For the period beginning on February 17, 2020, entitlement to an evaluation of 40 percent for intervertebral disc syndrome (IVDS) with degenerative arthritis is granted.

Board reasoning

The Board granted a 40 percent rating for IVDS with degenerative arthritis effective February 17, 2020, based on the functional equivalent of favorable ankylosis shown by the February 2020 VA examination and corroborating treatment notes. It remanded the issues of higher ratings prior to February 17, 2020, higher ratings since February 17, 2020, and entitlement to a TDIU for further development and medical opinion, including consideration of medication effects on functional impairment.
