20 CFR 320.8 - Notice of initial determination.
(a) Benefits payable. If benefits are payable for a claim, no special notice of the award will be issued to the claimant. A notice of the award will be sent to the base-year employer(s). The amount of benefits due will be certified to the United States Treasury Department for payment.
(b) Benefits not payable. If an initial determination results in denial of a claim, either in whole or in part, the adjudicating office shall issue a notice of the denial within 15 days of the date that it makes its determination. The notice shall explain the basis for the denial of benefits and shall set forth what steps the claimant can take to contest the denial.
(c) Communication of notice of denial. When the adjudicating office mails the denial notice to the claimant's address of record, it shall be considered that notice of the denial has been communicated to the claimant on the date of mailing such notice. If the adjudicating office has been notified that a claimant has an attorney or other representative helping him or her with the claim, a copy of the denial notice shall be sent to the attorney or such other representative.
