Surgery & procedures
36415 — Routine venipuncture for collection of specimen
This is one of the most frequently appearing codes on any medical bill — it simply represents a standard blood draw from a vein, usually in the arm.
- Typical setting: Hospital OR, ASC
- National avg charge (illustrative): $3-$15 Medicare allowed (approx. $3-$5 national Medicare average; commercial payers may not reimburse separately when performed in a facility)
- Most-disputed reason: Billing 36415 when it is included in another service: many facilities bundle venipuncture into the facility fee or into other procedures — separate billing can result in duplicate charges
