Medical Reimbursement added in gross salary i.e. section 17 (1)

An employee is seeking clarification on why their employer added a medical reimbursement of £1.5 lakh to their gross salary for FY 2021-22, despite the employee bearing the hospitalisation costs themselves. The employer also deducted TDS on this amount. The query asks if there's a way to claim a tax benefit for this reimbursement during ITR filing, as it's being taxed as a perquisite under Section 17(2) of the IT Act.
