Baughman v. Derwinski — A rating decision may establish service connection, and severance requires 38 C.F.R. § 3.105(d) safeguards

The veteran, Thomas P. Baughman, had long-standing service-connected rheumatic heart disease. In 1986, VA increased his rating after noting that he had ischemic heart disease and that the symptoms related to that ischemic disease would be considered in evaluating the service-connected rheumatic heart disease. After the veteran later developed arteriosclerotic cardiovascular and peripheral vascular disease and underwent an above-the-knee amputation, VA denied service connection for those conditions, and the Board affirmed.

The Court focused on the legal effect of the 1986 rating decision. It held that the rating action, as a matter of law, granted service connection for ischemic heart disease because VA expressly relied on the symptoms of that disease when assigning the increased rating. The Court further held that the Board’s later denial necessarily amounted to an attempted severance of that grant, but VA had not complied with the procedural safeguards or burden of proof required by 38 C.F.R. § 3.105(d). Because service connection had already been established and had not been properly severed, the Board erred in denying the downstream cardiovascular, vascular, and amputation claims. The Court reversed and remanded for further proceedings.

A VA rating decision may, as a matter of law, grant service connection for a condition when it awards benefits based on that condition’s symptoms; once granted, service connection may be severed only under 38 C.F.R. § 3.105(d) with the required procedural protections and clear-and-unmistakable-error showing.

Prior VA rating actions can create binding service-connection grants even without explicit wording. Before denying a related condition, practitioners should ask whether the agency is actually attempting an improper severance without following § 3.105(d).

The decision protects veterans from silent or informal severance by requiring VA to honor the legal effect of its own prior rating actions. It is especially useful where an award decision implicitly recognized a disability as service connected and VA later tries to relabel or deny it without severance procedures.

Treating an already-granted condition as nonservice connected without first severing service connection under 38 C.F.R. § 3.105(d).

VA increases a veteran’s rating because a newly diagnosed disease is part of the service-connected disability picture, then later denies secondary complications from that disease without issuing a formal severance proposal or meeting the clear-and-unmistakable-error standard.

Use this case to argue that favorable rating language or award logic created service connection by operation of law, and that any later contrary determination is invalid absent formal severance procedures under § 3.105(d).
