Rule 18 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Rule 18 of the Income-tax Rules, 2026 sets sixteen requirements for approving a hospital under section 17(2)(b)(ii) and lists the thirteen prescribed diseases whose treatment escapes perquisite value.
The approval requirements in rule 18
Sub-rule (1): in granting approval to a hospital other than a hospital for Indian system of medicine and homeopathic treatment, the Principal Chief Commissioner or Chief Commissioner shall satisfy himself that the hospital is registered with the local authority and fulfils the following. The 1962 parallel is rule 3A.
| # | Requirement |
|---|---|
| (a) | The building complies with the municipal bye-laws in force |
| (b) | Rooms are well ventilated, lighted and kept in clean and hygienic conditions |
| (c) | At least ten iron spring beds for patients |
| (d) | At least one properly equipped operation theatre, minimum floor space 180 square feet, with a separate sterilisation room |
| (e) | At least one labour room, minimum 180 square feet, where the hospital provides maternity services |
| (f) | Aseptic conditions maintained in the operation theatre and labour room |
| (g) | A duty room for the nursing staff on duty |
| (h) | Adequate storage space for medicines, food articles, equipment and similar articles |
| (i) | The water used is fit for drinking |
| (j) | Adequate arrangements for isolating septic and infectious patients |
| (k) | Provision and maintenance of: high pressure sterilizer and instrument sterilizer; oxygen cylinders and necessary attachments; adequate surgical equipment, instruments and apparatus including intravenous apparatus; a pathological laboratory for testing blood, urine and stool; an electro-cardiogram monitoring system; and a stand-by generator for power failure |
| (l) | At least one qualified doctor on duty round the clock for every twenty beds or fraction |
| (m) | Where there are intensive care unit facilities, at least two qualified doctors round the clock exclusively for the ICU |
| (n) | One nurse on duty round the clock for every five beds or fraction |
| (o) | Where there are ICU facilities, at least four nurses exclusively for every four beds or fraction in the ICU |
| (p) | A record of health of every patient with name, address, occupation, sex, age, date of admission, date of discharge, diagnosis and treatment undertaken |
Conditions (m) and (o) of rule 18 require doctors and nurses exclusively for the intensive care unit — they are additional to the general (l) and (n) ratios, not a substitute. And the ICU nurse ratio is four nurses for every four beds, against one nurse for every five beds on the general ward: a twentyfold difference in nursing density that a hospital seeking approval has to be able to evidence on a roster, not just in principle.
Indian system of medicine and homeopathy
Sub-rule (2): for such a hospital, the Principal Chief Commissioner or Chief Commissioner satisfies himself that it fulfils the conditions in the Office Memorandum dated 6 June 2002 issued by the Department of Indian Systems of Medicine and Homeopathy, Ministry of Health and Family Welfare, for approval of private hospitals for Central Government Health Scheme beneficiaries and Central Government employees.
So there are two separate approval standards under rule 18 — the sixteen-item list for a conventional hospital, and an external memorandum for an AYUSH or homeopathy hospital.
The thirteen prescribed diseases and ailments in rule 18
- Cancer.
- Tuberculosis.
- Acquired immunity deficiency syndrome.
- Disease or ailment of the heart, blood, lymph glands, bone marrow, respiratory system, central nervous system, urinary system, liver, gall bladder, digestive system, endocrine glands or the skin, requiring surgical operation.
- Ailment or disease of the eye, ear, nose or throat, requiring surgical operation.
- Fracture in any part of the skeletal system or dislocation of vertebrae requiring surgical operation or orthopaedic treatment.
- Gynaecological or obstetric ailment or disease requiring surgical operation, caesarean operation or laparoscopic intervention.
- Ailment or disease of the organs at (d), requiring medical treatment in a hospital for at least three continuous days.
- Gynaecological or obstetric ailment requiring medical treatment for at least three continuous days.
- Burn injuries requiring medical treatment for at least three continuous days.
- Mental disorder — neurotic or psychotic — requiring medical treatment for at least three continuous days.
- Drug addiction requiring medical treatment for at least seven continuous days.
- Anaphylactic shocks including insulin shocks, drug reactions and other allergic manifestations requiring medical treatment for at least three continuous days.
Items (d) to (g) of the rule 18 list turn on a surgical operation; items (h) to (m) turn on a minimum continuous stay — three days for most, and seven days for drug addiction. The same organ system can therefore qualify by either route. What does not qualify is outpatient or day treatment of a condition in the second group, however serious, because the stay requirement is not met.
The three definitions rule 18 supplies
| Term | Meaning |
|---|---|
| Nurse | A person who holds a certificate of a recognised Nursing Council and is registered under any law for the registration of nurses |
| Qualified doctor | A person who holds a degree recognised by the Medical Council of India and is registered by the Medical Council of any State |
| Surgical operation | Includes treatment by modern methodology such as angioplasty, dialysis, lithotripsy, laser or cryo-surgery |
The third definition is the one that most often decides a case. Because dialysis and angioplasty are expressly brought within "surgical operation", a condition in the item (d) group treated by either method qualifies without needing a three-day stay.
Worked example
| Facts | Position under rule 18 |
|---|---|
| Hospital with eight beds seeking approval | Fails condition (c) — at least ten |
| Hospital with a 160 square foot operation theatre | Fails condition (d) |
| 25-bed hospital with one doctor on each shift | Fails (l) — one per twenty beds or fraction means two |
| ICU staffed from the general nursing pool | Fails (o) — nurses must be exclusive to the ICU |
| Coronary angioplasty at an approved hospital | Qualifies — surgical operation by definition |
| Two-day admission for a burn injury | Fails — three continuous days required |
| Ten-day inpatient treatment for drug addiction | Qualifies — seven days required |
| Ayurveda hospital | Approved on the 6 June 2002 Office Memorandum conditions |
Compliance checklist
- Confirm the hospital is registered with the local authority before anything else.
- Evidence all sixteen physical, equipment and staffing conditions.
- Compute the doctor and nurse ratios on beds or fraction, and separately for the ICU.
- Keep rosters showing round-the-clock and ICU-exclusive cover.
- Maintain the patient health record with all nine listed particulars.
- For an AYUSH or homeopathy hospital, work to the 6 June 2002 Office Memorandum.
- Match the treatment to one of the thirteen prescribed diseases, by the surgery route or the stay route.
- Check whether the procedure falls in the extended "surgical operation" definition.
- Verify the treating doctor's MCI-recognised degree and State registration.
Common mistakes
- Counting ICU staff towards the general ward ratios.
- Assuming any serious illness qualifies without surgery or the minimum stay.
- Applying the three-day rule to drug addiction, which needs seven.
- Treating dialysis as non-surgical.
- Using the sixteen-item list for an Indian system of medicine hospital.
