Final answer:
The diagnosis coding for the patient's condition is A. L97.219, I10, F17.210, reflecting the chronic nonhealing venous ulcer, hypertension, and tobacco dependence respectively.
Step-by-step explanation:
The correct diagnosis coding and sequencing for the case mentioned is A. L97.219, I10, F17.210. This is based on the information provided about the patient's chronic nonhealing venous right calf ulceration, tobacco dependence, and hypertension. According to ICD-10 coding:
- L97.219 is used for non-pressure chronic ulcer of the right calf with unspecified severity.
- I10 stands for hypertension without a specified type.
- F17.210 represents nicotine dependence, unspecified, with a history of tobacco use.
It's important to note that the sequencing is influenced by the guidelines which dictate that the code for the primary reason for the encounter should be listed first, which in this case appears to be the chronic ulcer.
