• CPT code 80100 – Drug screen, qualitative; multiple drug classes chromatographic method, each procedure;
• CPT code 80101 – Drug screen, qualitative; single drug class method (e.g., immunoassay, enzyme assay), each drug class;
• CPT code 80101QW – Drug screen, qualitative; single drug class method (e.g., immunoassay, enzyme assay), each drug class;
• G0430 – Drug screen, qualitative; multiple drug classes other than chromatographic method, each procedure;
• G0430QW – Drug screen, qualitative; multiple drug classes other than chromatographic method, each procedure;
• G0431 – Drug screen, qualitative; single drug class method (e.g., immunoassay, enzyme assay), each drug class; and
• G0431QW – Drug screen, qualitative; single drug class method (e.g., immunoassay, enzyme assay), each drug class.

It looks like instead of 80101 you need the G code for Medicare, see this:

• For purposes of the CLFS (Clinical Laboratory Fee Schedule), beginning with dates of service on or after April 1, 2010, when performing a qualitative drug screening test for multiple drug classes that uses chromatographic methods, CPT code 80100 is the appropriate code to bill.
• New test code G0430 was created to limit the billing to one time per procedure and to remove the limitation of the method (chromatographic) when this method is not being used in the performance of the test.
• As a result, when a clinical laboratory that does not require a CLIA certificate of waiver performs a qualitative drug screening test for multiple drug classes that does not use chromatographic methods, new test code G0430 is the appropriate code to bill.
• When a clinical laboratory that does require a CLIA certificate of waiver performs a qualitative drug screening test for multiple drug classes that does not use chromatographic methods, new test code G0430QW is the appropriate code to bill.

What to Remember
• New test code G0431 is a direct replacement for CPT code 80101.
• For purposes of the CLFS, effective with dates of service on or after April 1, 2010, new test code G0431 should be utilized by those clinical laboratories that do not require a CLIA certificate of waiver.
• Those clinical laboratories that do require a CLIA certificate of waiver should utilize new test code G0431QW.
• Effective April 1, 2010, CPT code 80101 will no longer be covered by Medicare, and CPT code 80101QW will be deleted.

For 82947/82948 - I tried to find information to see if anything had changed for 2010. My information is a bit "iffy"... if you don't have a subscription to a service that provides current CPT codes and changes throughout the year, you should consider it. I don't work in a specialty that uses lab codes, so I don't have a subscription.

Read the description in your book. "Reagent method" means a drop of blood is placed on a strip, blotted at the appropriate time interval, then compared to a color chart on the side of the bottle.

The last info I can find is that 82962 is the blood glucose test code by blood glucose meter.
