A co-payment is the amount a patient must pay up front for a service based on the patient’s insurance policy with their insurance carrier.
What is “patient responsibility” on my invoice?
Patient responsibility is the amount a patient must pay for a service according to his or her insurance plan. The patient may need to satisfy his or her deductible, pay for services not covered under his or her insurance plan or pay for amounts that exceed the patient’s annual maximum benefit.
Why do I owe MDL if my insurance has already paid?
Your insurance carrier and policy states the benefits that are paid for laboratory services. Whether you use an in-network or an out-of-network provider, you could still be responsible for a portion of the services depending on the benefits of your policy. After MDL has received payment from your insurance carrier, if there is a deductible, co-pay, co-insurance, or patient responsibility, you will be billed for that portion. This is the amount you owe to MDL.

Do I have to provide diagnosis information codes for ordered laboratory tests?
Diagnosis information is required to be included on each test requisition. The best practice is to choose an ICD-9 diagnosis codes, however the physician or other authorized ordering clinician may include a clear description of the diagnosis information for the patient, as long as it follows the type of description used by the World Health Organization (WHO) when it establishes diagnosis codes.
How do I choose a correct ICD-9 code for MDL’s testing?
Physicians or other persons authorized to order laboratory tests must submit diagnosis codes that reflect signs, symptoms, complaints, and reasons for the encounter of your patient. Such information should also be documented in the patient’s medical records for the date of service in which the testing was ordered. If symptoms are present, but a definitive diagnosis has not yet been determined, choose diagnosis codes that reflect the symptoms the patient presents at his or her office visit. It is the ordering clinician’s responsibility to choose ICD-9 diagnosis codes and MDL does not choose diagnosis codes under any circumstances.
Can a physician order additional tests after the patient specimen has already been sent to MDL?
Testing can be added to a request if the specimen volume permits and it is within an allowable time period from specimen collection. All test additions must be received in writing and faxed to MDL’s QA/QC Department at 609.570.1020.

What is Cystic Fibrosis (CF)?
Cystic Fibrosis, usually diagnosed in the first few years of life, is an inherited, life-long illness that is characterized by problems with the lungs and digestive tract of its sufferers.
What is the purpose of Cystic Fibrosis Carrier Screening?
The purpose of CF carrier testing is to see if a couple is at increased risk for giving birth to a child who will have CF prior to conception through prenatal screening. The American Congress of Obstetricians and Gynecologists (ACOG) recommends carrier screening be offered to the following populations prior to conception or within the first or early second trimester of pregnancy:
- Individuals with a family history of CF
- Reproductive partners of individuals with CF
- Couples in whom one or both partners are Caucasian of Ashkenazi Jewish or European decent and are planning pregnancy or seeking prenatal care
While these groups constitute those at highest risk of CF transmission, individuals at lower-risk should also be provided with counseling and screening information.
Why do you need the patient’s ethnicity for Cystic Fibrosis Testing?
The incidence and carrier risk for CF varies greatly based upon race or ethnicity. This information is required to complete the result interpretation process.

What is the clinical significance of the six 6 reflexed mutations? If the patient is positive for one of the 32 mutations they are a carrier, why do we do the reflexes?
The American Congress of Obstetricians & Gynecologists (ACOG) recommends that testing offered include these six mutations.
Why does MDL require two swabs when collecting genetic tests?
Two swabs are requested for all genetic based assays to ensure adequate amounts of human genomic DNA are obtained for analysis.
What type of testing do you have available for Swine Flu?
MDL currently performs Test 1125 2009 H1N1 Influenza Virus (Swine Flu) with tamiflu resistance by Pyrosequencing.
Is MDL’s testing methodology the same as the Centers for Disease Control and Prevention (CDC) methodology?
Yes. Both the genetic region and methodology parallel the CDC’s approach with slight variation.
What type of specimens do you accept for H1N1 testing?
We accept a swab of nasopharyngeal surfaces collected with a NasoSwab™
What is tamiflu resistance?
Tamiflu (oseltamivir), is an antiviral drug often used to treat influenza. According to the CDC in the 2007-08 flu season, reports indicated that worldwide there was a significant increase in the incidence of oseltamivir, or Tamiflu, resistance among H1N1 viruses and that in the U.S. 10.9% of H1N1 viruses tested were resistant to Tamiflu, which presents a problem for treatment.
Does MDL report positive H1N1’s to the state health departments?
Each state has their own reporting requirements for laboratories. We forward positive H1N1 results to the states that require such reporting.
What type of testing do you have available for MRSA?
There are two assays currently available from MDL for MRSA testing. Test 1118: Methicillin resistant Staphylococcus aureus (MRSA) by conventional PCR and Test 1119 Panton-Valentine Leukocidin (PVL) DNA by Real-Time PCR.
What is the difference between the two tests available for MRSA?
Test 1118 will determine if MRSA or Methicillin Susceptible Staphylococcus aureus (MSSA) is present in a sample. If Test 1118 returns a positive result, then 1119 can differentiate hospital and community associated MRSA.
Test 1118 also has the ability to determine the type of a mobile genetic element or transposon within MRSA called the Staphylococcal Cassette Chromosome (SCC) which carries the genes that cause methicillin resistance such as mecA. There are 4 main types of SCCs named type I, type II, type III, and type IV. SCC type I, II, and III are typically found in Hospital Associated MRSA (HA-MRSA) strains, while Type IV in conjunction with a positive PVL gene, test 1119, are typically found in Community Associated MRSA (CA-MRSA) strains. The SCC types within HA-MRSA strains also typically have other antibiotic resistance genes associated with them that could limit the number of alternative antibiotics used to treat MRSA. The CA-MRSA is typically a more virulent MRSA strain that can cause more aggressive infections, however the SCC type IV does not typically contain other antibiotic resistance genes, therefore when detected early can be easily treated with a number of alternative antibiotics
What type of specimens do you accept for MRSA testing?
We accept a swab of nasopharyngeal surfaces collected with a NasoSwab™ or swabs of skin surfaces, boils, vaginal and anal tracts using the OneSwab®.
