Preferred Healthcare Management in Chula Vista has provided medical-billing and practice-management services from an Anchorage Place office in the 91914 Rolling Hills corridor since the firm's founding in 2007. The company's billing platform processes claims for cardiology practices including Dr. Sonia Ponce at Community Cardiology Clinic, handling CPT-coded charge entry, EOB posting, and payer-specific appeal workflows. HIPAA-compliant service lines encompass electronic and paper claim submission, accounts-receivable follow-up, denial management, physician credentialing with commercial and government payers, and insurance fee-schedule maintenance across all medical specialties from oncology to OB-GYN. Primary-care providers coordinating referral-driven billing cycles work alongside practitioners such as Martha E. Lozano, MD, Inc. within the same South Bay provider network that PHM's credentialing division enrolls and re-validates. Full-cycle revenue engagements convert charge-capture data into EDI 837P electronic claims within 24 to 48 hours of receipt, run ERA 835 auto-posting against practice-management system ledgers, and generate monthly A/R aging reports segmented by payer class, timely-filing threshold, and denial-reason code.
