Lien-friendly and flexible with every physician and case
Many surgery centers turn away cases that do not fit a narrow payer profile. We take the opposite approach. DOSC works on medical liens and is built to be flexible with physicians and the realities of their caseloads — cash, commercial insurance, personal-injury liens, and select workers’-compensation cases. Please contact our billing team to confirm current insurance and Medicare participation before scheduling.
- Lien cases welcome — personal-injury and select workers’-comp cases handled on a medical lien; our billing team coordinates lien intake with your office and, where applicable, the patient’s attorney.
- Flexible arrangements — full credentialing for ongoing volume or single-case / temporary privileges for a one-off case; protected block time when you want it, open and add-on time when you don’t.
- All specialties and scenarios considered — if your outpatient case can be performed safely in an ASC, we want to make it easy to do it here. See the specialties and procedures already performed at DOSC.
- PI & attorney coordination — for injury cases, see how we work with personal-injury and lien attorneys.

Credentialing
Our Medical Staff Office manages a straightforward credentialing process for physicians seeking facility privileges at DOSC. We support full credentialing for ongoing case volume and single-case/temporary privileges where appropriate.
What we need from you
- Current CA medical license (verified via primary source)
- DEA registration (if applicable to specialty)
- Board certification documentation
- Current CV and training history
- Malpractice insurance — declarations page showing active coverage
- Peer references (typically three)
- NPDB self-query (within 180 days)
- Immunization and health clearance documentation
Timeline
Most complete applications are reviewed by our Credentials Committee within 30–45 days of receiving all required documentation. Incomplete applications extend the timeline — our MSO staff will follow up proactively if anything is missing.
Re-credentialing
Privileges are reviewed on a standard two-year cycle. We send renewal packets approximately 120 days before expiration.
Block time & scheduling
Surgeons with consistent case volume can request protected block time — recurring OR blocks reserved for your practice. Block time lets your office build around a predictable surgical day instead of hunting for open rooms.
- Dedicated blocks — half-day, full-day, or recurring weekly
- Release-to-pool policy — unused blocks released in advance open up rooms for other surgeons
- Add-on scheduling — open time available for one-off or urgent cases
- Coordinator contact — a dedicated scheduling coordinator handles your office’s bookings directly
Facility & equipment
Our ORs are configured for the range of ambulatory surgical procedures that have moved safely out of the hospital. Specific capability varies by specialty — confirm with scheduling for the equipment you’ll need.
- Operating rooms — fully equipped rooms with modern anesthesia machines, surgical lighting, and electrocautery
- Imaging — fluoroscopy (C-arm), ultrasound guidance for interventional work
- Video towers — HD arthroscopy and endoscopy platforms
- Recovery — dedicated pre-op and Phase I / Phase II PACU bays staffed by experienced RNs
- Sterile processing — on-site reprocessing with tracking
- Pharmacy & anesthesia support — credentialed anesthesia providers available
Surgical staff
Every case at DOSC is supported by a team of experienced OR nurses, certified surgical technologists, and credentialed anesthesia providers. Our staff ratio is structured to support the outpatient case mix safely and efficiently, from pre-op through discharge.
Our Medical Director oversees clinical operations and is the point of contact for any case-level or facility concerns.
Ancillary & administrative support
- Pre-op phone outreach to patients the day before surgery
- Pathology routing to the lab of your preference
- Dictation / note integration with your EMR workflow (paper or electronic)
- Implant & vendor coordination for cases requiring specialty supplies
- Billing & collections support — facility billing handled separately from professional billing; our office is happy to coordinate on insurance questions as needed
What the Credentialing and First-Case Onboarding Process Typically Looks Like
Surgeons who are new to ambulatory surgery centers sometimes find the onboarding timeline opaque, particularly if they have primarily operated in hospital settings. Here is a plain-English overview of what the process typically involves at an ASC like DOSC, from initial inquiry to first scheduled case.
Initial inquiry and facility review. Most surgeons start with a phone call or email to the Medical Staff Office to ask about case mix alignment, block availability, and whether the facility handles their specialty. This conversation is informal and takes about fifteen minutes. If there is a fit, credentialing paperwork is initiated.
Credentialing application. The application covers licensure, board certification, malpractice history, hospital privileges, and DEA registration. Most of the documents are the same ones used at any hospital credentialing. The Medical Staff Office will walk through exactly what is needed and follow up on any gaps so the packet moves cleanly through peer review.
Peer review and provisional privileges. Once the packet is complete, the Medical Director reviews it alongside the governing board. For straightforward applications, this step typically takes two to four weeks. Provisional privileges are granted for an initial period, during which the physician may begin scheduling cases.
First case scheduling. The Scheduling Office works with the surgeon’s team to identify available OR time. For surgeons without an established block, the initial cases are typically scheduled around available open time. Block time requests can be evaluated after a baseline case volume is established. The team is accustomed to coordinating with both solo practices and larger surgical groups.
- What to bring for the first case: implant and vendor preferences (coordinated by our team in advance), any specific instrument preferences or tray cards, and a direct contact at your practice for day-of logistics
- Anesthesia coordination: DOSC’s credentialed anesthesia providers handle pre-op assessment and anesthesia management; surgeons who prefer a specific anesthesiologist can request case-by-case coordination
- Post-case documentation: operative note routing can be configured to match your existing EMR workflow or handled on paper, per preference
Questions that come up before the first case are expected and welcome. The Medical Staff Office is the single point of contact through the credentialing period and can route facility, scheduling, or billing questions to the right department.

Physician FAQ
Do you accept lien and personal-injury cases?
Yes. DOSC works on medical liens for personal-injury and select workers’-compensation cases. The treating physician’s office coordinates lien intake with our billing team, and we can coordinate records and billing with the patient’s attorney. See For Attorneys for how referrals work.
Can I bring a single case, or do I need ongoing volume?
Both. Full credentialing is available for ongoing case volume, and single-case / temporary privileges are available where appropriate — so you can bring one case without a long-term commitment.
How does credentialing work, and how long does it take?
Complete our credentialing packet and email it to credentialing@downeyoutpatient.com. Most complete applications are reviewed by the Credentials Committee within 30–45 days of receiving all required documentation; provisional privileges may let you begin scheduling sooner.
How does scheduling and block time work?
Surgeons with consistent volume can request protected block time — half-day, full-day, or recurring weekly. Open and add-on time is available for one-off or urgent cases, and a dedicated scheduling coordinator handles your office’s bookings.
Do you coordinate with personal-injury attorneys?
Yes. For injury cases we coordinate scheduling, records, and lien billing with the referring physician’s office and the patient’s attorney. More detail is on our For Attorneys page.
