Final answer:
The guidelines at the beginning of each section in the CPT manual that provide specific coding rules for that section are known as the CPT Guidelines. ICD codes are used in medical laboratories to identify necessary tests and by health-care management systems to ensure appropriate treatments are provided.
Step-by-step explanation:
The guidelines located at the beginning of each section of the CPT manual, which provide specific coding rules for that section, are known as the CPT Guidelines. In the healthcare field, ICD codes play a significant role in various areas. When a patient seeks treatment for a viral infection, an ICD code may be used by the clinician to order the necessary laboratory tests specific to the suspected virus, which will inform the treatment plan.
These codes are utilized by medical laboratories to determine the tests needed to confirm the diagnosis. Moreover, ICD codes are employed by the health-care management system to ensure that all treatments and tests are relevant and appropriate for the particular virus.
Medical coders use these ICD codes to assign the corresponding codes for the procedures that were carried out. Then, medical billers rely on this coded information to process insurance claims for reimbursement. Furthermore, vital-records keepers record the cause of death on death certificates using ICD codes, and epidemiologists utilize these codes to calculate morbidity and mortality statistics.
To directly answer the student's question, you are likely to find an ICD code being used in medical laboratories and within the health-care management system to communicate diagnoses, treatments, and billing information efficiently.
