Discussion
Discuss the differences in the coding guidelines guideline that states the physician must make a connection or a causal relationship between hypertension and heart disease in order to appropriately use the ICD-10-CM category I11, hypertensive heart disease versus the coding guideline that states the physician does not have to make a connection or causal relationship between hypertension and chronic renal failure or chronic kidney disease in order to appropriately use the category I12, hypertensive chronic kidney disease.
Why is there a difference? What is the difference? Why does it matter? Support your answers with a specific coding example.
