Final answer:
When coding for congestive heart failure due to hypertension, you would assign separate codes for each condition: I50 for heart failure and the appropriate code for hypertension.
Step-by-step explanation:
When coding for Congestive Heart Failure (CHF) due to Hypertension, it is important to assign separate codes for each condition. For CHF, you would use the code I50, which falls under the ICD-10-CM category for heart failure. For hypertension, you would use the appropriate code from the ICD-10-CM category for hypertension (such as I10 for essential primary hypertension). Therefore, the codes for the diagnosis 'Congestive heart failure due to hypertension' would be I50 and the specific code for hypertension.
