Methodology

The free grade on this page contains zero zReports judgment: it maps the state's own published licensing and enforcement verdicts through one fixed rule, applied identically to every surgery center in America. Where the record and public reputation diverge, a highly reviewed facility with serious findings on file, the paid Consumer Intelligence Report™ surfaces it through the composite Consumer Z Score™ and our published ten point methodology. Facilities are never contacted and cannot pay to change a score. Read the full methodology →

About surgery center licensing in Maine

Outpatient Surgery Centers in Maine are overseen by the Centers for Medicare & Medicaid Services (CMS), whose certification, inspection, and quality-reporting data is published on the public record. This page is computed from CMS Ambulatory Surgical Center Quality Reporting data, the government’s own filings, not reviews or advertising.

Frequently asked questions

How many surgery centers are there in Maine?

Maine has 15 active licensed surgery centers on the state's public file, across 8 cities. Every one has a free records layer grade on zReports.

Which Maine city has the most surgery centers?

Portland, with 5 licensed surgery centers, followed by Bangor (3) and Presque Isle (2).

How are Maine surgery center grades calculated?

The free records layer grade contains zero zReports judgment. It maps the government's own published verdicts, CMS Ambulatory Surgical Center Quality Reporting data, through one fixed rule, applied identically to every surgery center in the country. The paid Consumer Intelligence Report™ adds the composite Consumer Z Score™, which audits the record against public reputation through our published ten point methodology.

Why can a facility with 5-star reviews have a low grade?

Reviews and records are different surfaces. Reviews reflect what visitors chose to write, and can be managed by the business. Inspection and enforcement records are filed by the state, are mandatory, and cannot be edited by the facility. When the two diverge, the record is the surface worth checking. That divergence is exactly what zReports was built to surface.

How often are these rankings updated?

Rankings refresh whenever Maine republishes its licensing data; facility pages carry the records-verified date for each provider. This page was generated from the current file as of October 2026.

Can a facility pay to change its score?

No. Facilities are never contacted, never notified, and cannot pay to be listed, delisted, or re-scored. zReports has no business relationship with any facility it grades, independence is the product.

Data Provenance

This report was generated from the zReports Consumer Records Database™, a continuously updated database that normalizes official government licensing, inspection, enforcement, ownership, and safety records across multiple federal and state agencies. Every statistic in this report is traceable to its originating public record. Facilities cannot pay to alter scores, rankings, or findings.
