Just started coding for pain management and doing the drug screens.

I have been looking around trying to find an answer to my question and hopefully someone can help. I am wondering what the difference between 80346 and 80347 is. I see that it says 1-12 and 13+, but what do the numbers mean?

Thank you
 
".......Drug classes may contain one or more codes based on the number of analytes."

AMA CPT Changes 2015

The Definitive Drug Classes Listing provides the drug classes, their associated CPT codes, and the drugs included in each class. Each category of a drug class, including metabolite(s) if performed (except stereoisomers), is reported once per date of service. Metabolites not listed in the table may be reported using the code for the parent drug. Drug class metabolite(s) is not reported separately unless the metabolite(s) is listed as a separate category in Definitive Drug Classes Listing (eg, heroin metabolite).


Drug classes may contain one or more codes based on the number of analytes. For example, an analysis in which five or more amphetamines and/or amphetamine metabolites would be reported with 80326. The code is based on the number of reported analytes and not the capacity of the analysis.


Definitive drug procedures that are not specified in 80320-80373 should be reported using the unlisted definitive procedure codes 80375, 80376, 80377, unless the specific analyte is listed in the Therapeutic Drug Assays (80150-80203) or Chemistry (82009-84830) sections.

Clinical Example (80346 )


A 58-year-old female with severe fibromyalgia pain is prescribed 20 mg controlled release oxycodone and 0.5 mg clonazepam twice per day and tests positive for opiates using a qualitative, presumptive direct observation dipstick device. The qualitative dipstick device is negative for benzodiazepines. The patient denies any deviation from dosing instructions for both oxycodone and clonazepam. Before the prescription refill is issued, a urine specimen is sent to the laboratory to confirm the clonazepam metabolite is present or if presumptive results are false negative.

Description of Procedure (80346 )


A quantitative, definitive GC/MS analysis for six common benzodiazepines is performed. Any of the instrumental techniques that are defined as definitive may be use. These are high-complexity tests, such as LC-MS/MS or GC/MS. Exact methodology varies by testing facility, but all are instrumental techniques with the ability to specifically identify individual drugs and metabolites, if tested, within a class and rule out interfering drugs and other substances. See descriptions of definitive tests in the Definitive Drug Testing introductory guidelines.



Results indicate the presence of 7-aminoclonazepam, consistent with the use of clonazepam, a benzodiazepine that is not detected using the dipstick device. From these results, the clinician refills the prescription.

See the Definitive Drug Classes Listing on pages [232-234] for a listing of the more common analytes within each drug class



80346 Benzodiazepines; 1-12


80347 13 or more
 
Fifty-eight new definitive drug testing codes (80320-80377, which includes the resequencing of code 83992) arranged by drug classes have been added. Refer to the Definitive Drug Classes Listing table for drugs and metabolites included in each definitive drug class. If applicable, the number of analytes tested has been included in the code descriptor.
 
A laboratory utilizing LCMS to produce quantitative drug test result that is considered a definitive result would report from the definitive codes that were released for 2015 by the AMA. Medicare released HCPCS codes that they want used for certain codes instead which are listed also (G codes).

G6031 Benzodiazepines Assay of benzodiazepines

Since the descriptor describes benzodiazepines in the plural form, it appears only one unit of service would cover 13+ different drugs.
