A 61-year-old male is admitted to the hospital for the treatment of a chronic ulcer on his left foot. The patient is currently on furosemide (Lasix) 40 mg every 8 hours to treat edema. The patient undergoes a debridement and partial resection procedure to remove a significant amount of necrotic tissue. Postoperatively, the patient is given IV gentamicin. The patient develops imbalance and visual symptoms. A peak therapeutic drug level is 13 ìg/mL, indicating gentamicin toxicity. The gentamicin is discontinued. The patient is diagnosed with bilateral vestibulopathy due to severe gentamicin toxicity. A synergistic reaction had occurred because furosemide increases the effects of gentamicin.
How is the gentamicin toxicity coded?
A. H81.8X3, T36.5X1A, T50.1X5A
B. T36.5X1A, H81.8X3
C. T36.5X5A, H81.23
D. H81.23, T36.5X5A, T50.1X5A
