A. Title II

Enter the allowance or denial RBC in Item 22 of the SSA-831

1. Closed Period Cases

  • •

    RBC reflects the period of disability at the time of adjudication.

  • •

    Establish a closed period of disability under Title II, per DI 25510.010

2. Collateral Estoppel

When disability is established before the prior EOD, enter the RBC that reflects the nature of the favorable determination for the earlier period under adjudication. When disability is not established earlier than the EOD for the prior favorable determination or decision, enter RBC “CE” (collateral estoppel - Title II). per DI 27515.001D3.a.

3. Res Judicata

When you deny a claim on the basis of res judicata enter “S1” in Item 22 per DI 27516.005B.3.

4. Childhood Disability Beneficiary (CDB) Re-entitlement Claims

When adjudicating CDB re-entitlement claims, enter the pertinent RBC for the CDB allowance or denial. The RBC should reflect the nature of the allowance or denial on the date of adjudication. Refer to the allowance or denial chart in DI 23505.010B.3. For additional guidance see the following:

  • •

    DI 23505.010A Childhood Disability Beneficiary (CDB) Re-entitlement

  • •

    DI 10115.035A Requirements for Re-entitlement for a change in the re-entitlement period

5. Denials at the time of adjudication

The RBC reflects the nature of the allowance or denial at the time of adjudication. However, in denials, when a technical requirement is no longer met,

  • •

    Use the RBC at the time the technical requirement was last met;

  • •

    Select the appropriate code from the reference charts in DI 26510.045C, in this section.

a. Impairment meets listings

Description of Basis for Decision

Type of Claim

Reg. Basis Code1

The individual is disabled on medical considerations alone because the disability is caused by an impairment specifically listed in the "Listing of Impairments" and the medical evidence contains the specific findings listed for the impairment. This entry will also include cases of “statutory blindness.”

No allowance should be coded as meeting the listings unless the specific medical criteria of one or more of the listed impairments are met, as shown by the medical evidence in file.

Description of Basis for Decision Type of Claim

Reg. Basis Code1

The individual is disabled on medical considerations alone (or for DCs under 18, functional considerations as well) because of an impairment or a combination of impairments of severity equal to the level of severity contemplated in the "Listing of Impairments," but where all the specific requirements of the Listing are not met on the basis of the medical evidence in file.

No allowance should be coded as equaling the listings on the basis of medical evidence which is inadequate to describe impairment severity; the medical evidence should be adequate albeit somewhat different from the specific listing requirements.

1 The numerical codes "1," "3," "5" and "7" (e.g., "A1" or "E3") signify that the earnings requirement (in DIB cases) or the prescribed period requirement (in DWB and CDB re-entitlement cases) is not at issue. The numerical codes "2," "4," "6" and "8" indicate that in addition to the basis for the disability determination, the earnings requirement, prescribed period requirement, or re-entitlement period requirement expired before the date of the current decision; e.g., claimant is not disabled through the date the earnings requirement was last met.

2 These codes are used to differentiate between an impairment that prevents SGA at time of adjudication but is not expected to prevent SGA for 12 months as opposed to an impairment that no longer prevented SGA at time of adjudication and did not prevent SGA for 12 months.

3 Do not use M6 when the claimant cooperated but there is insufficient evidence of a disability relating to the period before the insured status or prescribed period requirement was last met. In these situations, use F2.

4 These codes are used to differentiate between an impairment that results in marked and severe functional limitations at time of adjudication but is not expected to do so for 12 months (N35, N46), as opposed to an impairment that no longer causes marked and severe functional limitations at time of adjudication and did not do so for 12 months (N34, N45).

5 Also use this code along with the appropriate DAA indicator when DAA is material to the determination of disability.
