I am going through the same problem. My initial filing for Diabetes was back in 2007, denied, appeal, remand [3 times] then VBA finally obtained their own IMO. Their [VBA] IMO agreed with my IMO [Dr. Bash] and was finally granted in 2014. Was rated at 20%, filed a NOD immediately, and was granted 40%, but with an effective date of the NOD!?!?!?!? Filed Form 9 Appeal back in May 2015 which is still pending. I requested a face to face with DRO before Appeal goes to BVA. Heard nothing.
Anyway, here are a few references:
Title 38 → Chapter I → Part 3 → Subpart A → §3.156
§3.156 New and material evidence.
(b) Pending claim. New and material evidence received prior to the expiration of the appeal period, or prior to the appellate decision if a timely appeal has been filed (including evidence received prior to an appellate decision and referred to the agency of original jurisdiction by the Board of Veterans Appeals without consideration in that decision in accordance with the provisions of §20.1304(b)(1) of this chapter), will be considered as having been filed in connection with the claim which was pending at the beginning of the appeal period. (Authority: 38 U.S.C. 501)
38 CFR Effective Dates §3.400 General.
Except as otherwise provided, the effective date of an evaluation and award of pension, compensation or dependency and indemnity compensation based on an original claim, a claim reopened after final disallowance, or a claim for increase will be the date of receipt of the claim or the date entitlement arose, whichever is the later. (Authority: 38 U.S.C. 5110(a))
(h) Difference of opinion (§3.105).

In Fenderson v. West, 12 Vet. App 119 (1999), the Court emphasized the distinction between a new claim for an increased evaluation of a service-connected disability and a case (such as this one) in which the Veteran expresses dissatisfaction with the assign- ment of an initial disability evaluation where the disability in question has just been recognized as service-connected. VA must assess the level of disability from the date of initial application for service connection and determine whether the level of disability warrants the assignment of different disability ratings at
different times over the life of the claim-a practice known as "staged rating."
