Medical Billing. Simplified

Integrated credentialing + billing, sub‑week onboarding, and root‑cause denial prevention for outpatient mental health and select specialties.

Why Choose OneSource RCM?

Fast Go‑Live (Under a Week)

Signed and stuck waiting? We run credentialing and billing setup together so active practices submit clean claims inside the first week.

Stop Repeat Denials

Tired of the same payer reasons? Each denial becomes a prevention rule (modifier/POS, auth, eligibility) so recurrence drops and first pass climbs.

System That Works For You

Vendors that just “submit” keep you in rework. We reconfigure templates, POS/modifiers, taxonomy, and auth fields to eliminate avoidable edits before they happen.

Clarity You Can Act On

Clear first pass %, denial shifts, recovery %, AR aging movement. No noise dashboards. You always know what to do next.

Clean Claim Flow (Medical Billing & RCM)

Still fixing the same edits? We rebuild charge templates, POS/modifier defaults, taxonomy mapping, and auth capture so more claims pay first pass. Target: ≥90% first pass by Day 60.

Integrated Credentialing (Every Engagement)

Panel gaps and missing EFT/ERA forms delay cash. We manage enrollments, CAQH, revalidations, taxonomy, and payer rules inside billing so new claims drop cleanly. Goal: No revenue dip at go live.

Practice Optimization & Automation

Manual eligibility checks, auth confusion, and duplicate entry waste minutes per encounter. We embed eligibility prechecks, auth matrix, modifier rules, and targeted automation. Result: Fewer repeat denials and reclaimed staff time.

Who We Help...

Tailored solutions for practices of every shape and specialty.

Work directly with us—whether we’re upgrading forms after hours or walking you through a denial.

Solo / Emerging PMHNP
Wear every hat and losing time to auths + panel chases? We run credentialing and billing build together (CAQH, taxonomy, EFT/ERA, POS/modifier map) so you submit clean claims inside week one.

Outcome: no revenue dip; more patient hours.

Growing Psychiatry Group
Adding prescribers exposes repeat taxonomy + modifier denials and auth chaos. We centralize an auth matrix, tag every denial to root cause, and convert patterns into rules.

Outcome: denial recurrence drops; provider ramp speeds up.

Therapy Group Adding Med Management
New prescriber? Credentialing lag and telehealth modifier confusion stall payment. We align taxonomy, map CPT/POS/modifiers, track panels inside billing.

Outcome: medication visits paid correctly from the start.

Selective Specialty (Derm / Primary / Integrative)
Prior vendor just “submitted” charges; aging bloated; underpayments slipped by. We rebuild templates, install fee schedule variance checks, and root cause denial tagging.

Outcome: faster cash, shrinking aging, captured underpayments.

New Practice Startup

Launching and still pulling pieces together (enrollments, EIN/Group NPI, CAQH, fee schedules, EFT/ERA)? We sequence credentialing, system configuration, and first claim tests in parallel so you are not burning early weeks on preventable admin lag.

Outcome: Faster first payer approvals and earlier clean cash.

Telehealth / Hybrid Model

Multiple POS codes, mixed state telehealth rules, and modifier confusion causing edits or underpayments. We map payer specific telehealth requirements (modifiers, POS, taxonomy nuances) and embed them in templates so remote and in person claims pay correctly.

Outcome: Clean telehealth reimbursement without manual overrides.

Physical Therapy Practice

High visit volume plus plan of care, authorization, and modifier (GP/59/KX) pitfalls driving repeat denials and recoup risk. We centralize auth and recert tracking, configure required modifiers, and monitor utilization thresholds.

Outcome: Fewer repeat auth/modifier denials and steadier weekly cash.

Family Medicine / Primary Care

Broad payer mix, chronic care codes underutilized, and lingering small balance AR from passive clean up. We tune preventative vs problem visit coding rules, eligibility prechecks, and variance monitoring to catch underpayments early.

Outcome: Improved capture of covered services and cleaner aging buckets.
