UPSC Combined Medical Services: The Posts, the Pay and the Bond

The Combined Medical Services Examination (CMS) is UPSC's annual recruitment exam for MBBS graduates into Group A gazetted Medical Officer posts across the Central Health Service, Indian Railways, and municipal corporations. It's structurally the medical counterpart to CSE and ESE — same conducting body, same Group A seniority, its own discipline-specific exam pattern. UPSC CMS 2026 offers 1,358 vacancies, split roughly between 864 posts in the Central Health Service and 450 posts in Railways, with the remainder in municipal corporations.

See the Medical & Healthcare Government Jobs overview for how CMS compares to ESIC, Staff Nurse routes, State Medical Officer recruitment and Defence Medical Services.

Eligibility

• Educational qualification: a final-year-passed or completed MBBS degree from a recognised institute, registered (or eligible for registration) with the National Medical Commission (NMC) or a State Medical Council.
• Age limit: not more than 32 years as of the notified reference date (commonly 1 August of the exam year) — relaxed up to 35 years for Junior Scale posts in the Central Health Service. Standard reserved-category relaxations apply on top of this (SC/ST: 5 years, OBC: 3 years, PwBD: up to 10 years).
• Internship: candidates who've completed MBBS but not yet finished their compulsory rotating internship can typically apply, provided the internship is completed by the time of appointment — check the specific year's notification for the exact cutoff.

Exam Pattern

CMS runs a two-stage structure — written examination followed by a Personality Test — genuinely different from CSE/ESE's three-stage Prelims-Mains-Interview pattern, since CMS has no separate Prelims screening stage:

Total: 600 marks. Unlike CSE/ESE, both written papers count directly toward final merit alongside the Personality Test — there's no qualifying-only screening stage the way CSE/ESE's Prelims works.

Posts You Can Be Allocated To

• Central Health Service (CHS): General Duty Medical Officer — the largest single category by vacancy count.
• Indian Railways: Assistant Divisional Medical Officer (ADMO).
• Municipal Corporations (NDMC, Delhi corporations and similar): General Duty Medical Officer.
• Indian Ordnance Factories Health Services: Assistant Medical Officer.

Allocation depends on your rank in the merit list, available vacancies, and your own preference ordering — broadly similar in spirit to how CSE allocates ranked candidates across services.

Salary

CMS-recruited Medical Officers enter at Pay Level 10, basic pay ₹56,100 — the same entry Pay Level as IAS/IPS/IFoS and ESE officers, since all Group A central services share the same 7th CPC pay matrix. What's genuinely different for medical posts specifically is the Non-Practicing Allowance (NPA) — commonly 20% of basic pay — paid in lieu of the restriction on private practice, a component with no equivalent in non-medical Group A services. Including DA, HRA and NPA, gross monthly pay is commonly cited around ₹1,05,000–1,30,000, with in-hand pay (after standard deductions) commonly cited around ₹75,000–90,000. See our Medical & Healthcare Salary Comparison guide for how this compares to ESIC, state and defence medical pay.

Career Growth

CMS officers progress through the same broad Group A time-scale structure used across central services — rising through Pay Levels over a multi-decade career, with promotion to senior administrative-medical posts (Chief Medical Officer and similar) at more senior stages. Exact promotion timelines vary by which service (Central Health Service, Railways, or municipal corporation) an officer is allocated to, since each maintains its own cadre structure.

Frequently Asked Questions

Is UPSC CMS only for freshly graduated MBBS doctors?

No — it's open to any MBBS graduate within the age limit (32 years, relaxed to 35 for CHS Junior Scale posts), regardless of how long ago they graduated, provided they meet the registration requirement.

Does CMS have a separate Prelims stage like CSE or ESE?

No — CMS runs a single written examination (two papers, 500 marks) followed directly by a Personality Test (100 marks), with both written papers counting toward final merit. There's no qualifying-only screening stage.

What is NPA and how much is it?

Non-Practicing Allowance — commonly 20% of basic pay — paid to government doctors in lieu of being barred from private practice. It applies to CMS-recruited officers and most other civilian government medical posts.

Which posts can I get through CMS?

Primarily General Duty Medical Officer in the Central Health Service or municipal corporations, and Assistant Divisional Medical Officer in Indian Railways, with a smaller number of posts in Ordnance Factories Health Services — allocation depends on your merit rank and preference.

How does CMS compare to State Medical Officer recruitment?

CMS is a single central exam leading to central government posts (CHS, Railways, municipal corporations), while State Medical Officer recruitment is run independently by each state for state government hospitals — see our State Medical Officer Recruitment guide for that route.

In Summary

UPSC CMS is the Group A gazetted route for MBBS graduates into the Central Health Service, Railways and municipal corporations — a two-stage written-exam-plus-interview structure (unlike CSE/ESE's three-stage pattern), entry pay of ₹56,100 at Pay Level 10 plus a 20% Non-Practicing Allowance unique to medical posts, and career progression through the standard Group A time-scale ladder. It's the highest-seniority civilian route covered in this cluster.
