CO-119 and PR-119: when the nutrition benefit runs out
By Javier Alvarez · Updated · 4 min read
| Official description | Benefit maximum for this time period or occurrence has been reached. |
|---|---|
| PR-119 | Patient responsible: bill per your financial policy |
| CO-119 | Provider responsible: write off unless your contract says otherwise |
| Medicare MNT | 3 hours the first year, 2 hours each year after; more with a new referral |
| Common remark codes | N362 (units over maximum), N640 (frequency exceeded), N130 |
| Fix route | Verify the count; appeal only if visits were miscounted |
A 119 denial usually lands on a follow-up the patient was counting on, weeks after the visit. Everything about the claim can be right, the same shape as the ones that paid before, and it still comes back unpaid, because the plan's counter hit zero. The fix is less about the claim and more about knowing the count before you book.
What 119 means (and why the group code matters)
The X12 CARC list defines code 119 as:
"Benefit maximum for this time period or occurrence has been reached."
The group code decides who pays:
- PR-119: the plan says the patient is responsible. You bill the patient under your financial policy.
- CO-119: the provider is responsible. In network, that usually means a write-off, because the contract does not let you bill the member for amounts the payer assigns to you.
119 often travels with a remark code. We have seen a commercial plan return PR-119 with N362 ("The number of Days or Units of Service exceeds our acceptable maximum.") on a 97803 follow-up whose structure was identical to earlier paid claims. Nothing was wrong with the claim; the patient's annual nutrition allowance was used up. N640 ("Exceeds number/frequency approved/allowed within time period.") is another common partner.
How payers cap nutrition therapy
Caps come in several shapes, and the shape changes how fast a patient burns through them:
| Cap type | How it counts | What to watch |
|---|---|---|
| Visits per plan year | Each date of service is one visit, regardless of length | Some plans count 97802 and 97803 together |
| Units per year | Each 15-minute unit counts | A 60-minute visit uses four units at once |
| Hours per year | Medicare MNT: 3 hours the first year, 2 hours each year after | Initial assessments eat the hours fastest |
| Dollar maximum | Rare for nutrition, seen in some plans | Allowed amounts, not your charges, count |
| Shared caps | The same counter as other nutrition providers, or a plan wellness program | Visits with another RD earlier in the year count |
Medicare. The MNT benefit is three hours in the first year and two hours in each later year (NCD 180.1). The treating physician can order additional hours when there is a change in medical condition, diagnosis or treatment regimen (42 CFR 410.132); those are billed with G0270 (individual) or G0271 (group) rather than 97803. See our G0270 and G0271 guide. Also remember the plan year is not always the calendar year: Medicare's first MNT episode can be a 12-month period when coordinated with diabetes self-management training.
Commercial plans set their own limits, and many do not publish them in their medical policies. The only reliable source is the member's benefits, confirmed on a call and written down with the representative's name and reference number.
How to fix a 119 denial
- Confirm the count. Call the payer and ask how many visits or units were applied this plan year, on which dates and by which providers. Misapplied visits happen: a denied or voided claim can still count, and another provider's visit can be applied to the wrong benefit.
- If the count is wrong, ask the payer to reprocess, or appeal with your own visit log and the benefit quote you received before the visit (with its reference number). Our post on when a payer quoted the wrong benefits covers that appeal.
- If the count is right, there is nothing to fix on the claim:
- PR-119: bill the patient per your financial policy.
- CO-119: write it off, unless your contract allows a signed waiver collected before the visit.
- Medicare: if the patient's condition, diagnosis or treatment has changed, ask the physician for a referral for additional hours. For services you expect Medicare to deny as over the limit, review the ABN rules before the next visit, not after.
- Do not switch codes to dodge the cap. Billing 99401-99404 or S9470 instead of 97803 is only legitimate if the documented service meets that code's definition and the plan covers it for dietitians. Otherwise it is misbilling.
How to prevent CO-119 and PR-119
- Ask the four cap questions on every benefits check: Is there a limit on nutrition visits, units or hours? Per what period (calendar or plan year)? How many are used? Are they shared with other providers or programs?
- Don't rely on the 271 alone. Electronic eligibility checks confirm coverage but often omit nutrition visit counts; see electronic eligibility checks (270/271).
- Keep your own counter per patient per benefit period, and warn the patient before the last covered visit.
- Re-verify at plan renewal. Counters reset, and so do plan rules.
- Plan the care around the cap. Front-load the assessment and critical follow-ups, then offer a clear self-pay rate for visits beyond the limit, agreed in writing before those visits.
