The classification of power and fuel expenses as either direct or indirect expenses depends on the specific context and accounting practices of the hospital. Generally, if power and fuel expenses can be directly traced and allocated to a particular cost center or department within the hospital, they may be considered direct expenses. On the other hand, if these expenses are incurred for the overall operation of the hospital and cannot be directly attributed to a specific cost center, they may be treated as indirect expenses. It is advisable to consult with a professional accountant or refer to relevant accounting standards for accurate categorization based on the hospital's specific circumstances.
