Code specifying the type of transaction

Usage notes
  • Certain Medicaid programs support additional functionality for Spend Down. Use this code when necessary to further specify the type of transaction to a Medicaid program that supports this functionality.
RT
Spend Down

"Spend Down" is a term used by certain Medicaid programs when a recipient must pay a predetermined amount out of his or her own pocket before full coverage benefits are applied. In order to decrement the amount the recipient must pay out of pocket, a 270 transaction must be sent in with this code.

In the event that the service is not rendered and the Spend Down amount is returned to the recipient, an additional 270 must be sent in with a BHT02 with a code "01" to cancel the Spend Down.

OptionalMax use 2

To specify any or all of a date, a time, or a time period

Usage notes
  • Absence of a Plan date indicates the request is for the date the transaction is processed and the information source is to process the transaction in the same manner as if the processing date was sent.
  • Use this segment to convey the plan date(s) for the subscriber or for the issue date of the subscriber's identification card for the information source.
  • When using code "291" (Plan) at this level, it is implied that these dates apply to all of the Eligibility or Benefit Inquiry (EQ) loops that follow. If there is a need to supply a different Plan date for a specific EQ loop, it must be provided in the DTP segment within the EQ loop and it will only apply to that EQ loop.
  • Required when the information receiver wishes to convey the plan date(s) for the subscriber in relation to the eligibility/benefit inquiry. If not required by this implementation guide, may be sent at the sender's discretion but cannot be required by the information source.

1300
Detail > Information Source Level Loop > Information Receiver Level Loop > Subscriber Level Loop > Subscriber Name Loop > Subscriber Eligibility or Benefit Inquiry Loop > EQ

Subscriber Eligibility or Benefit Inquiry

RequiredMax use 1

To specify inquired eligibility or benefit information

Usage notes
  • When the subscriber is not the patient, the 2110C EQ segment must not be used. When the transaction is used in a batch environment, it is possible to have both 2110C and 2110D EQ segments when the subscriber and dependent(s) are patients whose eligibility or benefits are being verified. See Section 1.4.3 Batch and Real Time for additional information.
  • The 2110C EQ segment begins the 2110C loop.
  • Required when the subscriber is the patient whose eligibility or benefits are being verified. If not required by this implementation guide, do not send.
  • If the EQ segment is used, either EQ01 - Service Type Code or EQ02 - Composite Medical Procedure Identifier must be used. Only EQ01 or EQ02 is to be sent, not both.
    An information source must support a generic request for Eligibility. This is accomplished by submitting a Service Type Code of "30" (Health Benefit Plan Coverage) in EQ01. An information source may support the use of Service Type Codes other than "30" (Health Benefit Plan Coverage) in EQ01 at their discretion.
    An information source may support the use of EQ02 - Composite Medical Procedure Identifier at their discretion. The EQ02 allows for a very specific inquiry, such as one based on a procedure code. Additional information such as diagnosis codes can be supplied in the 2100C HI segment and place of service in the 2110C III segment.
  • If an information source receives a Service Type Code "30" submitted in the 270 EQ01 or a Service Type Code that they do not support, the 2110C EB03 values identified in Section 1.4.7.1 Item #8 must also be returned if they are a covered benefit category at a plan level. Refer to Section 1.4.7 for additional information.
  • EQ01 is a repeating data element that may be repeated up to 99 times. If all of the information that will be used in the 2110C loop is the same with the exception of the Service Type Code used in EQ01, it is more efficient to use the repetition function of EQ01 to send each of the Service Type Codes needed. If an Information Source supports more than Service Type Code "30", and can support requests for multiple Service Type Codes, the repetition use of EQ01 must be supported.
Example
At least one of Service Type Code (EQ-01) or Composite Medical Procedure Identifier (EQ-02) is required

  • Position of data in the repeating data element conveys no significance.
Usage notes
  • An information source must support a generic request for Eligibility. This is accomplished by submitting a Service Type Code of "30" (Health Benefit Plan Coverage) in EQ01.
  • An information source may support the use of Service Type Codes from the list other than "30" (Health Benefit Plan Coverage) in EQ01 at their discretion. If an information source supports codes in addition to "30", the information source may provide a list of the supported codes from the list below to the information receiver. If no list is provided, an information receiver may transmit the most appropriate code.
  • If an inquiry is submitted with a Service Type Code from the list other than "30" and the information source does not support this level of functionality, a generic response will be returned. The generic response will be the same response as if a Service Type Code of "30" (Health Benefit Plan Coverage) was received by the information source. Refer to Section 1.4.7 for additional information.
  • EQ01 is a repeating data element that may be repeated up to 99 times. If all of the information that will be used in the 2110C loop is the same with the exception of the Service Type Code used in EQ01, it is more efficient to use the repetition function of EQ01 to send each of the Service Type Codes needed. If an Information Source supports more than Service Type Code "30", and can support requests for multiple Service Type Codes, the repetition use of EQ01 must be supported.
  • Not used if EQ02 is used.

