Batch eligibility CSVs now support MBI lookups

You can now run Medicare Beneficiary Identifier (MBI) lookups – with or without a Social Security Number (SSN) – using a CSV batch eligibility check.

Previously, batch eligibility CSVs didn't support some address or SSN fields required for MBI lookups. We've now added several new supported fields to batch eligibility CSVs.

New fields for batch eligibility CSVs

With this update, batch CSVs now support the following fields.

Provider:

• providerReferenceIdentification

Subscriber:

• subscriberSsn

• subscriberGender

• subscriberSuffix

• subscriberAddress1

• subscriberAddress2

• subscriberCity

• subscriberAddressState

• subscriberPostalCode

Dependent:

• dependentMiddleName

• dependentSsn

• dependentGender

• dependentSuffix

• dependentAddress1

• dependentAddress2

• dependentCity

• dependentAddressState

• dependentPostalCode

For more information, see our batch eligibility docs.

Required fields for MBI lookups

With Stedi, you run MBI lookups as eligibility checks with the respective MBILU (MBI Lookup with SSN) or MBILUNOSSN (MBI Lookup without SSN) payer IDs. You can now run these checks using batch eligibility CSVs.

Note: MBI lookups require setup through transaction enrollment. See our related documentation.

MBI lookup with an SSN

To run an MBI lookup with an SSN, you must provide:

• The patient’s first name – subscriberFirstName or dependentFirstName

• The patient’s last name – subscriberLastName or dependentLastName

• The patient’s date of birth  – subscriberDateOfBirth or dependentDateOfBirth

• The patient’s Social Security Number (SSN) – subscriberSsn or dependentSsn

MBI lookup without an SSN

To run an MBI lookup without an SSN, you must provide:

• The patient’s first name – subscriberFirstName or dependentFirstName

• The patient’s last name – subscriberLastName or dependentLastName

• The patient’s date of birth  – subscriberDateOfBirth or dependentDateOfBirth

• The patient’s U.S. state – subscriberAddressState or dependentAddressState

What to include in MBI lookups

In an eligibility check, the patient may be the subscriber or a dependent. Generally, if the dependent has their own member ID, we recommend providing their information as a subscriber.

We don't recommend including more patient demographic information, such as additional address data, than what's required. Doing so can lower MBI lookup success rates.

For more information, see our MBI lookup docs.
