Chief Minister's Comprehensive Health Insurance Scheme (CMCHIS) in Tamil Nadu: A Complete Guide

Medically reviewed by Dr. Nikhil Singh
Last reviewed: 11 Aug 2026
The Chief Minister's Comprehensive Health Insurance Scheme (CMCHIS) is the flagship health insurance program of the Government of Tamil Nadu, designed to provide quality healthcare to eligible families across the state. Initially launched in 2009 as the 'Chief Minister Kalaignar Insurance Scheme for life saving treatments' (Kalaignar Kaappittu Thittam), it was restructured and launched as CMCHIS in 2012.
In a significant move to enhance healthcare access, Tamil Nadu integrated its state scheme with the central government's Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB-PMJAY) in September 2018. The scheme is now co-branded and collectively known as AB-PMJAY - CMCHIS. This integration expanded the coverage for beneficiaries to ₹5 lakh per family per year on a floater basis.
The scheme operates entirely on a cashless basis at a wide network of empanelled government and private hospitals. It aims to reduce the financial burden on low-income families by covering expenses for a vast range of medical procedures, surgeries, and hospitalisation, including treatment for pre-existing conditions from day one.

What Does the CMCHIS Cover?
The AB-PMJAY - CMCHIS provides substantial financial protection to eligible families with a health insurance coverage of up to ₹5 lakh per family per year. This coverage operates on a floater basis, meaning the entire sum can be used by one or more members of the family for one or multiple hospitalisations until the limit is exhausted for that policy year.
The scheme is designed to cover a wide spectrum of medical needs, focusing on secondary and tertiary care. It includes 1,090 medical and surgical procedures, 52 diagnostic procedures, and 8 follow-up procedures. Some official communications mention that the total number of covered procedures exceeds 1,500. A key feature of the scheme is that it covers pre-existing diseases from the very first day of enrolment, without any waiting period.
- **Major Surgeries:** Coverage extends to complex procedures in cardiology and cardiac surgery, neurology and neurosurgery, and orthopaedic surgeries.
- **Specialised Treatments:** The scheme covers cancer care (including chemotherapy, radiotherapy, and surgical oncology), nephrology treatments like dialysis, and organ transplants for kidney, liver, and bone marrow.
- **Maternity and Child Care:** Services for maternity, C-sections, and care for newborns are included under the scheme.
- **Critical and Emergency Care:** High-end procedures, critical care, and trauma care are also covered, ensuring support during medical emergencies.
- **Diagnostic Procedures:** The costs for essential diagnostic tests such as CT scans, MRI scans, and angiograms are covered when required as part of a treatment package.
Who is Eligible for the CMCHIS?
Eligibility for the Tamil Nadu Chief Minister's Comprehensive Health Insurance Scheme is primarily based on residence and annual family income. The state has set its own criteria to ensure a wider population can benefit from the scheme.
The core eligibility requirements for a family are:
In addition to the above, certain other groups are also eligible to enrol in the scheme without an income limit, provided they meet specific criteria:
- The family must be a resident of Tamil Nadu.
- The total annual family income must be less than ₹1,20,000. This limit was recently increased from the previous cap of ₹72,000 per year.
- The applicant's name must be present in the family's smart ration card.
- Sri Lankan refugees who possess a valid migration certificate.
- Migrants from other Indian states who have been residing in Tamil Nadu for a minimum of six months and hold a valid certificate from a designated authority.
- Orphans and children rescued from registered or unregistered organisations and placed in government-approved homes.
How to Enrol and Get the CMCHIS Card
The enrolment process for CMCHIS is conducted offline at designated centres across the state. While the official portal, www.cmchistn.com, can be used to check eligibility status and download an existing e-card, new registrations must be done in person.
To enrol, the head of the family should visit the nearest enrolment kiosk, which is typically located at the District Collector's office, Taluk offices, or designated e-Sevai centres. During the enrolment process, biometric information such as fingerprints and a photograph of the family members will be captured.
The following documents are required at the time of enrolment:
Once the details are verified and biometrics are captured, a CMCHIS e-card is generated. This card contains a unique member ID and is essential for availing cashless services at empanelled hospitals. Beneficiaries can later download and print this e-card from the official scheme website.
- Smart Ration Card of the family.
- Aadhaar cards of all family members to be included in the scheme.
- A valid Income Certificate issued by the Village Administrative Officer (VAO) or another authorised revenue authority.
- A self-declaration form signed by the head of the family.
How CMCHIS Works with Ayushman Bharat PM-JAY
Since September 2018, the CMCHIS has been integrated with the central government's Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (PM-JAY). This integration created a co-branded scheme, now known as AB-PMJAY - CMCHIS, combining the strengths of both programs for the people of Tamil Nadu.
The primary difference between the standalone national PM-JAY and Tamil Nadu's integrated model lies in the eligibility criteria. Nationally, PM-JAY beneficiaries are identified based on the Socio-Economic Caste Census (SECC) 2011 data. However, Tamil Nadu has adopted a 'hybrid model' by extending the benefits to a much larger population. The state uses its own broader eligibility criterion of an annual family income below ₹1,20,000.
This means that all existing and new beneficiaries of CMCHIS who meet the state's income criteria are automatically eligible for the enhanced coverage of ₹5 lakh per year provided under PM-JAY. The smart card issued to beneficiaries in Tamil Nadu features the logos of both the state and central schemes, reflecting this integration.
Using the CMCHIS Card at an Empanelled Hospital
The AB-PMJAY - CMCHIS operates on a 100% cashless basis, which means beneficiaries are not required to pay any money for covered treatments at an empanelled hospital. The scheme does not have a provision for reimbursement of expenses incurred by the patient.
The scheme has a large network of approved healthcare providers. As of early 2023, this included over 800 government hospitals and more than 900 private hospitals across Tamil Nadu. Beneficiaries can find an updated list of empanelled hospitals on the official CMCHIS website.
The process for availing cashless treatment is straightforward:
After the treatment is complete, the hospital submits the final bills and documents to the insurance company for settlement. The patient can be discharged without making any payment for the covered procedures.
- **Step 1:** The beneficiary must present their CMCHIS e-card and Aadhaar card at the dedicated scheme counter of an empanelled hospital.
- **Step 2:** The hospital's coordinator verifies the patient's identity and eligibility using their card details or biometric data.
- **Step 3:** For a planned surgery or hospitalisation, the hospital sends a pre-authorization request to the insurance company with details of the diagnosis and proposed treatment.
- **Step 4:** In case of a medical emergency, treatment can be started immediately. The hospital must then seek pre-authorization within 24 hours of the patient's admission.
- **Step 5:** Once the pre-authorization is approved, the hospital provides the necessary treatment to the patient completely free of cost.
Recent Updates and Developments
The Government of Tamil Nadu continues to strengthen and expand the Chief Minister's Comprehensive Health Insurance Scheme. The scheme's implementation was officially extended for a five-year period from January 11, 2022, to 2027, with United India Insurance Company serving as the administrator.
One of the key recent changes was the increase in the annual family income limit for eligibility, which was raised from ₹72,000 to ₹1,20,000, allowing more families to qualify for the scheme's benefits.
Additionally, the state has enhanced the 'Nammai Kakkum 48' scheme, which provides cashless treatment to road accident victims within the first 48 hours. The treatment ceiling under this initiative, which can be linked to CMCHIS, was increased from ₹1 lakh to ₹2 lakh. Looking ahead, the state's Health Minister announced in August 2026 that the government is actively discussing a further expansion of the CMCHIS to include a broader range of medical procedures, with a decision expected in the near future.
