Final answer:
To locate ICD-10-CM codes for hypertensive heart disease, refer to the circulatory system section of the codebook. ICD codes are found in medical records for treatment and billing, as well as on death certificates for statistics.
Step-by-step explanation:
When using the ICD-10-CM codebook to locate the diagnosis codes for hypertensive heart disease, you would typically refer to a section that addresses diseases of the circulatory system. Hypertension is categorized as elevated blood pressure persistently at or above 140/90 mm Hg, which can lead to various complications including heart disease. In applying ICD codes, medical coders assign the specific code that correlates with the patient's condition, which are then utilized by healthcare providers and insurance companies for treatment planning, billing, and statistical purposes.
Two common places where you would likely find an ICD code include medical records within healthcare institutions for treatment and billing purposes, and on death certificates to record cause of death for statistical analysis by epidemiologists and vital-records keepers.
