Using the coding techniques you have learned, carefully read through the case study and determine the most accurate diagnostic code(s). Remember, check the chapter-specific, subchapter-specific, and category-specific notations within the Tabular List. Remember to use required punctuation and placeholders as necessary to create a complete code meeting specificity guidelines. Then determine the most accurate CPT and/or HCPCS procedure code(s) along with any modifier(s), if appropriate. Please list the Procedure and/or HCPCS code in the appropriate column and add any appropriate modifier(s) in the column directly adjacent to the procedure column titled for modifiers. Case Study: Richard was referred to the hematologist because of persistent easy bruising with purpura and petechiae. Diagnosis at this time is idiopathic thrombocytopenia. In addition to the high-level-complexity consult, testing includes CBC w/platelet count and automated WBC differential, platelet assay (reticulated), and bone marrow biopsy (trocar), which also reveals aplastic anemia.

(a) How does the LDH assay work? Explain why this assay is a good choice to determine platelet adhesion in this experiment. (b) Why are you particularly interested in the proteins Fg and vWF? Explain in terms of the role of these proteins in blood coagulation. (c) Your company would like to use this material for a vascular graft application for small diameter blood vessels. You are asked to modify the material so that it releases an agent that deactivates (nullifies the effects of) either adsorbed Fg or adsorbed vWF. Based on the data presented, for this application, which protein is more important to deactivate and why? (d) Your company has decided to turn its attention towards treating aneurysms (localized, mechanically compromised bulges in blood vessels). One treatment is to encourage clotting within the aneurysm so that blood flow is diverted to nearby vessels instead of stressing the aneurysm. A colleague suggests that a good way to use your material for this application would be to modify its surface to enhance Fg adsorption. Using the data you have already collected, do you agree? Why or why not?

Imagine that you are a human red blood cell returning to the heart after a trip to the head. You decide to amuse yourself by drawing a basic map of your surroundings as the flow of blood carries you along. You label your starting position 1. The following sketch is your completed map, finished upon your return to position 1. (Notice that this time around, you happen to flow through the left leg rather than the head.) Although your map lacks scale and precision, it does successfully describe the path of blood flow around the body. You identify eight distinct locations on your map, labeled 1 to 8.

Share results and analysis with Lab staff and ER staff. 1. What is being used by the Microbiology Department as a blood culture quality indicator? 2. What is the acceptable threshold? 3. What was the actual percentage contamination for the first quarter? 4. Which month has the highest contamination from ER draws? 5. What was the rate of contamination by the laboratory in the same month? 6. What is the action plan for blood culture QA?
