Three central-government health schemes cover most of the white-collar reimbursement universe for home oxygen and home NIV in India: CGHS (Central Government Health Scheme) for serving and retired civilian employees, ECHS (Ex-Servicemen Contributory Health Scheme) for ex-defence personnel and dependants, and ESIC (Employees’ State Insurance Corporation) for organised-sector workers below a wage ceiling. The schemes look superficially similar — each pays for medically necessary durable medical equipment (DME) under a rate list — but the documentation pathways, ceilings, empanelment rules, and rejection patterns diverge enough to break a claim if you treat them as one thing. This guide walks through the three schemes side by side, with the focus on home oxygen concentrators and bilevel/CPAP devices.
The three schemes, compared on what matters for DME
CGHS is the largest of the three and applies to central-government civilian employees, pensioners, MPs, judges, and a handful of autonomous-body staff in CGHS-covered cities. It runs a published rate list for both procedures and durable equipment, updated periodically by the Ministry of Health & Family Welfare. Reimbursement is either cashless through empanelled hospitals and DME suppliers, or post-payment with a claim submitted to the relevant CGHS Wellness Centre and Additional Director.
ECHS mirrors CGHS structurally for ex-servicemen and is administered by the Department of Ex-Servicemen Welfare under the Ministry of Defence. The rate list largely tracks CGHS with periodic alignment, but the empanelment universe is its own — ECHS polyclinics and ECHS-empanelled hospitals/DME providers are the cashless route. Out-of-network purchase is reimbursable but at the same rate ceiling, and the documentation chain runs through the parent polyclinic.
ESIC covers a different population: organised-sector employees with wages under the notified ceiling, and is run by an autonomous corporation under the Ministry of Labour & Employment. ESIC owns and runs its own hospitals and dispensaries; DME for home use is typically issued in kind from an ESIC facility rather than reimbursed against a private purchase. Where in-kind issue is unavailable, reimbursement is at the ESIC rate, which is usually the lowest of the three. (ESIC)
What the rate lists actually pay for home respiratory DME
Indicative ceilings, drawn from the most recent published rate lists and the typical interpretation by sanctioning authorities:
- 5 LPM oxygen concentrator: CGHS ceiling broadly in the ₹40,000–₹55,000 band; ECHS aligned; ESIC lower, often ₹35,000–₹45,000.
- 10 LPM oxygen concentrator: CGHS ceiling broadly ₹85,000–₹1,10,000; ECHS aligned; ESIC less consistently covered, often requiring case-by-case sanction.
- BiPAP-S (bilevel-spontaneous): CGHS ceiling broadly ₹65,000–₹90,000.
- BiPAP-ST (with backup rate): ₹1,10,000–₹1,40,000 typical sanctioned range, frequently requiring AIIMS or empanelled-tertiary specialist letter.
- CPAP (fixed or auto): ₹35,000–₹55,000 typical sanctioned range, with strong preference for AHI-documented severity above 30/hr.
- Humidifier, mask, tubing replacement: Treated as consumables; usually reimbursed annually within a smaller envelope. (CGHS)
These are working ranges. The published rate list is the authoritative source for the date of your claim, and the ceiling does occasionally shift on revision — the GST treatment, however, is structural and discussed below.
Prescription requirements that pass without a query
A reimbursement file rejected on prescription deficit is the most common avoidable failure. Across all three schemes the assembly looks similar:
- Specialist prescription on letterhead. A pulmonologist or, in defence, a Service Hospital specialist. The prescription must name the device class (concentrator vs cylinder, CPAP vs BiPAP, BiPAP-S vs BiPAP-ST), the prescribed flow rate or pressure, the duration of use per day, and the expected duration of therapy.
- Documented hypoxaemia for oxygen claims. SpO₂ on room air recorded over time, ideally with at least one resting reading below 88% and ideally one ABG showing PaO₂ < 55 mmHg or PaO₂ 55–60 mmHg with cor pulmonale or polycythemia. The ICMR and Indian Chest Society LTOT criteria are well aligned with the global GOLD criteria here. (ICMR)
- Documented sleep-disordered breathing for BiPAP/CPAP claims. A polysomnography report with AHI breakdown (obstructive, central, mixed), titrated pressure, and where relevant a daytime hypercapnia documentation (ABG with PaCO₂).
- CGHS / ECHS Form — the relevant Annexure for DME sanction, signed by the patient, countersigned by the CMO of the Wellness Centre or polyclinic.
- Quotation on supplier letterhead with model number, GSTIN of the supplier, GST rate, HSN code (9019 for most respiratory devices), and the price split into base and tax.
For ESIC, the equivalent assembly runs through the IMO at the dispensary or ESIC hospital outpatient, with the specialist letter ideally from an ESIC or government tertiary facility.
