N890 Remark Code: EVV Data Requirements Not Met

N890 means the Electronic Visit Verification (EVV) data for the service did not meet the payer's data element requirements. One or more required pieces of visit information, such as the time in and out or the location, was missing or invalid, so the claim could not be matched to a valid visit.

What N890 means

Home care agencies that serve Medicaid members record each visit in an Electronic Visit Verification system, usually through a caregiver’s phone app, a telephone check-in, or a device in the home. Before paying a claim, the payer checks it against that visit record.

N890 means a visit record exists but is not complete enough. The payer found one or more required data elements missing or invalid. Without them, it cannot confirm the service happened as billed.

Common causes

  • The caregiver did not clock out, so the end time is missing.
  • The visit was entered manually without a required reason code or supervisor approval.
  • The location did not verify, for example GPS was off.
  • The service code or member ID in the visit record differs from the claim.
  • The caregiver’s identifier is missing or not registered in the state system.

How to fix it

  1. Open the visit in your EVV system and look for exceptions or incomplete fields.
  2. Correct the record under your state’s visit maintenance rules, including any documentation needed for manual edits.
  3. Make sure the corrected data is transmitted to the state aggregator or payer.
  4. Resubmit the claim after the visit shows as verified. Use frequency code 7 if the payer requires a replacement claim.
  5. Check timely filing before the correction window closes.

How to prevent it

Run a daily exception report and resolve incomplete visits before billing. Caregiver training on clocking in and out properly removes most of these errors.

N890 FAQ

Which data elements does EVV require?

The 21st Century Cures Act requires EVV systems to capture the type of service, the individual receiving it, the date, the location, the individual providing it, and the start and end times. States and plans may add their own requirements.

Which services need EVV?

Federal law requires EVV for Medicaid personal care services and home health care services. States decide exactly which service codes are included.

Can I just rebill the claim?

Only after the EVV record is corrected in the state or vendor system. Rebilling without fixing the visit data will usually produce the same denial.
