20.201—Rule 201. Notice of Disagreement.
A written communication from a claimant or his or her representative expressing dissatisfaction or disagreement with an adjudicative determination by the agency of original jurisdiction and a desire to contest the result will constitute a Notice of Disagreement. While special wording is not required, the Notice of Disagreement must be in terms which can be reasonably construed as disagreement with that determination and a desire for appellate review. If the agency of original jurisdiction gave notice that adjudicative determinations were made on several issues at the same time, the specific determinations with which the claimant disagrees must be identified. For example, if service connection was denied for two disabilities and the claimant wishes to appeal the denial of service connection with respect to only one of the disabilities, the Notice of Disagreement must make that clear.
