CPT 36415: Billing the Blood Draw
CPT 36415 is the code for drawing blood from a vein. Medicare pays it from the lab fee schedule, at $9.34 for 2026, and only under conditions written into the regulation in 2023. This guide covers what the code pays, when a draw qualifies, the one-fee-per-visit rule, how it sits beside the tests on a claim, and the denials that follow from getting it wrong. Every rule was read from CMS and the eCFR on 23 October 2026.

What 36415 covers
CPT 36415 is the code for drawing blood from a vein with a needle: venipuncture to collect a blood sample. CMS calls it the specimen collection fee, a nominal payment "to cover the appropriate costs in collecting the sample" for a clinical diagnostic laboratory test, "which could include the costs related to drawing, collecting, or handling a specimen" (Ch. 16 § 60.1). It is paid from the Clinical Laboratory Fee Schedule, not the physician fee schedule, and sits beside three related codes:
| Code | What it covers, in plain words | 2026 rate |
|---|---|---|
| 36415 | Venipuncture to collect a blood sample | $9.34 |
| G0471 | Venipuncture or catheter urine collection for a skilled nursing facility patient, or by a lab on behalf of a home health agency | $11.34 |
| P9612 | Urine specimen collected by catheter, one patient | $9.34 |
| P9615 | Urine specimen collected by catheter, several patients | $9.34 |
CMS fee file 26CLABQ4 (CY 2026, quarter 4), read 2026-10-23. Rates as the file lists them for CY 2026.
A fingerstick is not on the list. The manual says the fee is not payable for specimens whose collection cost is minimal, "such as a throat culture or a routine capillary puncture for clotting or bleeding time", and the 2026 fee file has no line for capillary collection at all.
The rate moves every January. It sat at $3 for years (CY 2023 PFS final rule), and that rule set it at $8.57 from January 1, 2023 (§ 414.523(a)(1)), and since 2024 it rises each year by the CPI-U for the 12 months ending the previous June 30. That is how it reached $9.34 for 2026.
When 36415 is billable
Since 2023 the conditions sit in regulation as well as the manual. The specimen must be used for a lab test paid under the Clinical Laboratory Fee Schedule, it must be blood drawn by venipuncture or urine collected by catheter, and it must be collected by a trained technician (a phrase that, the manual says, "includes a phlebotomist") from a patient described this way:
Collected by a trained technician from a Medicare beneficiary who is—(A) Homebound as described in 42 CFR 424.22(a)(1)(ii). (B) A non-hospital inpatient, but only when no qualified personnel are available at the facility to collect the specimen;
CMS's March 2026 fact sheet says the same in plain words: it pays specimen collection fees "when medically necessary for a lab technician to draw a specimen from either a nursing home or homebound patient" (MLN006818). An independent lab that draws in those settings annotates the claim, for example "patient homebound" or "patient in nursing home, no qualified person on duty to draw specimen", and bills the fee "in conjunction with a covered laboratory test" (§ 60.1.1).
The routine draw in a physician office or patient service center
The 2023 rule that wrote these conditions into § 414.523 left out the manual's old section on physicians billing the fee, and today's manual no longer has it. CMS noted that office-based practitioners filed 31.1 percent of all specimen collection claims in 2019 and that physician fee schedule codes exist for physician draws (87 FR 69745). Neither the rule text nor the manual describes the everyday office draw on its own terms. Before you count on 36415 for in-office Medicare draws, read your MAC's lab billing guidance or ask the MAC in writing. Commercial payers set their own rules.
