Appeal type: Lab
Decision: Favorable

 
We decided that the Plan has to pay for drug testing services (CPT 80307 and HCPCS G0483) provided to the 
enrollee on August 12, 2019. 
 
You asked the Plan to pay for the services. You say that this should be paid for. The Plan denied your request. 
The Plan says that the documentation submitted did not include a valid physician order/lab requisition or 
medical records (signed by the ordering physician); therefore, the billed codes cannot be verified. 
 
The Plan must follow Medicare rules. Medicare rules say that providers must report services correctly. 
Providers must report services with the appropriate CPT code.  
 
In this case, the CPT Code Manual definition of the denied codes is: 
 
CPT 80307: 
 
Drug test(s), presumptive, any number of drug classes, qualitative; any number of devices or procedures, by 
instrument chemistry and analyzers (e.g.,  utilizing immunoassay [EIA, ELISA, EMIT, FPIA, IA, KIMS, 
RIA]), chromatography (e.g., GC, HPLC), and mass spectrometry either with or without chromatography, 
(DAT, DESI, GC-MS, GC-MS/MS, LC-MS, LC-MS/MS, LDTD, MALDI, TOF) includes sample validation 
when performed, per date of service 
 
HCPCS G0483: 
 
Drug test(s), definitive, utilizing (1) drug identification methods able to identify individual drugs and 
distinguish between structural isomers (but not necessarily stereoisomers), including, but not limited to gc/ms 
(any type, single or tandem) and lc/ms (any type, single or tandem and excluding immunoassays (e.g., ia, eia, 
elisa, emit, fpia) and enzymatic methods (e.g., alcohol dehydrogenase)), (2) stable isotope or other universally 
recognized internal standards in all samples (e.g., to control for matrix effects, interferences and variations in 
signal strength), and (3) method or drug-specific calibration and matrix-matched quality control material (e.g., 
to control for instrument variations and mass spectral drift); qualitative or quantitative, all sources, includes 
specimen validity testing, per day; 22 or more drug class(es), including metabolite(s) if performed 
 
We asked our physician reviewer to carefully review the case file and apply the relevant Medicare rules to 
determine if the Plan was correct in denying the request to pay for the services. Our reviewers say that the 
services at issue in this case were supported by the medical records. Our physician reviewer found the 
laboratory submitted a valid/signed physician laboratory requisition form and lab results. The review has 
determined that the records support the denied codes. The records support that 22 or more drug classes were 
tested. 
 
We looked at this physician's review, the file, and Medicare rules. Based on this information, we decided that 
Medicare rules for coverage of the services have been met. Therefore, we decided that the Plan has to pay for 
drug testing services (CPT 80307 and HCPCS G0483) provided to the enrollee on August 12, 2019.  
 
If the Plan does not agree with our decision, they can ask us to open a case again. We only open a case again 
if we believe there was a mistake or if there is new information to review. The Plan has to show us the mistake 
and/or send us the new information. This does not happen often. If we decide to open the case again, we will 
send you a letter.
