Claims adjudication

National Provider Identification (NPI)

We accept the NPI on all HIPAA transactions, including the HIPAA 837 professional and institutional (paper and electronic) claim submissions. A valid NPI is required on all covered claims (paper and electronic) in addition to the TIN. For institutional claims, include the billing provider National Uniform Claim Committee (NUCC) taxonomy. We will accept NPIs submitted through any of the following methods:

  • Online:
  • Phone: 1-877-842-3210 through the United Voice Portal, select the “Health Care Professional Services” prompt. State “Demographic changes.” Your call will be directed to the Service Center to collect your NPI, corresponding NUCC Taxonomy Codes, and other NPI-related information.

Level-of-care documentation and claims payment

Claims are processed according to the authorized level of care documented in the authorization record, reviewing all claims to determine if the billed level of care matches the authorized level of care.

If the billed level of care is at a higher level than the authorized level of care, we pay you the authorized level of care. You may not bill the member for any charges relating to the higher level of care. If the billed level of care is at a lower level than authorized, we pay you based on the lower level of care, which was determined by you to be the appropriate level of care for the member.

Level of specificity — use of codes

To track the specific level of care and services provided to its members, we require health care providers to use the most current service codes (i.e., ICD-10-CM, UB and CPT codes) and appropriate bill type.

Member financial responsibility

Verify the eligibility of our members before you see them and obtain information about their benefits, including required copayments and any deductibles, out-of-pockets maximums or coinsurance that are the member’s responsibility.

No balance billing

You may not balance bill our members. You may not collect payment from the member for covered services beyond the member’s copayment, coinsurance, deductible, and for non-covered services unless the member specifically agreed on in writing before receiving the service. In addition, you shall not bill a UnitedHealthcare West member for missed office visit appointments.

Claims status follow-up

We can provide you with an Explanation of Payment (EOP). If you don’t get one, you may follow-up on the status of a claim using one of the following methods:

  • EDI: 276/277 Claim Status Inquiry and Response transactions are available through your vendor or clearinghouse.
  • Online: UnitedHealthcare Provider Portal at > Sign In.
  • Phone: See How to contact UnitedHealthcare West resources section for telephone numbers. This system provides a fax of the claim status detail information that is available.

Claims submission requirements

Mail paper CMS 1500 or UB-04s to the address listed on the member’s ID card. Refer to the Prompt Claims Processing section of Chapter 10: Our claims process, for more information about electronic claims submission and other EDI transactions. If your claim is the financial responsibility of a UnitedHealthcare West delegated entity (e.g., PMG, MSO, Hospital), then bill that entity directly for reimbursement.

Claims submission requirements for reinsurance claims for hospital providers

If covered services fall under the reinsurance provisions set forth in your Agreement with us, follow the terms of the Agreement to make sure:

  • The stipulated threshold has been met.
  • Only covered services are included in the computation of the reinsurance threshold.
  • Only those inpatient services specifically identified under the terms of the reinsurance provision(s) are used to calculate the stipulated threshold rate.
  • Applicable eligible member copayments, coinsurance, and/or deductible amounts are deducted from the reinsurance threshold computation.
  • The stipulated reinsurance conversion reimbursement rate is applied to all subsequent covered services and submitted claims.
  • The reinsurance is applied to the specific, authorized acute care confinement.
  • Claims are submitted in accordance with the required time frame, if any, as set forth in the Agreement. In addition, when submitting hospital claims that have reached the contracted reinsurance provisions and are being billed in accordance with the terms of the Agreement and/or this supplement, you shall:
    • Indicate if a claim meets reinsurance criteria.
    • Make medical records available upon request for all related services identified under the reinsurance provisions (e.g., ER face sheets).

If a submitted hospital claim does not identify the claim as having met the contracted reinsurance criteria, we process the claim at the appropriate rate in the Agreement. An itemized bill is required to compute specific reinsurance calculations and to properly review reinsurance claims for covered services.

Interim bills

We adjudicate interim bills at the per diem rate for each authorized bed day billed on the claim and reconcile the complete charges to the interim payments based on the final bill.

The following process increases efficiencies for both us and the hospital/SNF business offices:

  • 112 Interim – First Claim: Pay contracted per diem for each authorized bed day billed on the claim (lesser of billed or authorized level of care, unless the contract states otherwise).
  • 113 Interim – Continuing Claim: Pay contracted per diem for each authorized bed day billed on the claim (lesser of billed or authorized level of care, unless the contract states otherwise).
  • 114 Interim – Last Claim: Review admits to discharge and apply appropriate contract rates, including per diems, case rates, stop loss/outlier and/or exclusions. The previous payments will be adjusted against the final payable amount.

Reciprocity agreements

You shall cooperate with our participating health care providers and our affiliates and agree to provide services to members enrolled in benefit plans and programs of UnitedHealthcare West affiliates and to assure reciprocity with providing health care services.

If any member who is enrolled in a benefit plan or program of any UnitedHealthcare West affiliate, receives services or treatment from you and/or your sub-contracted health care providers (if applicable), you and/or your subcontracted health care providers (if applicable), agree to bill the UnitedHealthcare West affiliate at billed charges and to accept the compensation provided pursuant to your Agreement, less any applicable copayments and/or deductibles, as payment in full for such services or treatment.

You shall comply with the procedures established by the UnitedHealthcare West affiliate and this Agreement for reimbursement of such services or treatment.


Follow the instructions in the Overpayments section of Chapter 10: Our claims process.


If a member has or develops ESRD while covered under an employer’s group benefit plan, the member must use the benefits of the plan for the first 30 months after becoming eligible for Medicare due to ESRD. After the 30 months elapse, Medicare is the primary payer. However, if the employer group benefit plan coverage were secondary to Medicare when the member developed ESRD, Medicare is the primary payer, and there is no 30-month period.

Medicaid (applies only to MA): Follow the instructions in the Member Financial Responsibility section of Chapter 11: Compensation.

The calendar day we receive a claim is the receipt date, whether in the mail or electronically. The following date stamps may be used to determine date of receipt:

  • Our claims department date stamp
  • Primary payer claim payment/denial date as shown on the Explanation of Payment (EOP)
  • Delegated provider date stamp
  • TPA date stamp
  • Confirmation received date stamp that prints at the top/bottom of the page with the name of the sender

Note: Date stamps from other health benefit plans or insurance companies are not valid received dates for timely filing determination.

Time limits for filing claims

You are required to submit to clean claims for reimbursement no later than 1) 90 days from the date of service, or 2) the time specified in your Agreement, or 3) the time frame specified in the state guidelines, whichever is greatest.

If you do not submit clean claims within these time frames, we reserve the right to deny payment for the claim(s). Claim(s) that are denied for untimely filing may not be billed to a member.

We have claims processing procedures to help ensure timely claims payment to health care providers. We are committed to paying claims for which we are financially responsible within the time frames required by state and federal law.