Takeaway
The collection-fee rules
Seven rules from Ch. 16 § 60 decide how many fees a visit earns and who earns them (Claims Processing Manual):
| Rule | What it means at the draw station | Where |
|---|---|---|
| One fee per encounter | Two tubes or ten, blood and catheter urine together: one collection fee for the visit. | § 60.1 |
| A series is one encounter | The draws of a glucose tolerance test count as a single encounter. | § 60.1 |
| Two specimen types only | Blood by venipuncture or urine by catheter. Not a throat swab, not a routine fingerstick. | § 60.1 |
| The one who drew it bills it | The fee “will not be paid to anyone who has not extracted the specimen”; no handling charge when one lab refers a specimen to another. | §§ 60.1, 60.1.1 |
| No patient cost sharing | Neither the deductible nor the 20% coinsurance applies to the collection fee. | § 60.1.2 |
| Updated every January | By the CPI-U for the 12 months ending June 30 of the year before. | § 60.1 |
| Travel follows the fee | A travel allowance is paid only when the collection fee is paid: flat rate up to 20 eligible miles, per mile beyond that or across several stops. | § 60.2; § 414.523(a)(2) |
The travel allowance has its own formula in § 414.523(a)(2): the IRS standard mileage rate plus the latest median hourly wage for phlebotomists from the Bureau of Labor Statistics, divided by 40 to stand for an average driving speed. On the flat-rate basis that mileage rate is multiplied by ten and split across the Medicare patients drawn on the trip.
Billing it with the tests
36415 never stands alone on a Medicare claim: the draw must feed a lab test paid under the fee schedule. Seven situations every draw station meets, and what the rules in Ch. 16 § 60 put on the claim:
| Situation | What goes on the claim |
|---|---|
| A lab's phlebotomist draws a homebound patient; the lab runs a metabolic panel | The test code, 36415, the travel allowance, and the annotation “patient homebound” |
| The lab draws a nursing facility resident with no qualified staff on duty | The test code and G0471, not 36415 |
| Two tubes at one visit, one for a metabolic panel and one for a blood count | Both test codes and one collection fee |
| A three-draw glucose tolerance test | One encounter, one collection fee |
| A fingerstick A1c run in the office | The test code only: capillary collection earns no fee |
| A reference lab receives a tube drawn elsewhere | The test code only: no collection fee, no handling charge |
| An office draws and sends the tube to a reference lab | At most 36415 from the office, if your MAC pays office draws |
The diagnosis on the lab line comes from the ordering clinician. The manual: "a laboratory or other provider may not report on a claim for Medicare payment a diagnosis code in the absence of physician-supplied diagnostic information supporting such code" (Ch. 16 § 120.1). If the office also runs tests on the blood it draws, it is a lab under CLIA and needs a certificate (the CLIA certificate finder names which, and how to get a CLIA certificate covers the steps); waived tests there also need the QW modifier on the right codes.
Common 36415 denials
- A second collection fee in one encounter. "Only one collection fee is allowed for each type of specimen for each patient encounter, regardless of the number of specimens drawn" (§ 60.1). Bill one unit. CMS's Medically Unlikely Edits exist "to prevent improper payments when services are reported with incorrect units of service" (CMS NCCI); check the current MUE table for the limit your claim type gets.
- No covered lab test behind it. The fee is paid for a specimen "used to perform a CDLT paid under the CLFS", and § 60.1.1 has it billed "in conjunction with a covered laboratory test". Put the draw on the same claim as the test it was drawn for.
- Billed by a lab that did not draw. The reference lab that only receives the tube has no collection fee to bill.
- A fingerstick coded as venipuncture. Capillary collection earns no fee; coding it as 36415 is a coding error, not a missed charge.
- No annotation on an outside draw. MACs check the homebound or nursing-home annotation "through scientific claims samples as well as through regular bill review techniques" (§ 60.1.1).
- A test likely to be denied, drawn without an ABN. When the lab test may not be covered, the Advance Beneficiary Notice decides who pays. "The billing entity will always be held responsible for effective delivery regardless of who gives the notice" (Ch. 30 § 50.3).
A denial you disagree with goes to redetermination "within 120 calendar days from the date a party receives the notice of the initial determination" (§ 405.942(a)).
Takeaway
Who catches it before the claim goes out
A billing system can enforce the one-fee rule and the capillary rule; it cannot know your MAC's position on office draws unless someone loads it. Compare what vendors document in lab billing software compared and XiFin vs TELCOR, or what an outside firm takes on in lab billing companies compared. For where the $9.34 comes from and how lab rates are set, read the Clinical Laboratory Fee Schedule and PAMA.
