter the appropriate patient status code as of the "TO" date on the claim
- This code is entered in the "STAT" field found on FISS claim page 01 or form locator 17 on the CMS-1450 form
- A listing of patient status codes is available by accessing the following resources:
- If you are using a billing software that calculates the episode dates and you are receiving this error, address this issue with your software vendor
