Yes, I don't think there would be any contravention of law if you take benefit of deduction u/s 80DDB in both the years as the expenditure incurred indeed belongs to both the years in the ratio of 3 days in 17-18 (Rs 90000) and 5 days (Rs 150000) in 18-19.
Infact this would be really effective tax planning for your side provided you have obtained the requisite certificate from the specialist doctor and have deducted any reimbursement from insurance cos. and your employer for the treatment expenditure.
