Pre-authorisation is the process by which a network hospital obtains approval from your insurer before charging your policy for a cashless stay. For the patient, it is largely invisible — the hospital manages it. But when it breaks down (delays, partial approvals, enhancement queries, denials), you need to understand how to intervene.


Who Is Involved in Pre-Authorisation

PartyRole
Policyholder / patientPresents health card and ID at admission; provides consent for insurer to access medical details
Hospital’s insurance deskSubmits the pre-auth request form with diagnosis, treatment plan, expected cost, and patient’s policy details
TPA (Third Party Administrator)Receives the pre-auth from hospital; verifies policy coverage, waiting periods, limits; issues approval or queries
InsurerUltimately responsible; TPA acts on insurer’s authority as per tariff agreement

Planned Hospitalisation: Pre-Auth Process

For surgeries, procedures, and scheduled admissions:

Step 1: Confirm Network Hospital

Verify the hospital is in your insurer’s cashless network — the insurer’s website lists empanelled hospitals by city or pin code. Call the hospital’s insurance desk before booking to confirm the insurer is active (networks are periodically updated).

Step 2: Hospital Submits Pre-Auth Request (3–5 days before admission)

The hospital insurance desk sends to the TPA:

  • Patient’s insurance details (policy number, health card)
  • Confirmation of identity (Aadhaar or equivalent)
  • Treating doctor’s details and proposed admission date
  • Provisional diagnosis and ICD-10 code
  • Proposed procedure / surgery (CPT code where applicable)
  • Estimated cost breakdown (room, surgery, anaesthesia, consumables, medicines)

Step 3: TPA Reviews Eligibility

The TPA checks:

  • Policy is active and in force
  • Insured is within the coverage period
  • Waiting periods for the diagnosed condition have elapsed
  • Sum insured available (remaining after any prior claims)
  • Any applicable sub-limits or room rent caps
  • Pre-existing disease status of the condition

Step 4: Approval Letter Issued

The TPA issues a pre-auth approval letter to the hospital specifying:

  • Approved amount
  • Approved room category (tied to room rent limit in policy)
  • Approved procedure / diagnosis
  • Validity period of the approval

If the room category implied by the approved room rent is lower than desired, you can negotiate with the hospital — but any excess room cost will be borne by you.


Emergency Hospitalisation: Pre-Auth Process

For emergency admissions (accident, acute medical event), the sequence is reversed:

  1. Admission first — patient is admitted based on medical need
  2. Notification within 24 hours — the hospital must notify the TPA within 24 hours of admission
  3. TPA issues emergency pre-auth — based on available information; may be provisional
  4. Documentation follows — full documentation submitted by hospital within 48–72 hours
  5. Final approval issued; differential costs during undocumented window may be reviewed

IRDAI 2024 circular on timelines:

  • Emergency pre-auth: TPA must respond within 1 hour of notification
  • If the TPA fails to respond within 1 hour, the hospital can proceed with treatment and the insurer cannot reject on pre-auth delay grounds

Partial Pre-Authorisation: What It Means

A partial approval occurs when the TPA approves less than the expected cost. This is common and does not mean the rest will be rejected.

Typical reasons for partial approval:

  • Room rent limit lower than the requested room category
  • Sub-limits on specific procedures (e.g., cataract cap, knee replacement cap)
  • Only the base procedure approved; optional procedures pending separate auth
  • Consumables excluded (IRDAI non-payable list)

What to do with a partial approval:

  1. Ask the hospital’s insurance desk for a breakdown of what was approved vs excluded
  2. Decide whether to proceed at the approved room category (lower room cost) or upgrade and self-fund the difference
  3. For large gaps, call the insurer’s helpline directly — some approvals can be enhanced if additional clinical information is provided

Enhancement Queries: During the Hospitalisation

If your condition requires more treatment than initially anticipated, the hospital must seek a coverage enhancement from the TPA.

Common triggers for enhancement queries:

  • Total bill exceeding originally approved amount by a material margin
  • New diagnosis identified during the stay (e.g., post-surgical complication)
  • ICU admission not in the original approval
  • Extended hospital stay beyond the approved duration
  • Additional surgery or procedure

The enhancement process:

  1. Hospital insurance desk sends an enhancement request with updated clinical notes
  2. TPA reviews and responds (same 1-hour IRDAI deadline applies)
  3. Enhancement is approved, partially approved, or denied

If enhancement is denied, the excess amount above the original approval is your responsibility. The insurer will typically settle the original approved amount; you pay the rest.


Pre-Auth Denial: Your Options

If the TPA denies the pre-authorisation request:

ActionDetails
Understand the specific reasonInsurer must cite the policy clause in writing
Call the insurer’s claims helplineSome denials are reversed with additional clinical information
Request emergency escalationAsk the TPA for escalation to senior reviewer if clinically urgent
Pay and file reimbursementA reimbursement claim is a separate decision — denial of pre-auth is not a final claim rejection
File grievance after dischargeIf the reimbursement is also rejected, follow the four-stage escalation process

Note: The most common pre-auth denial reasons — PED waiting period violations, non-network hospital errors, or missing policy details — can often be addressed on the same day if caught early.


Documents the Hospital Insurance Desk Needs From You

Bring these to every planned admission:

  • Original health insurance card (physical or digital via insurer app)
  • Government-issued photo ID (Aadhaar, PAN, passport)
  • Copy of the health insurance policy (first page)
  • Doctor’s referral / appointment letter (for planned procedures)
  • Pre-test reports referenced in the treatment plan

Frequently Asked Questions

What is pre-authorisation in health insurance?
Pre-authorisation (pre-auth) is the approval the hospital obtains from your insurer or its TPA before proceeding with an approved cashless claim. The hospital submits your diagnosis, treatment plan, and expected costs. The TPA verifies your coverage, checks waiting periods, applies applicable limits, and issues a cashless approval letter with an approved amount. Treatment begins (or continues) after this approval.
How long does pre-authorisation take in India?
Under IRDAI's 2024 circular on cashless claims, insurers must issue pre-auth decisions within 1 hour of receiving complete documents for both planned and emergency admissions. If additional information is needed, the insurer must request it within 30 minutes. Delays beyond these limits should be escalated. In practice, straightforward claims at well-known hospitals are typically approved in 30–45 minutes.
What is an enhancement query in cashless hospitalisation?
An enhancement query is a formal request from the TPA to the hospital asking for additional information or approval extension during the course of hospitalisation. Common triggers include: treatment costs exceeding the initially approved amount, new diagnoses identified during the stay, ICU admission not included in the original approval, or extended hospitalisation beyond the approved duration. The hospital must respond to enhancement queries within 4 hours to prevent disruption to the approval.
What happens if pre-authorisation is denied?
If cashless pre-auth is denied, the insurer must provide a written reason citing the specific policy clause. You have two options: (1) pay the bill out-of-pocket and file a reimbursement claim, which is a separate decision process from the pre-auth denial; or (2) call the insurer's claims helpline immediately to understand if the denial can be resolved (e.g., a missing document) before treatment commences. A pre-auth denial does not permanently bar a reimbursement claim on the same admission.
Does cashless pre-auth need to be obtained before admission?
For planned hospitalisations, pre-auth should ideally be requested 3–5 days before the admission date. For emergency admissions, the hospital is required to submit the pre-auth request within 24 hours of admission. Pre-auth is obtained by the hospital (not you) — you need to present your health card and valid ID at the hospital's insurance desk.
