The appellant also seeks direct payment from the Secretary of 20% of the award of the TDIU benefits granted the veteran. Eligibility for TDIU is a rating question dependent on a grant of service connection. See 38 C.F.R. § 4.16.

Therefore, while a claim for service connection of a disability always raises the issue of degree of disability, the issue of TDIU must be reasonably raised based on the submissions of the claimant or the evidence of record.
