There are chances for you in many ways. Now it is up to you to think and make a decision as deemed fit.
1. You have a B.Tech in Biotechnology. You have 6 years of experience in medical coding. In this field also you are many chances to go to the next level. For that, you may have to do your MBA in distance mode while you are working. By the time you complete an MBA, you will have 9 years' experience. With that, you have every chance to get jobs in higher scales and top positions. Salary may go more than 12 lakhs per annum also. It all depends on your post and the company you work in.
2. Business Analytics is also a field with many job chances. The pay structures are very good. But the experience you put in so far may not be useful. So getting a job in a good company will be difficult. You have to join in any company and put up some service. Then you will get a good job. But in this line, you have to make hard work. Otherwise, it will be very difficult these days to settle in a new job and prosper.
3. Even in the IT sector also the salary will not go up overnight. Initially, you have to work hard and the payment will be less only. I know IT employees drawing 10 to 12 LPA after putting up 8 years of service. But your experience will not be considered. SO again you have to start with a low salary.
The best course of action will be to continue in the same line, improve your qualification and then shift the job to a big company into a higher position.
