Final answer:
The codes related to lab tests can be found in the Pathology and Laboratory section. For neurological exams, the coordination exam includes walking subtests. Medical imaging techniques vary, including CT scans, MRI, PET scans, and ultrasound, each with specific uses.
Step-by-step explanation:
The codes related to lab tests performed can be found in the Pathology and Laboratory section of medical coding resources. This section comprises a range of codes that are assigned to various laboratory tests and analyses, which healthcare providers use to diagnose and monitor patient health. Lab tests could include blood work, pathology studies, cultures, and other biochemical assessments.
In the context of a neurological exam, the major section that includes subtests related to walking is the coordination exam. This part of a neurological assessment involves tests that evaluate the coordination and fine motor skills, which are essential for activities such as walking, balance, and other movements. These subtests are particularly focused on the cerebellar function, which is the part of the brain that regulates movement coordination and balance.
When it comes to medical imaging techniques, various methods are used depending on the purpose of the exam: CT scans provide detailed cross-sectional images of the body, MRI uses magnetic fields to produce images of organs and structures, PET scans measure active blood flow and physiological activity using radiopharmaceuticals, and ultrasound technology is widely used in monitoring pregnancies, being the least invasive and not using electromagnetic radiation.
