Does an economics degree qualify for the 17 month OPT extension? (This question is about US work authorization for foreign students.)

The list of STEM fields which will permit one to get a 17 month OPT extension include only two fields that containing the word "economics".


45.0603 Econometrics and Quantitative Economics
51.2007 Pharmacoeconomics/Pharmaceutical Economics


The latter is definitely not applicable to me, so I am interested only in the former.

According to this page, "45.0603 Econometrics and Quantitative Economics" is defined to be


  A program that focuses on the systematic study of mathematical and statistical analysis of economic phenomena and problems. Includes instruction in economic statistics, optimization theory, cost/benefit analysis, price theory, economic modeling, and economic forecasting and evaluation.


My question is: If my diploma says simply that I have a degree in economics (as is often the case with degrees in economics), would I automatically qualify for the 17 month OPT extension? If not, is there any way I could go about proving that I satisfy the above definition? (It seems to me that any decent degree in economics would arguably satisfy the above definition.)
CIP codes in economics include:

45.0601) Economics, General.

45.0602) Applied Economics.

45.0603) Econometrics and Quantitative Economics.

45.0604) Development Economics and International Development.

45.0605) International Economics.

45.0699) Economics, Other.

Your registrar's office should be able to tell you what the CIP code is for the degree program that you're in.  I would expect the list that you have referenced to include other codes if they were approved for OPT.
