Using the coding techniques you have learned, carefully read through the case study and determine the most accurate diagnosis code(s). Remember, check the chapter-specific, subchapter-specific, and category-specific notations within the Tabular List. Then, determine the most accurate procedure code(s) along with any modifier(s), if appropriate. MORRIS, SHALLERT & ASSOCIATES Allergy & Immunology 975 CENTRAL AVENUE • SOMEWHERE, FL 32811 • 407-555-4321 PATIENT: GARRISON, JUSTIN ACCOUNT/EHR #: GARRJU001 This 31-year-old male came in with complaints of clogged sinuses. I have not seen this patient since last year, when he was experiencing severe hay fever symptoms. Patient states that he recently started dating a woman who has a pet cat. He noted symptoms the first time he visited her home. HEENT: His sinuses appear to be congested. Throat and nasal passages are mildly inflamed. Upon visual inspection, the ears appear unremarkable. Because complete allergy testing had not been done previously, we performed full-spectrum, percutaneous (scratch) testing. Tests confirmed some mild food allergies and a severe allergy to cat dander. DX: Allergy to animal dander (cat) RX: Allegra PLAN: Patient states he does not want to be dependent on medication for the rest of his life. After discussions of benefits and concerns, he opts to begin weekly desensitization injections.