Empanelled-dealer route vs reimbursement-after-purchase
CGHS and ECHS both maintain lists of empanelled DME suppliers. Buying from one usually allows a cashless transaction or credit arrangement with the scheme directly settling against the rate list. The patient pays only the difference between the supplier’s offered price and the rate-list ceiling, if any.
The reimbursement-after-purchase route is the alternative: the patient buys the device from any GST-registered supplier, then submits the claim to the sanctioning authority. The reimbursable amount is capped at the rate list — not the invoice — so an out-of-list purchase at ₹65,000 against a ₹50,000 ceiling pays back ₹50,000 at most, and only on full file completeness.
The practical implication: if the scheme is CGHS or ECHS and the city has an empanelled supplier with a current sanction in place, the cashless route is faster, lighter on paperwork, and avoids the float on the patient. If the patient is in a Tier-2/3 city or if the empanelled list does not include a model the prescribing specialist insists on, the post-purchase route is the right answer — but the file must be assembled tightly.
GST treatment — the trap that catches most claims
Most respiratory devices fall under HSN 9019 and attract GST at 12%. Some accessories and consumables sit at 18%. The reimbursement schemes do not pay GST as a separate addition on top of the rate-list ceiling — the ceiling is treated as the all-inclusive price, with GST presumed embedded.
Two consequences:
- An out-of-list dealer who ships without a GST-compliant tax invoice (no GSTIN, no tax breakup, no HSN) breaks the file. CGHS and ECHS will reject the claim. ESIC will reject and may flag the supplier.
- A supplier who quotes “₹50,000 + 12% GST extra” on a device whose rate-list ceiling is ₹50,000 is asking the patient to absorb the GST. The patient should either negotiate the inclusive price or buy from an empanelled supplier at the listed ceiling.
The cleanest invoice format reads: Base ₹X, CGST ₹Y, SGST ₹Y (or IGST for inter-state), with a single all-inclusive total. The HSN must read 9019 for the primary device. The supplier’s GSTIN must be active at the date of invoice — verifiable on the GST portal — and the buyer’s name on the invoice must match the scheme card name precisely.
Private health insurance — for context
Private indemnity policies in the Indian retail market are inconsistent on home DME. The standard Mediclaim policy covers oxygen and ventilation as part of an inpatient admission. Home oxygen and home BiPAP after discharge are typically covered only if a domiciliary hospitalisation clause was triggered or if the policy carries a specific home-care rider. Cashless on home DME is rare; reimbursement is at policy schedule rather than CGHS rate. The IRDAI has periodically pushed insurers toward home-care coverage but the practical experience in 2026 remains lottery. (IRDAI)
For patients who hold both CGHS/ECHS coverage and a private policy, CGHS/ECHS is invariably the better claim path for home DME — the rate list is published, the file structure is standardised, and the reimbursement universe is broader than what private policies allow on outpatient home equipment.
Assembling a complete reimbursement file
The minimum viable file, in order:
- Specialist prescription on letterhead with diagnosis, device class, settings, duration of therapy, signed and stamped.
- ABG / SpO₂ trend report (oxygen claims) or PSG with titration (CPAP/BiPAP claims).
- CGHS / ECHS sanction form, countersigned by Wellness Centre / polyclinic CMO.
- Pre-purchase quotation from supplier on letterhead with GSTIN, HSN, model number, all-inclusive price.
- GST tax invoice on purchase, matching quotation, with serial number of unit and warranty card.
- Bank details and cancelled cheque for direct credit of reimbursement.
- Photocopy of CGHS / ECHS / ESIC card and Aadhaar.
- Duly filled claim form (Annexure as applicable).
Keep two copies of every document, retain originals where the scheme requires originals, and submit through the correct route (Wellness Centre for CGHS; polyclinic for ECHS; dispensary or ESIC office for ESIC).
Typical processing time and rejection causes
Processing time on a clean file: CGHS 30–60 days, ECHS 45–90 days, ESIC 30–75 days. Files that go to a higher sanctioning authority — for high-value items, BiPAP-ST, AVAPS, and 10 LPM concentrators above ceiling — can run 90–180 days.
The recurring rejection causes:
- Specialist prescription that does not name device class or settings.
- Missing ABG or SpO₂ documentation for oxygen claims.
- Quotation and tax invoice mismatch on price, model, or GSTIN.
- Supplier GSTIN inactive, suspended, or in a different state from the supply route on the invoice.
- HSN code on invoice not matching 9019 for the primary device.
- Sanction form unsigned by the CMO.
- Original prescription and copies submitted in wrong order, or on multiple letterheads.
A file that fails on any of these can usually be rebuilt and resubmitted, but the clock restarts and the patient carries the float in the interim. The cleanest path — for a first-time CGHS/ECHS claim on home oxygen or BiPAP — is the empanelled-supplier cashless route, accepted by the local Wellness Centre, with the post-purchase reimbursement file held in reserve only when no empanelled option exists.
