CPT® Code 36415

Blood collection by venipuncture

CPT® Code 36415 is used to report the collection of blood specimens by venipuncture. This code applies when a healthcare provider collects a blood sample from a patient through a venipuncture, which is the process of drawing blood from a vein, typically for diagnostic testing or other medical purposes.

When to use CPT® Code 36415

This code is appropriate when:

  • A blood specimen is collected by venipuncture.
  • The collection is done for diagnostic testing, screening, or lab analysis, such as in situations where the patient needs lab tests or a blood panel.
  • The procedure does not involve more complex blood draws like arterial puncture or apheresis.
  • The blood is being collected for routine purposes (e.g., routine check-ups or monitoring) or when specific tests are required as part of the medical treatment plan.

Common reasons for using this code include:

  • Routine blood draws for laboratory work.
  • Blood collection for glucose monitoring, cholesterol tests, or other diagnostic panels.
  • Specimen collection for a variety of medical conditions, including monitoring chronic diseases or performing screenings.

Administration and time requirements

CPT 36415 generally does not have specific time requirements but should be documented as part of the encounter. The provider is responsible for ensuring that all aspects of the blood collection are properly documented, including:

  • The site of collection (such as the antecubital fossa or hand).
  • The specific vein used for venipuncture (if relevant).
  • The reason for the blood draw, if applicable.
  • The method of collection (venipuncture).

In many cases, if additional services such as blood processing or handling are involved, other codes might need to be used alongside 36415 to reflect those procedures.

Key documentation tips

  • Document the reason for the blood collection, such as the tests or diagnostic evaluations the blood is being collected for.
  • Specify the site of venipuncture (e.g., the arm or hand) and whether any special techniques or tools were used (e.g., butterfly needle, standard vacutainer).
  • Include any complications or difficulties that occurred during the blood draw, such as issues with the vein or patient reactions.
  • If the blood specimen is for a specific test (e.g., CBC, lipid panel), document this information for clarity in the medical record.
