Bloodworks Northwest Laboratories

Please contact the specific laboratories if you would like more information regarding any of our policies or services.

It depends. In general it is best to ship samples Monday – Thursday so the lab receives before Friday. Aside from the Immunoheatology Reference Lab and Transfusion Services, laboratories are officially closed on Saturday, Sundays and nationally observed holidays (listed below). Testing will not be done on those days.

There is potential for samples to be stored over the weekend for next business day testing. If a Friday through Sunday draw is unavoidable please refer to the Testing Index and look up the test you are ordering. Scroll down to the sample information and shipping information sections for that specific test to read about any restrictions there may be when drawing the sample. Contact the specific lab below if you have any further questions about when to draw to the sample and whether or not it can be drawn over the weekend.

Nationally observed holidays:

• Martin Luther King Day
• President’s Day
• Memorial Day
• Independence Day
• Labor Day
• Veterans Day
• Thanksgiving Day
• Christmas Day
• New Years Day

Interim reports are received when critical test values are needed before either all testing is complete or before a director has signed off the final report. Interim reports are also available upon request. Interpretation of results will be included only in the final report. These interim reports are provided by all laboratories except Transfusion Services.

It is your responsibility to determine the correct CPT codes to use for billing. While our online test catalogue lists CPT codes to provide some guidance, the CPT codes listed only reflect our interpretation of the CPT codes appropriate for our tests and are not necessarily correct.

In some cases, a profile of tests may provide a comprehensive list of CPT codes for all potential tests included in the profile. However, only a subset of these tests may have needed to be performed on your specimen. You should verify accuracy of codes listed; and where multiple codes are listed, you should select codes for the tests actually performed on your specimen.

BLOODWORKS ASSUMES NO RESPONSIBILITY FOR BILLING ERRORS DUE TO RELIANCE ON CPT CODES LISTED IN ITS TEST CATALOG. For further reference, consult the CPT Coding Manual published by the American Medical Association; if you have questions regarding use of a code, contact your local Medicare carrier.

Recommended CPT codes are listed under each test online. Go to our Testing Index. Click on the test you are ordering and scroll down to the section titled CPT code. Be sure to review our recommended CPT codes with your insurance and state carriers as they reflect our interpretation of the AMA CPT code handbook.

STAT testing is available for some of our assays. Some STAT testing has an extra fee associated with it. The specific testing laboratory will be able to advise you if STAT testing is available and what STAT charges will be applied. Please contact the laboratory directly. Please see above under Contact for specific laboratory phone number.

Tests and panels can be canceled without charge if the notification is received before the sample has been processed.

Invoices are issued on a monthly basis and are sent when a test has been completed. The institution referring the sample is responsible for payment. Please submit all information for payment, including a purchase order number if required and billing address, on the requisition that is sent with the sample.

Bloodworks Northwest bills the referring institution unless the patient is an outpatient Medicare enrollee or a Medicaid recipient from Washington. Information that will have to be given at time of service is the following:

• Clarification whether or not this is the primary or secondary insurance of the patient
• Member ID
• Date of Birth/Gender
• Patient Complete Mailing Address
• Patient Telephone number
• Physician Ordering
• Physican NPI Number
• ICD-10 Code for Patient

Possibly, the specific lab where testing is to be done needs to be contacted to make sure all necessary information is given. Please contact the laboratory directly.

We can offer your patients the option to pay directly for laboratory testing. We will accept a check, money order, VISA® or MasterCard® as advance payment. The following information would also need to be provided before testing is performed.

• First and Last name of Patient
• Patient’s Social Security Number
• Date of Birth/Gender
• Patient Complete Mailing Address
• Patient Telephone number
• Copy of Patient’s Insurance information
• Subscriber’s name on Insurance
• Subscriber’s ID or Policy Number and Group Number

Please send the check, money order or credit card information with the sample. Credit card information includes 16-digit account number, name as it appears on the credit card, billing address, expiration date, 3-digit security code, and whether the card is a VISA or MasterCard, as well as the card owner’s phone number.
