Oxygen therapy reimbursement in India: CGHS, ESIC, Ayushman Bharat, state schemes

Home oxygen therapy in India sits in a reimbursement grey zone. A patient prescribed long-term oxygen therapy (LTOT) may pay anywhere between ₹0 and ₹50,000 per year out of pocket, depending entirely on which government scheme they are eligible for, which private policy they hold, and how the prescription is worded. The rules are scheme-specific, often poorly documented publicly, and meaningfully different across Centre, state, and private-insurance layers. This article unpacks the four biggest pools — Central Government Health Scheme (CGHS), Employees’ State Insurance Corporation (ESIC), Ayushman Bharat PMJAY, and state-level schemes — and closes with what private insurance policies actually exclude.

The patient-level consequence of getting this wrong is substantial. A Central Government retiree who does not file the CGHS paperwork correctly pays ₹35,000 for a concentrator that CGHS would have paid the hospital or vendor for directly. A construction worker enrolled in ESIC who believes ESIC does not cover oxygen equipment is left buying cylinders out of pocket. A family whose patient is covered under PMJAY discovers that PMJAY covers in-hospital oxygen but not a home concentrator rental, and arranges the outpatient therapy through a state scheme the PMJAY authority never mentioned. This article is oriented around making those distinctions explicit so that the patient or family member filing the paperwork understands what is and is not within reach.

CGHS: Central Government Health Scheme

CGHS is the Central Government’s health scheme for serving and retired employees, Members of Parliament, pensioners, freedom fighters, and their dependents. Approximately 4.5 million beneficiaries are covered. CGHS operates wellness centres in around 80 Indian cities and empanels hospitals, diagnostic centres, and medical-device suppliers for cashless and reimbursement-based treatment.

What CGHS covers for oxygen therapy

The short summary: CGHS covers medically necessary in-hospital oxygen therapy in full (as part of the inpatient admission package) and covers home oxygen concentrators and cylinders through a combination of prescription-based issue from CGHS wellness centres and reimbursement against bills from empanelled vendors.

The longer version:

• Inpatient oxygen in an empanelled hospital is covered as part of the daily bed and treatment package. The beneficiary pays nothing at the counter if the hospital processes the admission as cashless; reimbursement routes apply if the admission is non-cashless.
• Home oxygen concentrators are issued on the basis of a CGHS-specialist prescription (typically a pulmonology or internal-medicine consultation at a CGHS wellness centre or empanelled hospital) and a Medical Superintendent’s approval. Issue is either direct from the CGHS store (where stock is available) or through purchase from an empanelled vendor with reimbursement against bills.
• Oxygen cylinders and refills are similarly reimbursable against prescription and vendor bills. Refill frequency and monthly ceiling depend on the prescribed flow rate and duration; chronic high-flow therapy exceeding the notified ceiling requires additional approval.
• Concentrator rental versus concentrator purchase is covered by the scheme but with different approval paths. For short-term needs (post-operative, recovery from an acute episode, palliative care for a limited period), rental is the typical approval. For LTOT indication — GOLD stage III/IV COPD with resting hypoxaemia, severe ILD, pulmonary hypertension with chronic hypoxaemia — purchase is the typical approval, on the rationale that the equipment is needed for years.

Empanelled vendor lists

CGHS publishes a list of empanelled vendors by city. The list is updated periodically (typically annually) and is available from each CGHS additional-directorate office as well as on the CGHS portal. For oxygen concentrators specifically, the empanelled list typically includes three to six vendors per major city. Purchases from non-empanelled vendors are not reimbursed even with a valid prescription; buying from the wrong dealer is a common and avoidable cause of claim denial.

