How Do Providers Bill TRICARE?
Send a complete claim to the regional contractor for the patient's TRICARE region within one year of the service, on a CMS-1500 or UB-04. 32 CFR 199.7(d) sets the one-year limit, and the regulation makes the provider responsible for perfecting the claim.

In short: bill the regional contractor for the patient's region, not your own, with every required data item and inside one year. A claim returned for information gets the later of one year or 90 days from the return date, and TRICARE For Life claims go to Medicare first.
How Do Providers Bill TRICARE?
File the claim with the regional contractor for the patient's TRICARE region, on a CMS-1500 for professional services or a UB-04 for facility services, within one year of the service. Under 32 CFR 199.7(d), claims for services provided on or after January 1, 1993 must be filed with the contractor no later than one year after the services are provided, and a late claim waives the right to benefits unless an exception applies.
The regulation also puts the work on you. Section 199.7(a)(3) says the beneficiary, sponsor or the authorized provider acting for the beneficiary is responsible for perfecting the claim, and the contractor is not authorized to prepare one. Here is the order we work in for TRICARE claims.
- Ask for the Uniformed Services identification card. Section 199.7(a)(1) says the patient shall present it to the authorized provider.
- Find the patient's region. The region follows where the patient lives, not where your facility sits, and tricare.mil has a region lookup that uses a ZIP code.
- Confirm your own status. tricare.mil's East Region claims page says that if the provider is not TRICARE-authorized on the service date, the claim will be denied.
- Get preauthorization when the service needs it. Section 199.7(f)(1) says it must be granted before benefits are extended, and without it no benefits are paid unless an exception was granted.
- Send a complete claim to the regional contractor, and do not collect the whole bill up front. Section 199.7(a)(5) says the beneficiary is not required to pay before a claim is submitted.
- For TRICARE For Life, bill Medicare first. Medicare pays its portion and sends the claim to the TFL claims processor, so in most cases you do not file separately with TRICARE.
The TRICARE payer guide lists the contractors and phone numbers by region and the full exceptions table. This post covers the routine around them.
What Must Be on a TRICARE Claim?
A claim missing the minimum data may be returned, so the checklist below is the front-end edit worth building into your scrubber. It comes from 32 CFR 199.7(b), which says claims that are not completed fully and lack the minimum information may be returned.
| Item | What the regulation requires |
|---|---|
| Patient identification | Full name, address, date of birth, relationship to sponsor, identification number and card dates, and the sponsor's name, grade, branch and status |
| Diagnosis | All applicable diagnoses, or a narrative of the symptoms if there is no diagnosis |
| Source of care | The name of the hospital or physician and the full address where care was provided, not a billing address |
| Providers | The attending physician, the referring or ordering physician and the individual who rendered the care, with professional status and provider number if the signer is a different person |
| Dates and status | Specific and inclusive dates of service, inpatient or outpatient status and the dates of any related inpatient stay |
| Each service | Date, procedure code or narrative, and the individual charge for each item on each date |
| Hospitals and institutions | An itemized bill for each day covered, and any absences during an inpatient claim identified by date with the reason |
| DRG-paid hospitals | Principal diagnosis, all secondary diagnoses, significant procedures, discharge status, Medicare provider number and source of admission |
Section 199.7(a)(7) adds a Nonavailability Statement, DD Form 1251, for some locations. When one is required, it must be issued before civilian care and must be submitted with the claim. Rules about when a statement is needed come from the contractor, so ask when you verify.
What Is the TRICARE Filing Deadline, and What Resets It?
The deadline is one year from the date of service. For an inpatient admission, the TRICARE Operations Manual, Chapter 8, Section 3, measures the year from the discharge date for facility charges, while professional services billed by the facility run from the date of service. The tricare.mil claims page gives the same one year for the U.S. and its territories, and three years in other overseas areas.
A returned claim has its own clock. Under 32 CFR 199.7(d)(1), a claim that was filed on time and returned for more information must be resubmitted so the contractor receives it no later than the later of one year after the service or 90 days from the date the claim was returned.
A hospital bills a service from February 10, 2027. The claim is returned for missing information on January 15, 2028. Both deadlines are computed from the regulation.
A different admission shows the facility rule: discharge on March 5, 2027 puts the facility charges due on March 5, 2028, while the physician services the facility bills are due one year from each date of service.
For continuing care, section 199.7(e)(1) says a claim should go in every 30 days, such as for outpatient therapy or private duty nursing. For claims under the DRG-based payment system, the claim may be submitted only after the beneficiary is discharged or transferred. Do not wait for a monthly cycle on those.
What If the Claim Is Already Late?
Ask the contractor for an exception in writing, and document why. Section 199.7(d)(2) lets the director grant exceptions for retroactive eligibility determinations, administrative error by a contractor, mental incompetency of the beneficiary or guardian, delays by other health insurance that the beneficiary did not cause, and other cases the director finds necessary to ensure access to care.
The regulation addresses requests from beneficiaries, who send them to the contractor with a complete explanation, all supporting documents and the specific denied claim. Each request is reviewed on its own merits. Call the contractor before you send anything to find out how a provider submits the request, because that part is not spelled out. The timely filing appeal post shows how to assemble proof of timely filing.
Which TRICARE Denials Are Common, and How Do You Fix Them?
| Denial | Likely cause | Fix |
|---|---|---|
| CO-197: authorization absent | Preauthorization was required and missing, or the service fell outside the approved period. Section 199.7(f) says an approval names the exact services and is generally valid for 30 days | Check the approval dates and services against the claim lines, then ask the contractor to review with the approval attached |
| CO-29: time limit expired | The contractor received the claim after the year, or after the 90 days on a returned claim | Look for proof of an earlier receipt, a written request for benefits (the manual counts one as a claim) or an exception category |
| CO-16: missing information | One of the items in the table above is blank | Complete the claim and resubmit it inside the returned-claim window |
| Provider not authorized on the service date | The provider was not TRICARE-authorized on the date of service | Confirm the status with the regional contractor before you rebill |
If you disagree with an initial determination on a participating basis, reconsideration must be mailed within 90 days of the notice, and the request is filed on the postmark date. The regulation says a nonparticipating provider is not a party to the initial determination and may not appeal. The reconsideration, formal review and hearing levels are in the TRICARE payer guide, and the general method is in the denial management playbook.

01How do providers bill TRICARE?
File a complete claim with the regional contractor for the patient's region, on a CMS-1500 for professional services or a UB-04 for facility services, within one year of the service. For TRICARE For Life, bill Medicare first; Medicare then sends the claim to the TFL processor, so you usually do not file separately.
02What is the TRICARE timely filing limit?
Under 32 CFR 199.7(d), claims must be filed with the contractor no later than one year after the services are provided. Facility charges for an inpatient stay run from the discharge date per the Operations Manual. A claim returned for information must be back within the later of one year or 90 days from the return date.
03Can I bill a TRICARE patient up front?
The regulation says a beneficiary is not required to pay for services before submitting a claim, so do not make the patient pay the full bill and wait for reimbursement. Collect the copay or cost-share amount that applies to your network or participation status, and verify what that is with the regional contractor.
04Can a nonparticipating provider appeal a TRICARE denial?
No. Under 32 CFR 199.10, a nonparticipating provider is not a party to the initial determination and may not appeal. A participating provider can request reconsideration by mailing the request within 90 days of the notice of initial determination, and the request counts as filed on the postmark date.
