The Veteran's appeal is remanded due to the need for a VA examination to clarify whether her lichen simplex chronicus covers at least 20 percent of her entire body surface and if she requires systemic therapy such as corticosteroids or other immunosuppressive drugs for at least six weeks during a twelve-month period.

The Veteran's PTSD is rated at 70 percent, which does not meet the criteria for a higher rating.,A 10 percent disability rating for an epidermal cyst prior to April 23, 2019 has been granted.,A disability rating in excess of 10 percent for residual status post epidermal cyst excision scar is denied.,The Veteran's lichen simplex chronicus was rated as noncompensable before October 15, 2020 and at 10 percent thereafter. The claim for a higher rating remains pending.,TDIU has been denied based on the evidence not showing total occupational and social impairment due to service-connected disabilities.,Left shoulder degenerative arthritis with impingement syndrome and partial rotator cuff tear is rated at 20 percent, which does not meet the criteria for a higher rating.,Left knee degenerative arthritis remains rated at 10 percent.

The Board has dismissed the claims for service connection for diabetes and Lichen Simplex Chronicus, as well as the claim for a total disability rating based on individual unemployability due to service-connected disabilities because the Veteran died during the appeal process.

The Board has determined that additional examinations are needed for the Veteran's PTSD, left shoulder disability, left knee degenerative arthritis, epidermal cyst, and lichen simplex chronicus due to potential worsening of symptoms. The issues of entitlement to increased ratings for these conditions have been remanded.

The Board denied service connection for bilateral hearing loss but granted a 10 percent rating for lichen simplex chronicus. The decision is mixed as it addressed both issues.