The paperwork

The reimbursement path for a home oxygen concentrator under CGHS typically involves:

1. Specialist consultation at a CGHS wellness centre or empanelled hospital. The consultation note must specify the indication (e.g. GOLD stage IV COPD with SpO₂ < 88% on room air on two occasions), the prescribed flow rate, and the expected duration of therapy.
2. Approval from the Medical Superintendent (for intramural issue) or from the Additional Director of CGHS (for reimbursement of purchase from an empanelled vendor).
3. Quotation from an empanelled vendor for the specific concentrator model being considered. CGHS typically applies a ceiling price derived from its rate contract; spending above the ceiling is reimbursable up to the ceiling only, unless specifically approved.
4. Purchase, installation, and submission of the original invoice, the specialist prescription, the Medical Superintendent’s or Additional Director’s approval, and the beneficiary’s CGHS card details for reimbursement.

Processing time varies; claim resolution within 30–60 days is typical for a clean submission. (CGHS)

What is not covered

• Concentrator accessories beyond standard issue (e.g. premium humidifier chambers, heated tubing for CPAP when the patient is on oxygen rather than CPAP, certain nasal cannula variants) are typically not reimbursed.
• Non-empanelled-vendor purchases are not reimbursed.
• Portable pulse-flow concentrators for travel convenience are reimbursed only in narrow circumstances; the typical grade of approval is for a stationary 5 LPM or 10 LPM unit.

ESIC: Employees’ State Insurance Corporation

ESIC covers employees earning wages below the notified wage ceiling — currently ₹21,000 per month (₹25,000 per month for employees with disability) — along with their dependents. Coverage is funded by employer and employee contributions and runs through ESIC-owned hospitals and dispensaries as well as empanelled private hospitals. Approximately 140 million beneficiaries are covered, making ESIC by a wide margin the largest medical scheme in India by beneficiary count.

What ESIC covers for oxygen therapy

ESIC’s coverage in principle is comprehensive medical care including necessary equipment. In practice for home oxygen therapy:

• Inpatient oxygen during hospitalisation at an ESIC hospital or empanelled private hospital is fully covered.
• Home oxygen concentrators are available on prescription from an ESIC specialist, subject to the local ESIC hospital’s or dispensary’s stock and procurement cycle. Where stock is unavailable, ESIC reimburses the beneficiary for purchase from an approved vendor, at a ceiling rate set by ESIC procurement.
• Cylinder refills are provided through ESIC dispensary channels for beneficiaries on chronic oxygen therapy, with a ceiling on refill frequency matched to prescribed flow and duration.

The practical experience at the dispensary and regional-hospital level varies. In metropolitan cities with larger ESIC hospitals, the process is smoother and delays are shorter. In smaller towns where ESIC presence is via dispensary rather than full hospital, procurement delays of weeks are not unusual, and beneficiaries sometimes front-pay for rental or purchase and seek reimbursement. The reimbursement is available but the delay can be significant.

Key documentation

• ESIC Pehchan card (physical or digital) of the insured person.
• Specialist prescription from an ESIC-empanelled hospital or dispensary specialist.
• Purchase invoice from an ESIC-approved vendor (if reimbursement route rather than direct supply).
• Medical certificate or ESIC-1 form as applicable for extended-therapy cases. (ESIC)

The labour-hour-loss dimension

A distinctive ESIC consideration: if a worker’s oxygen therapy is linked to an employment-related respiratory illness (occupational lung disease in certain high-risk trades — stonecutting, textile dust, construction demolition, chemical exposure), the ESIC claim path can include Permanent Partial Disablement or Permanent Total Disablement benefits in addition to medical equipment coverage. These are separate determinations made under the ESI Act’s benefit schedule; they do not overlap with the medical-equipment reimbursement but can be filed in parallel.

Ayushman Bharat PMJAY

Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB-PMJAY) is the Centre’s flagship scheme providing coverage of up to ₹5 lakh per family per year for secondary and tertiary hospitalisation, for approximately 120 million poor and vulnerable families as identified from the Socio-Economic and Caste Census 2011. Beneficiaries are identified by eligibility criteria and issued a PMJAY golden card.

What PMJAY covers for oxygen therapy

PMJAY is an inpatient-hospitalisation scheme. The core coverage is:

• Inpatient oxygen as part of secondary or tertiary admission package (ICU, pulmonology, internal medicine admission) is covered, up to the per-family annual ceiling.
• Treatment packages for COPD exacerbations, pneumonia requiring oxygen support, pulmonary embolism, and similar indications are defined in the Health Benefit Package (HBP) and include oxygen as part of the inpatient treatment.

