Which codes correctly report hypertension due to systemic lupus erythematosus?

• A. I15.9, M32.10
• B. M32.9, I10
• C. E11.9, I10
• D. M32.10, I15.8

Answer: (D)

When hypertension is caused by another disease, code the underlying condition first and then use a code for secondary hypertension. Here, systemic lupus erythematosus (SLE) is the underlying condition, and the hypertension is a secondary effect. If there’s no specific organ involvement noted, use the SLE code for a case without organ involvement, which is M32.10. Since the hypertension is secondary to the SLE, code for secondary hypertension as I15.8 (Other secondary hypertension) rather than I10 (essential hypertension). Using I15.9 would be less precise when the underlying cause is known. The other codes (like E11.9 for diabetes or using I10 alone) don’t reflect the secondary nature of the hypertension due to SLE. So the correct pairing is M32.10 for SLE without organ involvement plus I15.8 for the secondary hypertension caused by SLE.
