Start with the evidence question
A Fully Developed Claim, or FDC, is an optional way to submit a disability compensation claim with supporting evidence up front. It is a processing route, not a promise of approval or a particular rating.
Evidence requirements depend on the claim. VA may need service and medical records, and may also consider statements based on firsthand observations. Read the evidence requirements for the issue you are claiming.
Know what fully developed means
For an FDC, submit VA Form 21-526EZ with the evidence you have and certify that no more evidence is needed. Include relevant private medical records and any related service records in your possession. Identify related federal records VA can request. Attend any exam VA schedules.
If you later submit additional evidence, or VA needs other non-federal records, VA can move the claim into standard processing. Keep providing needed evidence rather than withholding it to stay in a processing program.
Compare standard processing
A standard disability claim gives VA more responsibility for gathering evidence. Identify relevant records and provide the information and permissions VA requests. VA can obtain relevant federal records and make reasonable efforts to request authorized private records.
You remain responsible for making sure VA receives requested records from non-federal sources. If a provider cannot or will not supply them, VA may ask you to help obtain them. VA does not pay private-source record fees or postage.
Prepare a useful record list
As a practical organizing step, list the providers or facilities, approximate treatment dates, and records already obtained. Keep copies of what you submit and any confirmations. Organization can help you see what is missing; it does not establish service connection by itself.
Both routes require evidence supporting the benefit sought. No specific decision date or result is guaranteed.