PMJAY does not, by default, cover home oxygen concentrator rental or purchase. Outpatient durable medical equipment is outside the scheme’s scope in its standard form. A beneficiary discharged from a PMJAY admission with a recommendation for home oxygen therapy typically does not get the home equipment through PMJAY, though the state in which the patient resides may have a parallel state scheme that covers the outpatient equipment (see next section).

Some states have extended PMJAY coverage to include certain outpatient services under state branding; beneficiaries should verify the exact package structure with the state agency.

Documentation

• PMJAY golden card of the beneficiary or family.
• Empanelled hospital for admission; the hospital handles cashless processing directly with the PMJAY authority.
• Discharge summary and, for any reimbursable outpatient follow-up that is scheme-covered, the prescription and bills as specified by the implementing agency.

State schemes

Several states operate independent or complementary health-insurance schemes alongside PMJAY. Coverage for home oxygen therapy varies meaningfully by state.

Rajasthan Mukhyamantri Chiranjeevi Yojana (and successor schemes)

Rajasthan’s flagship scheme has provided inpatient and certain outpatient coverage for the state’s residents, with a state-defined benefit package running alongside PMJAY. Coverage for oxygen therapy includes inpatient admission packages similar to PMJAY. Coverage of outpatient durable medical equipment (including home oxygen concentrators) has evolved across scheme iterations; the specifics at any given time should be verified with the current state implementing agency. Rajasthan’s scheme has historically been more generous on outpatient coverage than PMJAY alone.

Tamil Nadu Chief Minister’s Comprehensive Health Insurance Scheme (CMCHIS)

Tamil Nadu’s scheme covers around 16 million families with up to ₹5 lakh per family per year for secondary and tertiary hospitalisation, similar in scope to PMJAY. Coverage for oxygen therapy mirrors PMJAY — inpatient admissions fully covered, outpatient equipment outside core coverage but with some benefit packages that extend to assistive devices for specific indications. The Tamil Nadu state cancer schemes include more generous outpatient supportive-care coverage than general CMCHIS.

Karnataka Arogya Karnataka

Karnataka’s scheme blends PMJAY coverage with state-augmented benefits, with implementation through Suvarna Arogya Suraksha Trust. The scheme covers inpatient admission packages for respiratory illness and oxygen therapy in hospital. Home oxygen equipment is generally outside the core scheme but may be accessible through specific state welfare programmes (for example, Palliative Care schemes in select districts, and disability-pension-linked equipment assistance).

Other states

Telangana (Aarogyasri), Andhra Pradesh (YSR Aarogyasri), Kerala (Karunya Arogya Suraksha Padhathi), Maharashtra (Mahatma Jyotiba Phule Jan Arogya Yojana), West Bengal (Swasthya Sathi), and others operate parallel schemes with differing coverage structures. The uniform feature across schemes is that inpatient oxygen therapy is covered; the divergent feature is whether home oxygen equipment is included, excluded, or covered only under a narrow sub-benefit. Any beneficiary of a state scheme considering home oxygen therapy should request a specific benefit-package verification from the scheme implementing agency before purchasing equipment.

Private health insurance

Private health insurance — the mediclaim policies from Indian general insurers and the health-specialist insurers — is where the exclusions are most unambiguous. The industry-standard exclusion language, in various wordings across policies, covers:

“Cost of non-medical items such as durable medical equipment for home use, including but not limited to oxygen concentrators, CPAP/BiPAP devices, wheelchairs, commodes, walkers, nebulisers, and related accessories; cost of consumables used for extended home therapy; and cost of outpatient therapy not forming part of an inpatient admission.”

The implication: a typical private health policy pays for in-hospital oxygen and for the CPAP trial night during an inpatient sleep study, but does not pay for the home concentrator rental or the CPAP machine the patient buys after discharge. The home equipment, even when medically necessary and prescribed by the treating specialist, sits outside the indemnity coverage.

