alkaloids definitive drug screening

CPT 80300, CPT 80301, CPT 80302, CPT 80303 & CPT 80304 (Drug Testing)

The AMA introduced the following pathology/laboratory code changes for 2015.

The three subsections associated with drug procedures are:

  • Drug Assay,
  • Therapeutic Drug Assay (TDA), and
  • Chemistry

In the “Drug Assay” section, the two following subsections are the major categories for drug testing:

  • Presumptive Drug Class and
  • Definitive Drug Class testing

These types of drug testing are commonly done first by presumptive screening method then may be done by a definitive drug identification method as well.

CPT Codes For Drug Testing

The following CPT codes can be used for Drug Testing. CPT Code 80300, CPT Code 80301, CPT Code 80302, CPT Code 80303 & CPT Code 80304.

CPT Code 80300

Description of CPT 80300: Drug screen, any number of drug classes from Drug Class List A; any number of non-TLC devices or procedures, (eg, immunoassay) capable of being read by direct optical observation, including instrumented-assisted when performed (eg, dipsticks, cups, cards, cartridges), per date of service.

CPT Code 80301

Description of CPT 80301: Drug screen, any number of drug classes from Drug Class List A; single drug class method, by instrumented test systems (eg, discrete multichannel chemistry analyzers utilizing immunoassay or enzyme assay), per date of service.

CPT Code 80302

Description of CPT 80302: Drug screen, presumptive, single drug class from Drug Class List B, by immunoassay (eg,ELISA) or non-TLC chromatography without mass spectrometry (eg, GC, HPLC), each procedure

CPT Code 80303

Description of CPT 80303: Drug screen, any number of drug classes, presumptive, single or multiple drug class method; thin layer chromatography procedures(s) (TLC) (eg, acid, neutral, alkaloid plate), per date of service

CPT Code 80304

Description of CPT 80304: Drug screen, any number of drug classes, presumptive, single or multiple drug class method; not otherwise specified presumptive procedure (eg, TOF, MALDI, LDTD, DESI, DART), each procedure

Coding Guidelines For Drug Testing

A key point for Presumptive Drug testing is that the reported value may be qualitative, semi-quantitative or quantitative depending on the purpose of the testing.

AMA specifically states that methods that cannot distinguish between structural isomers (such as morphine and hydromorphone or methamphetamine and phentermine) are considered presumptive.

The list of drug classes and the methodology used are considered when coding presumptive procedures.

AMA provides a complete list of drugs categories as “Drug Class A” or “Drug Class B” in the code book, located in the “Presumptive Drug Class Screening” section.
