Health Insurance Claim Denied in Ukraine: Guide

Ukraine's health insurance landscape differs significantly from the mandatory social insurance models of Western and Central Europe. Ukraine does not yet have a comprehensive mandatory health insurance system — the country relies primarily on a budget-funded public health network (Programa medychnykh harantiy — the Medical Guarantee Program, introduced under health reform since 2018) alongside a private insurance market. If your private health insurer has denied a claim, this guide covers your rights and the appeal process.

Health Insurance in Ukraine

Ukraine's public healthcare reform, implemented from 2018 onwards, introduced a system where the National Health Service of Ukraine (NHSU — Natsionalna sluzhba zdorovia Ukrainy) purchases a defined basket of medical services from contracted public and private providers on behalf of all citizens. Ukrainians can register with a family doctor under the eHealth system and access a defined set of primary and secondary care services covered by the state. However, this system does not function as comprehensive insurance in the traditional sense — significant gaps exist in specialty care, pharmaceuticals, and hospital services.

Private health insurance fills a major role in Ukraine, particularly for corporate employees whose employers provide group health insurance as a benefit. The leading private health insurers in Ukraine include:

ARX (formerly AXA Ukraine, rebranded following the sale by AXA Group), one of the largest and most recognised private health insurers in Ukraine, offering individual and corporate health insurance, life, motor, and property products.

INGO Ukraine — part of a major Ukrainian insurance holding group, active in life, health, property, and cargo insurance.

TAS Insurance Group — a large Ukrainian-owned insurance conglomerate with significant health insurance operations.

PZU Ukraine — the Ukrainian arm of PZU Group, the largest Polish insurer, active in health and property insurance in Ukraine.

Ukrainian Insurance Alliance (UAS) and other domestic insurers also operate in the health segment.

Regulatory Context

Insurance supervision in Ukraine is primarily the responsibility of the NBU (Natsionalnyi bank Ukrainy — National Bank of Ukraine), which assumed consolidated financial sector regulatory authority in 2020, taking over from the former National Commission for State Regulation of Financial Services Markets (Natskomfinposluh). The NBU's Financial Sector Consumer Protection Department handles policyholder complaints.

The ongoing wartime context (following Russia's full-scale invasion in February 2022) has significantly affected the Ukrainian insurance market. Some regions are inaccessible for policy purposes; property and specialty insurance products have been affected by war exclusion clauses; and some insurers have faced solvency pressures. Health insurance has generally continued to operate in government-controlled regions, but policyholders should be aware of potential force majeure and war exclusion provisions in their contracts.

Common Reasons Private Health Insurers Deny Claims in Ukraine

Network restrictions. Ukrainian corporate health policies typically have contracted provider networks (likuvalni zaklady — treatment facilities). Treatment at facilities outside the network — even reputable private clinics — results in zero or reduced reimbursement.

Pre-authorization not obtained. Most Ukrainian private health insurers require advance authorization for planned hospitalisation, specialist consultations above a threshold, and certain diagnostics. Claims submitted without this step are denied.

Condition excluded or waiting period not completed. Pre-existing condition exclusions and waiting periods are standard in Ukrainian private health policies. Claims for conditions that pre-date the policy or arise during the initial waiting period are automatically rejected.

Documentation requirements. Ukrainian insurers require specific documentation formats — original invoices (chek or kvytantsia), signed medical reports (medychna dovidka), discharge summaries (vypyska z istorii khvoroby), and referrals. Claims submitted without complete documentation are declined on technical grounds.

War exclusion clauses. Post-2022, some insurers have applied war exclusion clauses to deny health claims where the injury or illness can be connected to war-related circumstances. These denials are often the most contested.

How to Appeal a Denied Claim in Ukraine

Step 1 — Request the written denial. Ukrainian insurers must provide a written explanation for denied claims. Request this if it was not automatically provided, specifying the policy clause cited.

Step 2 — Internal complaint. Submit a formal written complaint (zvernennia) to your insurer's customer service or complaints department. Under Ukrainian insurance law, insurers must respond within a defined period (generally 30 days).

Step 3 — NBU complaint. If the internal response is inadequate, file a complaint with the NBU's consumer protection unit at bank.gov.ua. The NBU can investigate whether the insurer acted in compliance with Ukrainian insurance legislation.

Step 4 — Court proceedings. Ukrainian civil courts (mistsevyi zahalnyi sud — local general courts) adjudicate insurance contract disputes. For complex cases, legal representation is advisable.

Practical Tips for Ukrainian Policyholders

• Keep the 24-hour assistance number for your insurer saved — most Ukrainian corporate health policies require you to call the assistance line before seeking treatment, not after.
• Document all treatments with original receipts and medical reports, even for routine consultations.
• If your employer provides your health policy, your HR department may have a direct contact with the insurer to resolve disputes faster.
• For war-related insurance disputes, INGO and ARX both have dedicated procedures — consult the insurer directly and escalate to the NBU if necessary.