Three qualifications matter:

1. Some premium health policies include a “home medical equipment” or “durable medical equipment” rider. These are relatively rare, usually priced at a meaningful premium over a base policy, and typically have sub-limits within the overall sum insured. A policyholder considering this rider should read the specific language for oxygen concentrator inclusion and any caps on rental duration or purchase price.
2. Hospital-linked post-discharge coverage. Some policies cover post-discharge medical equipment rental for a limited window (30–60 days) when the equipment is prescribed as part of the discharge plan. This is useful for short-term post-operative oxygen needs but not for long-term LTOT.
3. Critical illness or cancer-specific policies. Coverage for certain advanced illnesses (advanced lung cancer, severe pulmonary fibrosis, certain neuromuscular disease progressions) may include outpatient palliative equipment as part of a broader illness package. The coverage is illness-specific and policy-specific.

The default assumption for an Indian patient with a standard private health policy should be: the home oxygen concentrator is out of pocket unless a specific rider or specialist policy applies. Checking the specific policy’s exclusion list is inexpensive and should be done before equipment is procured.

Decision frame for patients and families

A practical sequence for a patient newly prescribed LTOT:

1. Identify the primary coverage pool. A Central Government serving employee or pensioner defaults to CGHS. A private-sector employee below the wage ceiling defaults to ESIC. A PMJAY-eligible family (SECC 2011 identification) defaults to PMJAY. A private-policy holder should review the policy document. These pools are mutually exclusive — a CGHS beneficiary is not simultaneously PMJAY-eligible by scheme design.
2. Obtain a specialist prescription with the correct indication language. The prescription must state the clinical indication (SpO₂ threshold, gas analysis, comorbidity context), the prescribed flow rate, the expected duration, and whether the scope is rental (short-term) or purchase (long-term). Vague prescriptions get denied; specific prescriptions get approved.
3. Verify the empanelled-vendor list for your scheme. CGHS and ESIC maintain empanelled vendor lists. Buying from a non-empanelled vendor — even if the equipment is identical and the price is better — is a common cause of claim denial.
4. Submit the claim promptly. Most schemes have time limits for reimbursement claim submission, typically 30–90 days from purchase. Delayed submissions are denied on procedural grounds even when the underlying claim was valid.
5. For non-covered out-of-pocket costs, consider rental-first. A three-month concentrator rental at ₹2,500–4,500 per month lets a patient confirm the therapy is tolerated and the prescription is correct before committing to purchase. If the therapy is confirmed and the patient is CGHS or ESIC covered, the rental-to-purchase transition is smoother than purchasing first and seeking retrospective coverage.

Consult your treating pulmonologist and, independently, the relevant scheme’s reimbursement help desk or beneficiary relations office before equipment is purchased. The reimbursement landscape is scheme-specific and the specifics matter more than the general rules.

Closing

The reimbursement map for Indian home oxygen therapy is legible, but it is not publicly consolidated. CGHS and ESIC cover the equipment substantively for their beneficiaries, with documented empanelled-vendor and reimbursement processes that work when followed. PMJAY covers the inpatient episode in full but not the outpatient equipment. State schemes vary on outpatient coverage; the specific state’s benefit package must be verified. Private health insurance, the default pool for middle-income salaried households, typically does not cover the equipment at all.

A patient who understands which pool they are in, obtains the right prescription language, and buys from the right vendor can recover a substantial fraction of the cost. A patient who does not typically pays full price. The arithmetic for a COPD patient on 5 LPM continuous therapy — concentrator purchase ₹35,000–55,000, annual servicing ₹3,000–6,000, cylinder backup and refills ₹8,000–20,000 — matters. The scheme paperwork is unpleasant, but it is not complicated; it is substantially cheaper to navigate the paperwork than to fund the equipment out of pocket over the multi-year horizon of LTOT. The patient’s family, or a dedicated relative willing to handle the paperwork, is typically the right resource — the treating pulmonology team is not set up to file reimbursement forms and should not be expected to.
