Lists of medical billing companies in the Philippines are easy to find and hard to trust. Most are written by vendors who place themselves first, and almost none separate what a company has proven from what it merely says about itself. This guide takes a different approach. Every claim below is tied to a source we actually retrieved on 8 August 2026, and each provider entry is labelled by evidence type: press coverage carries more weight, company pages are marked as self-attested. The providers appear alphabetically. This is a verified list, not a ranking, because no public data we reviewed supports ordering these firms by quality.

What Medical Billing Outsourcing to the Philippines Involves

Medical billing sits inside the wider discipline of revenue cycle management, the process that runs from patient scheduling to final payment. Philippine delivery teams typically handle front-end work such as eligibility verification and prior authorization, mid-cycle tasks such as medical coding and charge entry, and back-end functions such as denial management, remittance posting, and accounts receivable follow-up. Access Healthcare's own service breakdown illustrates the full span, from scheduling and eligibility through coding and clinical documentation to denial management and collections.

One point buyers should fix in mind before reading any vendor page: there is no official HIPAA certification. HIPAA is a United States statute, and no US agency certifies BPO firms against it. Every "HIPAA compliant" or "HIPAA certified" statement on a vendor website is a self-attestation until the vendor shows third-party evidence such as a SOC 2 report or signs a business associate agreement. We therefore label all HIPAA claims below as self-attested.

Providers With Verifiable Evidence, Listed Alphabetically

Inclusion here required at least one source we could retrieve and check ourselves, either press coverage or the company's own published pages. Self-attested items are labelled with the retrieval date. For a wider pool filtered by PEZA classification and certification status, the BPO directory lists Philippine providers by service vertical, including medical billing and healthcare information management.

Access Healthcare

A revenue cycle specialist headquartered in Dallas with a significant Philippine footprint. Its locations page lists four Philippine delivery sites across Pasay and Taguig, including One World Square and Venice Corporate Center at McKinley Hill Cyberpark and Double Dragon Center West in the Bay Area, alongside centers in the United States and India (self-attested as of 8 August 2026). Services cover the full revenue cycle, from eligibility and prior authorization to coding, denial management, and accounts receivable.

Connext Global Solutions

A dedicated-staffing provider where the client retains operational control of the billing team. On its healthcare page, Connext describes medical billing, eligibility verification, and patient support services, and states that it is HIPAA compliant and SOC 2 certified with a 98 percent client retention rate (self-attested as of 8 August 2026).

Infinit-O

A Manila-based outsourcing firm whose healthcare practice covers end-to-end revenue cycle management from patient registration to final payment, medical billing, and claims and denial management. The page displays a Certified B Corp badge and a National Privacy Commission Seal of Registration, and refers to HIPAA-compliant support (self-attested as of 8 August 2026).

Magellan Solutions

One of the longer-running Filipino-owned BPOs. Its company overview states SEC registration in 2003, operations from August 2005, headquarters in Mandaluyong City, and around 1,000 seats of capacity. The firm states it holds ISO 27001:2013 certification issued through Bureau Veritas and describes itself as HIPAA compliant, with medical billing and coding among its services (self-attested as of 8 August 2026). Buyers should ask which version of the ISO 27001 standard the current certificate covers and confirm it in a registry, as explained below.

MicroSourcing

A large managed-operations provider affiliated with Australia's Probe Group. Its healthcare page lists medical billers, medical coders, insurance verification officers, and revenue cycle analysts among the roles it staffs, and states ISO 27001 and ISO 9001 certifications. Notably, MicroSourcing describes HIPAA-aligned environments rather than claiming certification, a more precise wording than most competitors use (self-attested as of 8 August 2026).

Omega Healthcare

The entry with the strongest third-party evidence. Manila Times coverage from March 2026 reports that Omega grew its Philippine workforce from 2,200 employees in 2024 to 3,000 in 2025, plans to expand to 4,000 to 5,000 in 2026 across Manila and Cebu delivery centers, and is scaling hiring of US-registered nurses for non-bedside clinical work such as documentation, authorization support, and appeals. The same coverage notes Omega received the Katapatan Award from the Healthcare Information Management Association of the Philippines.

How to Verify a Provider Yourself

Three checks take under an hour and filter out most weak claims.

  • Corporate registration. Confirm the legal entity through the Philippine SEC. According to a Philippine law firm's verification guide, the eSPARC company search returns the registered name, SEC registration number, incorporation date, and status, the SEC CheckApp mirrors the database and flags entities under enforcement action, and SEC Express can supply the General Information Sheet listing current directors and officers.
  • PEZA status. PEZA registration signals an export-oriented operation located in an accredited IT park or building. Per a corporate services firm's summary, registered enterprises receive income tax holidays of four to eight years followed by a 5 percent tax on gross income, and registration requires SEC documents and board approval. Ask the vendor for its PEZA certificate of registration rather than taking a logo on the website at face value.
  • ISO 27001. Never accept a certificate PDF alone. The IAF CertSearch database, run by the International Accreditation Forum, held over 1.1 million accredited certificates from 1,342 certification bodies and 74 accreditation bodies as of its 2023 launch coverage, and it is free to search. If a vendor's ISO 27001 certificate does not appear there, ask the certification body directly.

For HIPAA, request a signed business associate agreement and any third-party attestation the vendor holds. If you are building an internal checklist for vendor due diligence, the AI Academy covers evaluation frameworks for outsourcing buyers in more depth.

Market Context for 2026 Buyers

The sector behind these companies is growing. Philstar reported in January 2026 that Philippine IT-BPM revenue passed 40 billion US dollars in 2025, up from 38 billion in 2024, with employment reaching 1.9 million and the industry association IBPAP naming healthcare among the key growth drivers. The 2026 baseline target is 42 billion dollars and 1.97 million workers. The healthcare segment has its own trade body: HIMAP, founded in 2003 as the Medical Transcription Industry Association of the Philippines and renamed in 2015 as its scope widened to clinical support and healthcare IT services.

For buyers, the practical readings are straightforward. Capacity is expanding, clinical and billing talent is deepening beyond voice work, and providers with registry-verifiable credentials are easier to separate from the rest than they were even two years ago. We track sector developments as they land in our industry news feed, and we will revisit this list as new registry data and press coverage emerge.
