Chromosome 16 contains the genetic codes for the zeta and alpha hemoglobin chains.Each chromosome has two loci alpha chains 1 and 2. This equals a total of four loci of material coding for the alpha hemoglobin chain. See the image for a visual representation of these loci.In the genotypic notation of alpha thalassemia an "" represents the presence of an alpha locus. A "-" represents a deletion of a locus.The notation for the normal number of alpha loci is /. The amount of Hb A produced by this normal gene is 97-98 %.(drawing modified from Harmening, 1999)

The definitive identification of C. septicum can be made using a profile of biochemical reactions, as is contained in the RapID ANA strip (see photograph). The upper set of tubules are reactions before addition of reagents; the bottom set of reactions after reagents are added.The upper set of letter codes is used to read the reactions before addition of reagents; the lower set of labels indicate the tests to read following addition of reagents.Of all the reactions included, only ONPG and NAG in the upper set are positive.The biotype number derived from this profile of reactions, 014000 codes for Clostridium septicum, thus confirming the identification.

A gene is a hereditary unit or sequence of the nucleotide bases ACGT, occupying a fixed location or locus on the chromosome. It is these genes that carry all the information for life processes.DNA is rewritten into 3 types of RNA, each with a specific task: Messenger RNA (mRNA)carries the protein message to the cytoplasm. Ribosomal RNA (rRNA) is the location of protein synthesis. Transfer RNA (tRNA) is responsible for amino acid transport.Each 3-base nucleotide sequence (codon) codes for a specific amino acid. Some amino acids have more than one codon to direct their placement; this is termed degeneracy.

The reason to chose a particular molecular method can be influenced by disease detection, monitoring or therapy in certain patient populations. Molecular methodologies can be used to identify alterations or variations or changes in DNA sequencing that can cause disease. Sequence alterations that are known to cause disease are termed mutations. These changes or mutations can be applied to areas of the clinical lab such as infectious disease, paternity, genetic testing, and pharmacogenetics. Some of the more common alterations are:Deletion: a missing nucleotide or other portion of DNA sequence Insertion: an extra DNA nucleotide or other portion of DNA sequence Missense: a nucleotide or sequence substitution that codes for a different amino acidNonsense: a nucleotide substitution that ends in early termination of the protein manufacturing process; usually due to a stop codon.The most common alteration is a single base change or single nucleotide polymorphism (SNP)

A hemochromatosis gene, HFE, was identified in 1996. Mutations in the HFE gene are found in the majority of patients diagnosed with hereditary hemochromatosis (HH). The locus for the gene is on the long arm of chromosome 6 where it codes for a membrane protein, HFE. The exact mechanism of the role of HFE protein in iron metabolism is incompletely understood. It is thought that HFE, along with a second protein, beta-2 microglobin, interacts with transferrin receptors (TfR) on cell membranes. This interaction supresses the affinity of transferrin for TfR, thus lowering the uptake of transferrin--and its attached iron--into the cell. Transferrin receptors have been found on the surface of a variety of cells, with the greatest concentration on cell membranes of intestinal cells, hepatocytes, and RBC precursors. In addition to HFE, HH is also associated with mutations in other genes involved in iron homeostasis, including hemojuvelin (HJV), TfR, hepcidin, and ferroportin. Hepcidin production is reduced in HH due to all of these genetic causes, with a resulting increase in iron absorption. Mutations in HFE are the most common cause of HH.

CPT (Current Procedural Terminology) codes are used to describe specific tests or services. The amount of payment for a test is dependent on the CPT code. It is against the law to use the wrong CPT code for a test for the purpose of causing or increasing payment for a test. ICD-9CM (International Classification of Disease, 9th Edition, Clinical Modification) codes are used to classify diseases and conditions, and describe signs, symptoms and medical circumstances. ICD-9CM codes are used to indicate the medical necessity of a particular test. It is against the law to use the wrong ICD-9CM code for the purpose of causing or increasing payment for a test.

