What 86720 covers
Code 86720 identifies laboratory analysis for antibodies directed against Leptospira, the organism that causes leptospirosis. Clinicians may order the test when compatible illness follows exposure to animal urine or water or soil contaminated by infected animals. The laboratory reports the antibody analysis, and clinicians interpret the result with the patient's presentation and exposure history. This is organism-specific serology, not a general infectious-disease antibody panel.
Report 86720 for the Leptospira antibody analysis. Medicare pays it through the CLFS at one national amount in every state and locality, without an office-versus-facility difference. The 2026 national CLFS amount is $16.20, unchanged since 2020. Payment is from the CLFS only, rather than the physician fee schedule.

How Medicare pays 86720
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 86720. 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 86720 with status X (excluded by statute), so the test itself is paid only from the CLFS.

- 86717 is for Leishmania antibody testing, not Leptospira. These codes identify antibody analyses for different pathogens.
- 86723Listeria antibody$13.19

86720 billing questions
When should a claim use 86720 rather than another infectious-disease antibody code?
Use 86720 when the laboratory analyzes antibodies to Leptospira. Select a different organism-specific code when the ordered test targets another pathogen, such as Legionella or Leishmania.
Does this code report a Leptospira antibody result or a broader antibody panel?
It identifies analysis for antibodies to Leptospira, not a general infectious-disease antibody panel.
When may a clinician order Leptospira antibody testing?
It may be ordered when compatible illness and exposure history raise concern for leptospirosis.
How does Medicare pay for 86720?
Medicare pays it through the CLFS at one national amount that applies in every locality, with no office or facility difference. Payment is from the CLFS only.
