What CARC 222 actually means
CARC 222 caps the service at the contracted-maximum hours/days/units for the provider in the time period — common in home health, therapy, SNF, and infusion contracts. The cap is contractual, so most denials are not appealable beyond confirming the math. If the cap was misapplied (e.g., prior claims miscounted), submit a corrected claim or dispute with the ledger.
Common root causes
- Provider exceeded the contractual annual/quarterly maximum on this code or category.
- Prior claims in the period were miscounted by the payer's system.
Prevention checklist
- Real-time provider-level utilization counter against contract caps.
- Alert when a provider approaches 80% of contract cap in a period.
Appeal strategy — step by step
Most CARC 222 denials clear faster with the right remediation than with a formal appeal. Work the steps in order and escalate only when a lower-effort path has been ruled out.
- 1Reconcile prior claims against the payer's utilization count; appeal if the payer's count is wrong.
- 2If the cap was correctly applied, the denial is contractual and will not overturn.

How QuickRCM prevents CARC 222
QuickRCM catches the root causes above before the 837 leaves the clearinghouse:
- Claim-scrub rules fire on every root cause listed above — the scrub references the same X12 CAS segment logic that drives the denial, so what the payer checks, QuickRCM checks first.
- When a denial lands, QuickRCM routes it to the correct worker with the documentation bundle already attached (op note, LCD citation, modifier rationale, EOB, primary 835).
- Appeal templates tuned to each CARC (including this one) pull the supporting facts from the claim and fill the bracketed fields automatically.
Frequently asked questions — CARC 222
What does CARC 222 mean?
CARC 222 is an X12 Claim Adjustment Reason Code. The official definition is: "Exceeds the contracted maximum number of hours/days/units by this provider for this period." In plain English, the payer is telling you cARC 222 caps the service at the contracted-maximum hours/days/units for the provider in the time period — common in home health, therapy, SNF, and infusion contracts. The cap is contractual, so most denials are not appealable beyond confirming the math. If the cap was misapplied (e.g., prior claims miscounted), submit a corrected claim or dispute with the ledger.
How do I resolve a CARC 222 (CO-222) denial?
Start with the most common root cause: Provider exceeded the contractual annual/quarterly maximum on this code or category. First step: Reconcile prior claims against the payer's utilization count; appeal if the payer's count is wrong. See the full remediation and appeal checklist on this page before filing a formal appeal.
Is CARC 222 patient responsibility?
No — CARC 222 is typically carried under CO (Contractual Obligation) or OA (Other Adjustment), which means it is the provider's responsibility, not the patient's. Do not bill the patient unless the 835 CAS group code is PR.
What does CARC 222 look like on an EOB or 835 remittance?
On the 835 ERA, CARC 222 appears in Loop 2110 CAS segment as "CAS*CO*222*{amount}". On a paper EOB the same code prints in the Adjustment/Denial Reason column with the X12 description: "Exceeds the contracted maximum number of hours/days/units by this provider for this period." — usually paired with one or more RARC remark codes in the same remittance line for additional context.
Which RARC is paired with CARC 222?
CARC 222 is commonly observed with RARC N435. The RARC narrows the reason — for example, pointing at a missing modifier, an LCD citation, or a specific policy. Fix the underlying CARC first; the RARC usually clears with the corrected claim.
