Final answer:
The code book for reporting a diagnosis of chronic kidney disease is the ICD-10-CM, which is used for classifying diseases for various purposes including billing and statistical tracking.
Step-by-step explanation:
The correct code book used to report a patient's diagnosis of "chronic kidney disease" is C. ICD-10-CM. The International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) is utilized in the clinical field to classify diseases and is responsible for providing a standardized system for coding the diagnoses and conditions for billing and epidemiology. HCPCS Level II is primarily for products, supplies, and services not included in the CPT codes, like equipment and medication. Current Procedural Terminology (CPT) codes are used for reporting medical procedures and services. ICD-10-PCS, on the other hand, is for hospital procedure coding in the United States and is not used to code diagnoses.
Medical coders would reference the ICD-10-CM to assign the proper code for chronic kidney disease, and medical billers would use this information to process claims for reimbursement from insurance companies. Similarly, epidemiologists and vital-records keepers would use ICD codes to track mortality and morbidity statistics.
