General Information

Medicare Coverage of Laboratory Tests

When ordering outpatient laboratory tests billed to Medicare/Medicaid or other federally funded programs, the following requirements may apply:

  • Only tests that are medically necessary for the diagnosis or treatment of the patient can be billed to Medicare.  Medicare does not pay for screening tests, except for certain specifically approved procedures, and may not pay for non-FDA-approved tests or those tests considered experimental.

  • If there is reason to believe that Medicare will not pay for a test, the patient should be informed.  The patient should sign an Advance Beneficiary Notice (ABN) to indicate that he or she is responsible for the cost of the test if Medicare denies payment.

  • The ordering physician should provide an ICD-10 diagnosis code, not a narrative description.

  • Organ- or disease-oriented panels can be billed only when all components of the panel are medically necessary.

  • Both Deaconess Hospital and any other reference laboratory customized panels should be billed to Medicare only when every component of the customized panel is medically necessary.


Deaconess Hospital Laboratory offers groups of tests based on accepted clinical practice, as well as those that are defined by the American Medical Association Current Procedural Terminology (CPT). All components of these "panels" may be also be ordered individually, unless otherwise indicated.

Referral Testing
Deaconess Hospital Laboratory provides a house test menu of over 1,500 tests and test combinations by selecting primary vendors to perform tests not performed at our laboratory. Primary vendors are selected based upon aspects of service, quality, reliability, turnaround time and price. We reserve the right to change vendors, test parameters and charges for referral testing at any time. For questions please contact Deaconess Hospital Laboratory at 812-450-4LAB

Billing - CPT Coding

It is your responsibility to determine the correct CPT codes to use for your billing. Our Lab Test Directory may serve as a guide. The CPT codes listed reflect our interpretation of CPT codes and requirements. In the case of a test involving several component test, the guide provides a comprehensive list of CPT codes for all possible components of the tests. Deaconess Regional Laboratory is not responsible for billing errors due to reliance on the CPT codes provided in the Lab Test Directory. For detailed assistance, please consult the CPT Coding Manual published by the AMA. If you have questions regarding the use of a code, please contact your Medicare carrier.

Alphabetical Test List Description
Information about specific tests can be found in the alphabetical test listing of the User's Guide. The alphabetical test list contains test numbers, mnemonics; methodologies performed/reported, specimen required, reference interval, interpretive data, CPT codes and notes.

Animal Specimens
Deaconess Hospital Laboratory does not accept animal specimens for laboratory testing.

Computer Downtime

  • Hospital Information System (HIS) - Nursing units will be responsible for placing orders on the “Manual Entry Form” and sending them to Lab. Refer to P&P 10-14 “Epic Downtime Emergency Operational Procedure” for specific detailed information. The manual form either will be picked up by the phlebotomist at the time of collection or should accompany the tubes of blood for those nursing units that collect the specimens. During downtime, Laboratory results will be reported on paper requisitions and sent via the tube system to the appropriate unit. Please check your tube station for reports. The Laboratory will have access to previous test results but will be limited on current results during the downtime. The Laboratory is responsible for entering all lab orders received during the downtime.

Please note that during periods of extended computer downtime some delay with result reporting may occur.

  • Lab Information System (LIS) - If the LIS is inoperable for a length of time, an announcement will be made over email communication. The Laboratory will use paper requisitions for the tests ordered by the HIS. The results will be reported on these paper requisitions and sent, via the tube system, to the appropriate unit. Please check your tube station for reports. The Laboratory will have limited access to previous or current test results during a downtime. Please note that if the HIS is operational, previously performed lab tests will be viewable
  • Anatomic Pathology - Template reports are available if the downtime is extended. Pap smears may be held up to a day before downtime protocol is implemented. Refer to the Anatomic Pathology Downtime Policy, located in the Histology and Cytology Procedure Manuals.

Test Turnaround Time
Expected analytical turnaround times may be found in the test listing section of this User's Guide. Certain tests may take additional time.

Cancellation of Tests
Cancellations received prior to test analysis will be honored at no charge. Cancellation request received after analysis may not be honored. A report is issued automatically and charged appropriately.

Confidentiality of Results
Deaconess Hospital Laboratory and Deaconess Regional Laboratory are committed to maintaining the confidentiality of patient information. To ensure HIPPA compliance, the following policies have been adopted:

Telephone inquiries: Prior to releasing results to a patient, an authorization for medical release must be signed by the patient. Unless noted on the medical release, results will only be released to the patient. Signing up for MyChart will also give patients access to results.

Fax: All faxed laboratory reports are sent with a cover page explaining our confidentiality policies, noting that the material being sent is confidential. Contact information and instructions are provided to the recipient in case of transmittal error.

HIV Screening

The State of Indiana law for HIV screening (IC 16-41-6-1) states that a person may not perform a screening or confirmatory test for the antibody to HIV without the written consent of the individual to be tested or a representative. For physician practices that collect their own blood samples, Deaconess Regional Laboratory requires that the consent be obtained at the time of sample collections and that the consent be kept on location as part of the patient's medical record. By sending DRL a sample and order for an HIV screening the physician's office is acknowledging to DRL that a consent has been obtained and is being kept as part of the patient medical record. As a result, it is not necessary to send a copy of the consent to DRL along with the sample. If the need arises, DRL may request a copy of the signed consent.

Informed Consent Certification
Submission of an order for any tests contained in this User Guide constitutes the certification by the ordering physician that:

  • The physician has obtained the "Informed Consent" as required by any applicable state or federal laws with respect to each test ordered.

  • Patient authorization has been obtained permitting Deaconess Regional Laboratory to report the results of each test ordered directly to the physician.

Critical Values

Critical Values are defined by the Department of Pathology.

Patient Identification Accuracy
The proper identification of patient specimens is strictly adhered to for quality patient care and safety. The College of American Pathologist Laboratory Checklist Commentary GEN 40700 specifies the need for proper identification; "Specimens lacking proper identification or accompanying requisition will not be accepted."

Compliance requires that the same demographic information be properly labeled on the requisition. If a discrepancy has been identified upon receipt of the specimen, we will notify you and reconcile the discrepancy. Specimens lacking two unique patient identifiers or no identification will be rejected.

Reference Ranges
Deaconess Hospital Laboratory strives to provide clear, unambiguous reference intervals.  For example, an age group listed, as 0 to 2 years should be used for all subjects from birth up to their third birthday.  When reference values have been obtained from the literature, Deaconess Hospital Laboratory conducts validation testing to confirm the range.  Deaconess Hospital Laboratory may revise the literature-provided age groups in order to conform to our standard style.

Specimen Rejection
All specimens are unique in their testing requirements. To avoid specimen rejection or delayed turnaround time, check the specimen required field within each test. You will be notified of rejection or problems on receipt.

Please review the following requirements prior to submitting a specimen to Deaconess Regional Laboratory:

  • Full 24 hour for time urine collection

  • Lack of hemolysis

  • Specimen type (plasma, serum, whole blood, etc.)

  • Specimen volume

  • Patient information requested

  • Patient/specimen properly identified

  • Specimen container (metal-free, separation gel, appropriate preservative, etc.)

  • Transport medium

  • Temperature (ambient, frozen, refrigerated)

Specimen Transport

Deaconess Hospital inpatient specimens should be transported to the laboratory soon after collection or within one hour to facilitate testing. Many specimens may shipped in the pneumatic tube system. Please refer to instructions at pneumatic tube systems for acceptable specimens and packing/shipping instructions.

Deaconess Regional Laboratory specimens are stored at ambient, refrigerated, or frozen temperatures at the client's office until transported by a DRL courier.
