What 82785 covers
This laboratory assay measures the concentration of total immunoglobulin E (IgE), an immune protein associated with allergic responses. Clinicians commonly order it as part of an evaluation for suspected allergic disease. Unlike allergen-specific IgE testing, the result is not tied to a particular allergen. A clinical laboratory performs the assay, generally using serum, on a clinician's order.
Report 82785 for a total IgE assay, not once per allergen. Allergen-specific IgE testing is reported separately when performed. Medicare pays 82785 through the Clinical Laboratory Fee Schedule (CLFS), not the physician fee schedule. The 2026 national CLFS amount is $16.46, unchanged from 2020 through 2026. The same national amount applies in every state and locality, without a geographic adjustment or office/facility difference.

How Medicare pays 82785
Clinical lab tests aren’t priced like physician services. They’re paid from their own fee schedule, with its own rules. See the whole lab fee schedule.
One national amount
CMS sets a single Clinical Laboratory Fee Schedule amount for 82785. There’s no geographic (GPCI) adjustment, so it pays the same in every state and payment locality.
No office or facility rate
Lab tests aren’t built from relative value units, so there’s no office and facility split: the place of service doesn’t change the CLFS amount.
Updated every quarter
CMS republishes the CLFS each quarter. New tests, often proprietary laboratory analyses (PLA codes), join during the year; existing amounts are updated each January.
Excluded from the physician fee schedule
The physician fee schedule lists 82785 with status X (excluded by statute), so the test itself is paid only from the CLFS.

82785 billing questions
How does 82785 differ from allergen-specific IgE testing?
82785 measures total IgE in the specimen. Allergen-specific IgE testing, such as 86003, evaluates reactivity to particular allergens.
Can total IgE and allergen-specific IgE be reported together?
They measure different things and may both be ordered during an allergy evaluation. Report each test performed under its applicable code.
Is 82785 reported once for each allergen tested?
No. 82785 represents the total IgE assay, not a separate result for each suspected allergen.
How does Medicare pay for 82785?
Medicare pays 82785 under the CLFS at one national amount, without locality or office/facility variation. It is paid only through the CLFS.
Should 82785 be selected for an IgG subclass assay?
No. 82785 measures IgE; use the applicable IgG subclass code when the laboratory measures an IgG subclass.
