N147 Remark Code: LTC Rate Blocked by Invalid Patient ID

N147 means the payer could not determine the long-term care case mix or per diem rate because the patient ID number on the assignment request was missing, incomplete, or invalid. Without a rate, the long-term care claim could not be priced.

What N147 means

Many programs that pay nursing facilities, especially Medicaid, pay a rate tied to the resident, either a case mix level based on assessment data or a set per diem. The facility requests that rate through an assignment submission. N147 tells the facility that the request could not be matched to a resident because the patient ID on it was wrong or missing, so the payer has no rate to apply.

Unlike most identification denials, the problem is on the rate request, not necessarily on the claim itself.

Common causes

  • The resident’s program ID was mistyped on the assignment request.
  • The resident’s ID changed (for example, after a new eligibility determination), and the old one was used.
  • The request was filed before the resident had a program ID, using a placeholder.
  • A field-length or format error truncated the ID.

What to do

  1. Pull the resident’s current ID from the eligibility system and compare it with the assignment request.
  2. Correct and resubmit the assignment request through the program’s process.
  3. Confirm the rate is assigned for the correct dates.
  4. Reprocess the claim once the rate is in place, following the program’s resubmission rules.

How to prevent it

Verify each new resident’s program ID before submitting assessments or rate requests, and recheck it whenever eligibility is renewed. Use the same identifier source for admissions, assessments, and billing so the numbers cannot drift apart.

Codes that may appear with N147

  • CO-140 (Patient/Insured health identification number and name do not match.): The patient's health identification number and name do not match.

N147 FAQ

What is the assignment request?

The submission a long-term care facility makes to the program to establish or assign the resident's rate, such as a case mix classification or per diem. The exact name and format depend on the program.

Which ID number is meant?

The resident's identification number with the program, usually the Medicaid recipient ID. Check that it matches the resident's current eligibility record.

Do I need to resubmit the claim too?

Usually the assignment request must be corrected first. Once a rate is assigned, the claim can be reprocessed or resubmitted according to the program's instructions.
