PR-149 tells you the plan has paid all it ever will for a certain category of care for this patient. Once that lifetime cap is used up, the plan stops paying for that benefit, and the PR group moves the balance to the patient. Most US plans can no longer put lifetime dollar caps on essential health benefits. So when you see CARC 149 today, it’s usually tied to a benefit outside that list, such as fertility treatment, weight-loss surgery or adult orthodontics, or to a plan type that the federal rule doesn’t reach.

In brief: CARC 149 reads “Lifetime benefit maximum has been reached for this service/benefit category.” Confirm which benefit hit the cap and whether that cap is allowed. If it is, tell the patient and bill them. If it isn’t, appeal.

Lifetime limits after the Affordable Care Act
A lifetime limit is a cap on what a plan will pay for a benefit over the whole time a person is covered. Essential health benefits are the ten categories of care, such as hospital stays and prescription drugs, that most plans must cover. HealthCare.gov explains that plans can’t set lifetime dollar limits on those benefits.
A non-dollar limit is a cap counted in visits, cycles or procedures instead of money. That still leaves room for CARC 149 in a few places:
| Situation | Can a lifetime cap apply? |
|---|---|
| A benefit outside the essential list, such as adult orthodontics | Often yes |
| A non-dollar cap, such as one procedure per lifetime | Often yes |
| A plan type outside the rule, such as some short-term plans | It depends on the plan |
| A dollar cap on an essential benefit in a regulated plan | Generally no, so question it |

PR-149 Denial Example: What Happened
Olivia Tran handles billing at Harborview Fertility Center. A patient started a third round of IVF after two earlier cycles. The clinic billed the egg retrieval, 58970, with female infertility (N97.9) to Bayside Employer Health Plan, a fictional employer plan.
The remit denied the line with CAS*PR*149 and remark LQ*HE*N130, “Consult plan benefit documents/guidelines for information about restrictions for this service.” The patient had been told her coverage was good.
Had the plan really hit a lifetime cap, and could the clinic do anything about it? Keep reading, or jump to how the PR-149 denial was resolved.
Remark codes that often go with CARC 149
| RARC | X12 wording |
|---|---|
| N130 | “Consult plan benefit documents/guidelines for information about restrictions for this service.” |
| N117 | “This service is paid only once in a patient’s lifetime.” |
| N23 | “Alert: Patient liability may be affected due to coordination of benefits with other carriers and/or maximum benefit provisions.” |

How to work a PR-149 denial
- Get the plan’s benefit summary. Find the exact lifetime limit and what counts toward it, such as dollars, cycles or procedures.
- Ask for the running total. The plan should be able to show which claims used the cap.
- Check whether the cap is allowed. If the service is an essential health benefit in a regulated plan, a dollar cap may not apply.
- Look for errors. For example, claims from another family member or a denied claim counted by mistake.
- Appeal when the count or the cap is wrong. Include the plan’s own benefit language.
- Tell the patient when the cap is valid. Give a cost estimate and a payment plan before more care.
- Check other coverage. A secondary plan may pick up the cost.
Example scenario (fictional names), part 2
How the PR-149 Denial Was Resolved
Olivia called the plan and asked for the benefit summary and the running total. The employer plan had a lifetime fertility cap of a set dollar amount, and the first two cycles had used most of it. Fertility treatment wasn’t an essential health benefit under this plan, so the cap was allowed.
Fix: no appeal. Olivia gave the patient a written estimate for the rest of the cycle and set up a payment plan, then billed the PR-149 amount to her.
Outcome: the patient chose to go ahead with clear numbers in hand. Harborview now asks every fertility plan for the lifetime total before each new cycle starts.

Worked example (illustrative)
Consider an orthodontic office treating an adult patient. The dental plan has a lifetime orthodontic maximum, and an earlier orthodontist used part of it years ago. The claim denies with PR-149 partway through treatment. The office gets the plan’s history, confirms the earlier claims, and updates the patient’s payment schedule.
Is the patient really responsible?
| Question | If yes | If no |
|---|---|---|
| Is the cap in the plan documents? | Valid if allowed by law | Appeal |
| Is the benefit outside essential benefits, or the cap non-dollar? | Cap likely valid | Ask for a review |
| Were the counted claims correct? | Bill the patient | Ask the plan to fix the count |

Key takeaways
PR-149 means a lifetime benefit maximum for that category has been used up. Check the plan’s limit and running total, make sure the cap is allowed and counted right, and appeal if it isn’t. When it is valid, give the patient a clear estimate before more care.
FAQ
What does denial code PR-149 mean?
The patient reached a lifetime maximum for this kind of care. It reads “Lifetime benefit maximum has been reached for this service/benefit category.”
Can I bill the patient for PR-149?
Yes, when the cap is valid. The PR group makes it the patient’s share.
Are lifetime limits still legal?
Not as dollar caps on essential health benefits in most plans. They can still apply to other benefits or as non-dollar limits.
What’s the difference between CARC 149 and CARC 35?
CARC 35 is a general lifetime benefit maximum. CARC 149 is tied to a specific service or benefit category.
How do I check how much of the cap was used?
Ask the plan for the running total and the list of claims that counted.
Can a secondary plan pay after PR-149?
Often, yes. Send the claim with the primary remit to the secondary plan.
