Start with a clinic in a specialty you or your doctors practise, not a hospital, which is one of India's most capital-heavy and regulated businesses. Registration comes first: in the 19 States and UTs that follow the Clinical Establishments Act 2010 you register on the national portal (provisional first, permanent once minimum standards are met), and other states run their own nursing-home or clinic laws. Then get bio-medical waste authorisation from the state pollution control board and a contract with a treatment facility, AERB clearance before installing any X-ray or CT, a drug licence from the state drug controller for an in-house pharmacy, plus the fire NOC and trade licence. Every doctor must be registered with the medical council. Aim for NABH entry-level certification, which insurers look for. What kills most is the doctors: build around doctors who will stay, and talk to a healthcare-compliance lawyer for your state before signing a lease.
The national portal for registering a clinic, nursing home or hospital under the Clinical Establishments Act 2010, with its minimum standards and provisional and permanent registration. The Act applies in 19 States and UTs; other states have their own laws.
The Central Pollution Control Board's page for the Bio-Medical Waste Management Rules, under which every clinic or hospital generating such waste needs authorisation from the state pollution control board and a contract with a treatment facility.
India's national drug regulator under the Drugs and Cosmetics Act 1940 and Rules 1945. It sets the rules; state licensing authorities issue most manufacturing and sale licences.
India's hospital accreditation body. Its entry-level certification is the usual first step for a new hospital or clinic, and it is what insurers and empanelment schemes look for.