Requisitions must be designed to ensure that ordering physicians can choose tests that are medically necessary for their patients. Requisitions should contain reminders about Medicare rules of medical necessity and list the contents of panels and profiles. Requisitions must provide a place for the physician to include diagnosis (ICD9-CM) codes. Physicians should be encouraged to use only the requisitions supplied by the laboratory to order tests. Ambiguous or unclear test orders When the orders for a test are not absolutely clear, the laboratory must contact the ordering physician to clarify the orders before performing and billing for the test. The laboratory cannot guess at the order. The laboratory cannot perform and bill for tests that are not specifically ordered. The laboratory cannot change a physician order without contacting the physician. In any case where specimen integrity or patient care will be compromised by a delay in testing follow the policies the laboratory has established for such cases.

The laboratory's couriers may not transport items except those related to the testing services offered by the laboratory. Couriers must follow all OSHA standards for the handling and transport of specimens. The laboratory is responsible for all tests it refers to other laboratories. Laboratory should not change CPT codes supplied by a reference laboratory without contacting the reference laboratory. The laboratory is responsible for all tests it bills to Medicare/Medicaid even if the test was performed by a reference laboratory.

ICD-9CM (International Classification of Disease, 9th Edition, Clinical Modification) codes are used for the classification of disease and conditions and for describing signs, symptoms and medical circumstances.These codes are used to indicate the medical necessity of a particular test.ICD-9 codes can only be supplied by the ordering physician or a representative of that physician. "Code steering" means to steer or direct a physician to supply an ICD-9 code that is payable. ICD-9 codes cannot be used from a previous laboratory order. If a physician supplies a narrative description instead of an ICD-9 code the laboratory must accurately translate that code using only certified coders.It is against the law to use the wrong ICD-9 code for the purpose of causing or increasing payment for a test.

Secure sensitive and confidential documents and materials.Follow all security procedures and never give your password or other codes to any other employee.Be aware of aberrant behavior and excessive questioning about billing or other compliance risk areas.Stay current on compliance policies and procedures, laws and regulations.Don't guess at an employee's questions. If you don't know for sure, find out before answering.Report any suspect activity by an employee to the compliance officer.

The setting is a billing office in a laboratory where two or more clerks work together in very close proximity with each other, so that each can easily see what the other is doing. A billing clerk notices that one of his fellow employees is changing or adding codes to requisitions he is processing. This employee is a friend of his and he knows that he really needs the job at the laboratory because he is a single parent raising two kids. He also knows that what the employee is doing is against the company's compliance policies.He asks the employee about it and is given the explanation that because the computer requires something to be entered in the ICD-9 code field and he only does this with non-Medicare patients, it doesn't matter. The employee explains that it saves him a lot of time he uses to call to get codes for the Medicare patients. What should this clerk do about this?Correct Answer: She should talk to the supervisor about the problem even if she talks to the employee about it and the employee says she will talk to the supervisor and stop doing it.Discussion: Every employee who becomes aware of a violation of the law or a compliance policy has a responsibility to take action, which includes reporting the problem to a supervisor or the compliance officer. It doesn't matter that these patients are not Medicare patients, the important thing is that the employee is violating a compliance policy. If this employee does not report the problem he is himself violating a compliance policy. If it is subsequently discovered that he knew and didn't report it, he could be terminated. If there is a need for refunds to be done or other action, it will not occur and could create a big problem for the lab in a subsequent audit or other action.

ICD-9CM (International Classification of Disease, 9th Edition, Clinical Modification) codes are used for the classification of diseases and conditions, and for describing signs, symptoms and medical circumstances. These codes are used to indicate the medical necessity of a particular test. All employees who are directly or indirectly responsible for reporting to Medicare must be aware of these guidelines to prevent fraudulent claims: ICD-9 codes can only be supplied by the ordering physician or a representative of that physician. ICD-9 codes cannot be used from a previous laboratory order. If a physician supplies a narrative description instead of an ICD-9 code the laboratory must accurately translate that code using only certified coders.
