N130 is a remark code, not a denial on its own. It tells you the plan has a restriction on this service, such as a limit, an exclusion or a condition, and points you to the plan's benefit documents. Read the reason code it comes with to know what happened.
The official wording
The X12 Remittance Advice Remark Code list defines N130 as: "Consult plan benefit documents/guidelines for information about restrictions for this service."
What N130 is telling you
Remark codes add detail to a reason code. N130 is broad: it says a benefit rule applies and the details are in the plan's documents. You will often see it with PR-204 (not covered), 119 (benefit maximum) or PR-96 (non-covered charge).
Send us the list: payer, date of service, denial code and amount. No patient names needed. We will tell you which claims can still be fixed, which need an appeal, and which deadlines are close. Free, usually within 2 business days. Want the full picture? Get a free 90-day denial audit from your ERA files.

What to do
- Read the reason code on the same line.
- Check the patient's specific plan benefits, through the portal or by calling, for the restriction.
- If the restriction does not apply, ask for reprocessing or appeal. If it does, follow the group code on who owes.
CARC codes that come with N130
N130 is a remark code, so it always rides along with a reason code. The reason code tells you what happened. N130 tells you to look in the plan's benefit rules for the restriction that caused it.
| Pair | What it usually means | Bill the patient? |
|---|---|---|
| PR-96 + N130 | Service not covered under this plan | Usually yes |
| CO-96 + N130 | Not covered, and you cannot bill the patient (often a missing waiver) | No |
| CO-119 or PR-119 + N130 | The benefit maximum for the period was reached, such as a yearly visit limit | Depends on the group code |
| CO-151 + N130 | More services than the plan allows in a period | Usually no |
| PR-204 + N130 | Service not covered under the patient's current benefit plan | Usually yes |
An N130 example
| Line on the remittance | Amount | What it means |
|---|---|---|
| Billed charge | $95.00 | A physical therapy visit |
| PR-119 with N130 | $95.00 | The plan's yearly visit limit was already used |
| Paid by payer | $0.00 | Nothing paid |
The plan covers 20 therapy visits a year, and this was visit 21. N130 points you to the benefit document that sets that limit. With PR, the patient owes it. With CO, you would have to write it off.
How to work an N130 denial
- Read the reason code first. N130 only explains, the reason code decides.
- Pull the patient's benefit summary or call the payer and ask: which restriction applied, and is there an exception or prior authorization route?
- If the restriction does not apply (wrong visit count, wrong plan year), send a corrected claim or a reconsideration with proof.
- If it does apply, bill the patient only when the group code is PR, or when the patient signed a waiver.
- Add the restriction to your eligibility notes so the front desk catches it next time.
N130 checklist
- ☐ You know which reason code came with N130.
- ☐ You checked the plan's limit or exclusion for this service.
- ☐ You know whether the group code lets you bill the patient.
- ☐ The limit is noted for future visits.
N130 on Medicare claims: ABN and modifiers
On a Medicare claim, whether the patient owes depends on the modifier you put on the line before you sent it.
| Modifier | What it tells Medicare | Who pays if denied |
|---|---|---|
| GA | A signed ABN is on file for a service you expected Medicare to deny as not reasonable and necessary. | The patient, if the ABN was valid. |
| GZ | You expected a denial but did not get an ABN. | You. The patient cannot be billed. |
| GY | The service is not a Medicare benefit at all (statutorily excluded). | The patient. No ABN is required. |
| GX | A voluntary ABN was given for an excluded service. | The patient. |
An ABN only works if the patient signed it before the service, it names the service, and it gives a real reason Medicare may not pay. A blanket ABN signed by every patient does not count.
What to ask when you call the payer about N130
- Which benefit rule or exclusion was applied to this line?
- Where is that rule written: the member's plan document, a medical policy, or a visit limit?
- Is there an exception, prior authorization or medical necessity review that would change the decision?
- Does the patient owe this amount, or is it a provider write-off?
- Can I get the call reference number?
Write the answers in the patient's account so the front desk can warn the patient before the next visit.
Questions people ask about N130
Is N130 a denial?
No. It is a remark code that explains the reason code next to it.
Where are the plan benefit documents?
In the payer's provider portal benefit details, the patient's summary of benefits, or by calling the payer's provider line.
What is the N130 remark code description?
"Consult plan benefit documents/guidelines for information about restrictions for this service." It means a plan rule, such as a visit limit or exclusion, caused the denial.
Can I appeal an N130 denial?
Only if the restriction was applied by mistake, for example the visit count is wrong. If the plan really excludes or limits the service, an appeal rarely works.
Can I bill the patient for an N130 denial?
Look at the group code on the same line. With PR, the patient owes it. With CO, you cannot bill the patient unless they signed a valid waiver or, for Medicare, an ABN before the service.
Does an ABN let me bill a Medicare patient after N130?
Yes, if the ABN was signed before the service, named the service, and the claim line carried modifier GA. Without a valid ABN, a medical necessity denial stays with the provider.