Use 30 for Health Benefit Coverage or other specific value listed in the Basic Instructions of this document. Only first value is used to determine response.

Dependent Relationship

OptionalMax use 1

To provide benefit information on insured entities

Usage notes
  • Different types of health plans identify patients in different manners;depending upon how their eligibility is structured. However, two;approaches predominate.

The first approach is to assign each member of the family (and plan) a;unique ID number. This number can be used to identify and access;that individual's information independent of whether he or she is a;child, spouse, or the actual subscriber to the plan. The relationship of this individual to the actual subscriber or contract holder would be;one of spouse, child, self, etc.

The second approach is to assign the actual subscriber or contract;holder a unique ID number that is entered into the eligibility system.;Any related spouse, children, or dependents are identified through the;subscriber's ID and have no unique identification number of their;own. In this approach, the subscriber would be identified at the Loop;2100C subscriber or insured level and the actual patient (spouse,;child, etc.) would be identified at the Loop 2100D dependent level;under the subscriber.

  • Required when the information receiver believes it is necessary to identify for an Alternate Search Option supported by the Information Source (See Section 1.4.8) the dependent's relationship to the insured and/or the birth sequence of the dependent in the case of multiple births with the same birth date.

Dependent Eligibility or Benefit Inquiry

RequiredMax use 1

To specify inquired eligibility or benefit information

Usage notes
  • Use this segment to begin the eligibility/benefit inquiry looping structure.
  • If the EQ segment is used, either EQ01 - Service Type Code or EQ02 - Composite Medical Procedure Identifier must be used. Only EQ01 or EQ02 is to be sent, not both.

An information source must support a generic request for Eligibility. This is accomplished by submitting a Service Type Code of "30" (Health Benefit Plan Coverage) in EQ01. An information source may support the use of Service Type Codes other than "30" (Health Benefit Plan Coverage) in EQ01 at their discretion.

An information source may support the use of EQ02 - Composite Medical Procedure Identifier at their discretion. The EQ02 allows for a very specific inquiry, such as one based on a procedure code. Additional information such as diagnosis codes can be supplied in the 2100D HI segment and place of service in the 2110D III segment.

  • If an information source receives a Service Type Code "30" submitted in the 270 EQ01 or a Service Type Code that they do not support, the 2110D EB03 values identified in Section 1.4.7.1 Item #8 must also be returned if they are a covered benefit category at a plan level. Refer to Section 1.4.7 for additional information.
  • EQ01 is a repeating data element that may be repeated up to 99 times. If all of the information that will be used in the 2110D loop is the same with the exception of the Service Type Code used in EQ01, it is more efficient to use the repetition function of EQ01 to send each of the Service Type Codes needed. If an Information Source supports more than Service Type Code "30", and can support requests for multiple Service Type Codes, the repetition use of EQ01 must be supported.
Example
At least one of Service Type Code (EQ-01) or Composite Medical Procedure Identifier (EQ-02) is required

  • Position of data in the repeating data element conveys no significance.
Usage notes
  • An information source must support a generic request for Eligibility. This is accomplished by submitting a Service Type Code of "30" (Health Benefit Plan Coverage) in EQ01.
  • An information source may support the use of Service Type Codes from the list other than "30" (Health Benefit Plan Coverage) in EQ01 at their discretion. If an information source supports codes in addition to "30", the information source may provide a list of the supported codes from the list below to the information receiver. If no list is provided, an information receiver may transmit the most appropriate code.
  • If an inquiry is submitted with a Service Type Code from the list other than "30" and the information source does not support this level of functionality, a generic response will be returned. The generic response will be the same response as if a Service Type Code of "30" (Health Benefit Plan Coverage) was received by the information source. Refer to Section 1.4.7 for additional information.
  • EQ01 is a repeating data element that may be repeated up to 99 times. If all of the information that will be used in the 2110D loop is the same with the exception of the Service Type Code used in EQ01, it is more efficient to use the repetition function of EQ01 to send each of the Service Type Codes needed. If an Information Source supports more than Service Type Code "30", and can support requests for multiple Service Type Codes, the repetition use of EQ01 must be supported.
  • Not used if EQ02 is used.

Use 30 for Health Benefit Coverage or other specific value listed in the Basic Instructions of this document. Only first value is used to determine response.
