Yes—California ASCs are accepting site-of-service reimbursement cuts of $680–$2,400 per procedure they could fight because commercial payers downgrade ASC facility fees to hospital outpatient rates, apply arbitrary “site neutrality” policies without contract language supporting them, and deny implant pass-through costs claiming procedures should transfer to physician offices when ASC contracts explicitly guarantee higher facility fee structures.
Most California ASCs lose $180,000–$420,000 per 12 months accepting site-of-service reimbursement downgrades without reviewing actual contract terms or challenging payer policies lacking contractual foundation.
The Contract Review That Reveals Everything
Pull your three largest commercial payer contracts. Search for “facility fee,” “site of service,” and “ASC rate.”
Compare contracted ASC facility fee rates against your latest remittance advice showing actual payments received.
Table 1: Site-of-Service Reimbursement Reality Check
| What Contract Says | What Payer Actually Pays | The Gap |
| ASC facility fee $2,800 | Hospital outpatient rate $1,400 | Lost $1,400 |
| Implant pass-through 100% | “Bundled in procedure” denial | Lost $1,200 |
| ASC-specific fee schedule | Physician office rate $680 | Lost $2,120 |
If actual payments are 40–60% below contracted rates, you’re accepting site-of-service reimbursement cuts without contract justification.
Three Site-of-Service Reimbursement Cuts California ASCs Accept Without Fighting
Cut 1: “Site Neutrality” Applied Without Contract Language
Blue Shield sends remittance showing facility fee reduced from contracted $2,800 to $1,400 with explanation: “Site neutrality adjustment—procedure payable at hospital outpatient rate.”
You accept the $1,400 payment assuming “site neutrality” is standard policy. But your contract contains zero mention of site neutrality provisions. The agreement explicitly states: “ASC facility fees per attached fee schedule” showing $2,800 for the procedure code.
Payers apply site-of-service reimbursement downgrades hoping ASCs won’t review contracts and challenge unauthorized adjustments. For California ASCs performing 120 monthly procedures with $1,400 unauthorized downgrades, that’s $168,000 accepted per 12 months without contract support.
The appeal that works: “Per Section 4.2 of our contract dated [date], ASC facility fees are payable per attached fee schedule showing [procedure code] at $2,800. Payment of $1,400 violates contracted rates. No site neutrality provision exists in our agreement. Request reprocessing to contracted amount: $2,800.”
ASC Billing Services specializing in contract enforcement recover $168,000 per 12 months from unauthorized site-of-service reimbursement downgrades lacking contractual basis.
Cut 2: Implant Pass-Through Denied as “Bundled”
United Healthcare denies separate implant billing ($1,200) stating “bundled in procedure code—no separate reimbursement.” Your ASC accepts the denial assuming implants bundle into facility fees.
But your contract states: “Implants and devices separately reimbursed at invoice cost plus 10% handling fee.” The denial contradicts explicit contract language guaranteeing pass-through reimbursement.
California ASCs performing 45 monthly implant procedures accepting bundling denials lose $54,000 monthly—$648,000 per 12 months in site-of-service reimbursement cuts when contracts guarantee separate payment.
The contract-based appeal: “Per Section 6.1, implants are separately reimbursable at invoice cost. Attached invoice shows $1,200 device cost. Contract requires separate reimbursement. Bundling denial violates agreement terms.”
Medical Billing Services in California with ASC contract expertise recover implant pass-through denials worth $648,000 per 12 months through contract enforcement.
Cut 3: Procedures Downcoded to Physician Office Rates
Aetna pays colonoscopy at $680 (physician office rate) instead of contracted ASC facility fee $2,800. Explanation: “Procedure performed in setting not requiring ASC-level resources.”
Your ASC accepts $680 assuming payer determines appropriate setting. But your contract guarantees ASC facility fees for all procedures performed in your facility regardless of payer’s setting determination. The contract doesn’t include language allowing payer discretion on appropriate setting.
For California ASCs performing 85 monthly procedures downcoded to office rates, that’s $180,200 monthly loss—$2,162,400 per 12 months in site-of-service reimbursement cuts lacking contract authority.
ASC Billing in California specialists challenge setting-based downgrades: “Contract guarantees ASC facility fees for procedures performed in our facility. No provision allows payer to determine appropriate setting. Procedure performed in ASC per contract terms requires ASC facility fee: $2,800.”
