Is a lead test for my child covered by insurance?
Usually yes, with no cost share, at the ages the schedule calls for. Code 83655 measures how much lead is in your child's blood, from a finger stick in the office or a draw sent out to a lab. Most plans cover the 12 month and 24 month screens as preventive, and Medicaid is required to cover them for children.
Usually
Preventive at 12 and 24 months
12 and 24 months
Those two ages are the screening standard and are required for children on Medicaid. Tests outside those ages need a reason on the claim.
The lab bills too
Send the sample out and the lab bills separately. Families read it as a second charge for the free checkup and call the front desk, not the lab.
Repeats cost
The first screen is preventive. A repeat draw after a high result is diagnostic, and diagnostic labs run through the deductible on most plans.
Before the draw
Deductibles decide whether a sent out lab is free or billed. One eligibility check before the visit shows plan status and deductible left, so the desk warns the family first.

When 83655 is the right code
- Routine screen at 12 months or 24 months
- Any child on Medicaid not tested yet
- Housing or neighborhood risk noted by the office
- A high screen needs a confirming vein draw
- Collection billed on its own separate line
Documentation payers expect
Payers expect a screening diagnosis on a routine test and a lead exposure or abnormal result diagnosis on a repeat. Note whether the sample was a finger stick or a vein draw, since the collection is billed separately.
Why a lead test gets denied
What happens after the lead test
Two more bills can follow one finger stick. The outside lab bills 83655 on its own claim while the office bills the collection, 36416 or 36415, and any handling fee under 99000, which most plans do not pay. A high screen means a confirming vein draw weeks later, and that one is diagnostic, so the deductible applies. Medicaid families pay nothing either way. Knowing plan status and deductible left before the visit is what keeps the second envelope from becoming a phone call.
83655, quick answers
Is the lead test free at the 12 month checkup?
On most plans yes, because it sits on the preventive schedule. A sent out lab can still bill separately if the plan processes that claim as diagnostic.
Why did a lab we never visited send a bill?
The office draws the blood and an outside lab runs it. The lab bills your plan directly, which is why a second statement shows up after a free checkup.
Does Medicaid cover it?
Yes. Blood lead screening at 12 and 24 months is required for children on Medicaid and families pay nothing. A child who missed those ages is tested later, with the cutoff set by the state.
Does Medicare pay for a lead test?
Medicare covers lead testing only when a doctor orders it to work up a symptom or an exposure in an adult. There is no routine screening benefit, since the screening rule is written for children.
What happens if the level comes back high?
The office repeats the test with a vein draw to confirm it, and in most states a high level is reported to the health department. That repeat is billed as diagnostic, which usually means the deductible applies.
