Physician billing · California
Physician billing services in California mean working the most complex payer market in the country — county-organized Medi-Cal managed care, dozens of commercial plans, DMHC prompt-pay rules, and a Part B contractor covering the whole West Coast.
247MBS has run that professional-fee revenue cycle for independent groups since 2005, giving practices in Los Angeles, San Diego, San Jose, San Francisco, and Sacramento a dedicated account manager, a free 360° reporting dashboard, and HIPAA plus SOC 2 Type II security built for California's scale.
There is no market where handing this off matters more: a specialized physician billing company absorbs the county-by-county Medi-Cal plan variation, multi-carrier paneling, prior-auth chasing, and E&M defense that would overwhelm an in-house biller trying to cover a busy California group alone. As an established medical billing services company, 247MBS brings AAPC- and AHIMA-credentialed coders, HBMA-aligned processes, and measurable results — a 99% first-pass clean-claim rate, up to 40% fewer denials, roughly 90% of worked denials recovered, and days in A/R held under 25. When you outsource to a professional team, more of what a California practice earns actually lands, and it keeps landing through staff turnover.
Outsourcing here buys more than claim submission. Our credentialing services close the enrollment gaps that keep physicians off Medi-Cal and commercial panels, front-end verification confirms which plan a patient carries in a county with several Medi-Cal options, and disciplined denial rework recovers dollars a busy office would otherwise write off — and DMHC prompt-pay rules give us leverage to press slow payers. A dedicated account manager owns your numbers, and the free dashboard shows every claim in real time — the difference between a transactional billing company and a partner accountable for collections. See the national physician billing hub and our California billing overview. With 98% client retention since 2005, most groups that switch stay.
California delivers Medi-Cal, its Medicaid program, largely through managed care, and the plan lineup changes by county: L.A. Care and Health Net in Los Angeles, IEHP in the Inland Empire, CalOptima in Orange County, Partnership HealthPlan across the north, plus Anthem, Molina, and Kaiser in various counties. A physician group in one county bills a completely different set of Medi-Cal plans than a group two counties over, and enrollment with each is required for claims to pay. The CalAIM initiative has added new care-coordination and billing pathways on top of that base. Medicare Part B claims run through Noridian Healthcare Solutions under Jurisdiction E, which covers California, Hawaii, and Nevada, and California's commercial market spans Anthem Blue Cross, Blue Shield of California, Kaiser, Health Net, and the national carriers — all governed by DMHC and Knox-Keene prompt-pay timelines that dictate when a clean claim must be paid.
UCLA Health, Cedars-Sinai, and Keck Medicine anchor Los Angeles; UC San Diego, Sharp, and Scripps anchor San Diego; Stanford and Santa Clara Valley serve the South Bay; UCSF and Sutter anchor San Francisco; and UC Davis anchors Sacramento — and among them thousands of independent single- and multi-specialty groups still run their own revenue cycle inside this payer maze.
Professional-fee revenue in California turns on accurate E&M level selection, defensible modifiers, and matching the site of service to the right rate. Our coders manage the building blocks below; codes stay inside the table.
| Service billed | Usual code set | What drives the payment |
|---|---|---|
| New patient office visit | 99202–99205 | 2021 MDM level or total time |
| Established patient visit | 99211–99215 | MDM or time; 99214/99215 down-code risk |
| Hospital inpatient/observation | 99221–99223 / 99231–99233 | 2023 merged observation into inpatient |
| E&M plus same-day procedure | Modifier 25 | Separately identifiable service |
| Professional vs technical read | Modifier 26 / TC | Split of a diagnostic service |
| Office vs facility site | POS 11 vs 19/22 | Non-facility vs facility rate |
| Medicare wellness visit | G0438 / G0439 | Annual eligibility window |
Each code and modifier earns payment only when the record supports the level, the modifier, and the place of service — the documentation Noridian and California's plans demand when they question a claim.
The preventable losses here come from the sheer number of plans and the paneling those plans require. The table shows what we stop before it reaches a payer.

Revenue review
A certified physician billing specialist reviews your coding, unit counts, authorizations and aged A/R against the payers you actually bill in California — and puts a number on what your current process is leaving on the table.

We handle billing for solo independent physicians, single- and multi-specialty groups, independent practice associations, physician-owned procedural practices, hospital-affiliated and faculty-plan physicians, office-based ambulatory physicians, telehealth physician groups, and locum or coverage physicians across Los Angeles, San Diego, San Jose, San Francisco, Sacramento, and the surrounding metros from the Inland Empire to the Bay Area. New physicians joining a California group get their credentialing, CAQH, and PECOS enrollment tracked from the offer letter forward; groups billing across office and hospital sites get consistent POS handling; and procedural practices get global-period tracking that separates bundled post-op care from genuinely billable visits. The aim never changes: every eligible encounter captured, coded to the level the record supports, and paid at the correct California rate.
Dependable medical billing for Physician practices in California means turning the country's most fragmented payer market into predictable cash flow. 247MBS runs the full professional-fee cycle for independent groups statewide — verifying which county Medi-Cal plan a patient actually carries, capturing evaluation-and-management levels the record supports, and submitting Medicare Part B claims through Noridian's Jurisdiction E. We manage multi-specialty coding, modifier discipline, and incident-to rules across busy schedules, then hold days in A/R under 25 with a 99% first-pass clean-claim rate. Commercial volume from Anthem Blue Cross, Blue Shield of California, and Kaiser is billed to each plan's own rules, not a generic template. Request a revenue review to see what your current process leaves on the table.
When you outsource Physician billing in California, the goal is simple: more of what your group earns reaches the bank, and it keeps arriving through staff turnover and seasonal volume swings. 247MBS takes on eligibility verification across the state's overlapping Medi-Cal plans, credentialing with CAQH and PECOS enrollment tracked to each panel's effective date, and denial rework backed by prompt-pay follow-up under California's own rules. Groups in Los Angeles, San Diego, the Bay Area, and Sacramento gain a coding team fluent in multi-specialty professional fees without carrying the cost of in-house hiring. With 98% client retention since 2005 and HIPAA plus SOC 2 Type II security, most practices that switch stay. Start with a no-cost review of your collections.

Yes. Because Medi-Cal plans vary by county, we verify each patient's specific plan before submission and keep your enrollment current with every plan you contract with, so claims adjudicate the first time instead of denying for a wrong-plan or paneling problem.
Yes. When a clean claim sits past the DMHC and Knox-Keene payment window, we follow up under those prompt-pay timelines and pursue interest where it applies, so slow payers do not quietly stretch your A/R.
Yes. We manage NPI, CAQH, PECOS, and reassignment of benefits and track each panel to its effective date, so a physician joining a California practice bills in-network from the first date of service.
Whether you are a solo practice or a multi-site group, we bill Physician across California under one dedicated account manager and a live dashboard — and treat every counted unit, authorization and appeal as recoverable revenue until it is safely paid.
