Combined Medical Services (CMS) Doctor
Work as a doctor in Railways, Central Health Service, ESIC and municipal bodies through UPSC selection.
Facts checked 29/10/2026
Is this for me?
- Treating many kinds of patients, not only one speciality
- A secure government job with a fixed pay structure and promotions
- Public health work, like sanitation and preventing disease in a community
- Very long study: 5.5 years of MBBS, then an exam that draws far more candidates than seats
- Transfers and postings anywhere in India
- No private practice allowed, and the work can be repetitive with heavy patient loads
- Class 11–12 subjects
- Class 12 with Physics, Chemistry, Biology (or Biotechnology) and English, so that you can sit NEET-UG and get into MBBS. The usual NEET rule is at least 50% in PCB for General, 40% for SC/ST/OBC and 45% for PwBD, and you must be 17 by 31 December of the year you join (reported; check the latest NTA bulletin). The CMS exam itself needs a finished MBBS.
- First degree
- MBBS: about 4.5 years of study plus a 1-year compulsory rotating internship, at an NMC-recognised college (reported).
- Entrance exams
- NEET-UG (conducted by NTA) for MBBS admission. Then the UPSC Combined Medical Services Examination (CMSE): a written test and an interview.
- Licence or registration
- You must be a registered doctor (National Medical Commission or State Medical Council registration) to practise. CMS recruits only MBBS doctors (reported).
What the work is like
Treating patients in OPDs, dispensaries and hospitals run by the Central Government, Indian Railways, NDMC and MCD. Also public health work such as sanitation, family planning and health checks, and handling emergencies like railway accidents.
A day in the work
You reach your hospital or dispensary in the morning and see a long OPD queue of patients, many of them government employees and their families. A railway doctor may also check a station health unit, inspect food vendors or look at sanitation in railway colonies. You write prescriptions, order tests, fill registers and sometimes join an emergency call. In the afternoon there are reports and returns to complete, and your team of nurses and staff needs guidance.
The full route: exams, training, registration
- Step 1 · Class 11–12Take Physics, Chemistry, Biology and English. Class 12 marks in PCB and a good NEET score both matter, so build your Biology basics early.
- Step 2 · After Class 12Write NEET-UG and join MBBS through counselling. There is no upper age limit for NEET and no cap on attempts, and the score is valid for that year's admission only (reported). (reported — check with the official body)
- Step 3 · About 5.5 yearsComplete MBBS, including the 1-year internship, and register with the State Medical Council or NMC. UPSC accepts final-year students for the exam. But you must have passed the written and practical parts of the final MBBS exam to be appointed (reported). (reported — check with the official body)
- Step 4 · CMS written exam (yearly)In 2026 UPSC issued the notice on 11 March, took applications till 31 March and held the exam on 2 August. There are two papers of 250 marks each, 2 hours each. Paper I is General Medicine and Paediatrics. Paper II is Surgery, Gynaecology & Obstetrics, and Preventive & Social Medicine.
- Step 5 · Interview (Personality Test)Candidates who qualify the written exam are called for an interview of 100 marks (reported). In 2026 the written result came on 1 September. UPSC then asked qualified candidates to upload documents, and the interview schedule was published on 25 September. Your result is provisional until your documents are checked. (reported — check with the official body)
- Step 6 · Medical fitness and allotmentYou must meet the physical and medical standards given in the exam rules. Your service (Central Health Service, Railways, NDMC or MCD) is then allotted from your final merit rank and your preferences (reported). (reported — check with the official body)
- Step 7 · Training and probationRailway ADMOs join on 1 year of probation and begin with a Foundation Course. Central Health Service and NDMC doctors have 2 years of probation, and it can be extended. You are confirmed after satisfactory service (reported from a copy of the 2026 notice). (reported — check with the official body)
- For CMS 2026, UPSC set the upper age limit at 32 years on 1 August 2026, and 35 years for Central Health Service posts. Vacancies, dates and age limits change every year, so read the latest UPSC notice.
Your real chances
In 2026, UPSC notified 1,358 vacancies: 864 in the Central Health Service, 450 Railway ADMO posts, 14 at NDMC and 30 at MCD. After the written exam, 2,923 candidates qualified for the interview (reported). I could not find the total number of applicants.

What people earn
Pay Level 10 of the 7th CPC Pay Matrix, ₹56,100–₹1,77,500, plus Non-Practising Allowance (NPA) and other allowances. This applies to Central Health Service, Railways ADMO and NDMC posts, and the MCD GDMO Grade-II post starts at the same level (2026 notice) (reported, read from a copy of the UPSC notice).
Pay starts at a fixed government level and rises with yearly increments and promotions, and posting city changes allowances like house rent. You earn less than a busy private specialist, but pay is steady and comes with job security.
Myth and fact
For girls and students with disabilities
The 2026 notice says women candidates are encouraged to apply, and women pay no exam fee. It also reserved 34 Central Health Service vacancies and 18 Railway ADMO vacancies for persons with benchmark disabilities, in listed categories only (for example, the Railway ADMO posts were for locomotor disability). Candidates must still meet the medical standards in the rules, and age relaxation for PwBD is usually 10 years (reported).
