Is the anemia finger stick at a checkup covered?
Usually yes, free, at the 12 month checkup. Code 85018 is the hemoglobin number, the quick finger stick that shows whether the blood is carrying enough iron. Plans treat the one at 12 months as preventive screening. A repeat months later to watch a known low number is diagnostic and can land on the deductible.
Free once
Preventive at the 12 month visit
12 months
One screen at 12 months is the standard, and that is the one plans pay as preventive. Extra screens at other ages need a reason.
Second one costs
Rechecking a low hemoglobin three months later is diagnostic, not screening. Same finger stick, same code, different diagnosis, and the deductible now applies.
85025 is bigger
A full blood count is a different code and a bigger bill. If the doctor wants the whole panel, bill 85025 and expect deductible questions.
One check first
Screening or diagnostic changes who pays. One eligibility check before the visit shows plan status and deductible left, so the desk can say it plainly.

When 85018 is the right code
- Routine anemia screen at the 12 month visit
- Only the hemoglobin number is needed
- Run in the office off a finger stick
- Follow up on a known low result
- Not part of a full blood count that day
Documentation payers expect
Payers expect a screening diagnosis on the routine test and a symptom or prior abnormal result on a recheck. Note the method used, and never bill it alongside a complete blood count from the same draw.
85018 or its neighbors?
- 85018
- Hemoglobin only, usually a finger stick
- 85025
- Full blood count with the differential
- 85014
- Hematocrit, the packed cell number
- 36416
- The finger stick collection fee
Picking the wrong neighbor is its own denial category. The chart decides, not the schedule.
Why the anemia check gets denied
What happens after a low result
A low hemoglobin usually leads to a recheck in a few months and often a fuller workup, 85025 for the full count plus iron studies such as 83540 and 82728, run by an outside lab that bills on its own claim. Those are diagnostic, so the family pays until the deductible is met, and a specialist referral can need prior authorization. Knowing plan status and deductible left before the visit turns that from a surprise into a plan.
85018, quick answers
Is the finger stick free at the 12 month visit?
On most plans yes. The 12 month anemia screen sits on the preventive list, so it is covered with no copay when the claim carries a screening diagnosis.
Why was the same test free last year and billed this year?
Because the reason changed. A routine screen is preventive. A recheck of a known low number is diagnostic, and diagnostic labs run through the deductible.
Is this the same as a full blood count?
No. 85018 is only the hemoglobin number. A complete blood count is 85025, includes far more, and is priced and processed differently.
Does Medicare cover it?
Medicare pays for a hemoglobin when a doctor orders it to check a symptom or follow a condition, not as a routine screen. There is no preventive anemia screening benefit for adults.
Can the office run it while we wait?
Yes, most pediatric offices run it in the room and have the number in minutes. That is why the practice bills it instead of an outside lab.
