Medical Billing Services in California
Medical billing for California practices — Noridian Medicare, Medi-Cal and its managed care plans, and the delegated IPA and medical group model that makes California billing unlike any other state.
California Billing Has a Layer Other States Don’t
In much of California, the health plan is not the only payer you deal with. Many HMO patients are assigned to an independent physician association (IPA) or medical group that receives capitated payments and pays claims itself. Billing the health plan instead of the delegated group — or the wrong group — is one of the most common California denials.
On top of that, Medi-Cal is administered by the Department of Health Care Services (DHCS), most members are enrolled in Medi-Cal managed care plans, and Medicare Part B claims go to Noridian Healthcare Solutions. Commercial plans include Anthem Blue Cross, Blue Shield of California, Health Net, UnitedHealthcare, Aetna and Cigna.

Do you provide medical billing services throughout California?

Why are California HMO claims denied for the wrong payer?
Many California HMO members are assigned to an IPA or medical group that is financially responsible for their care. Claims must go to that delegated group, not the health plan. We check each patient’s assigned group during eligibility verification.
How do providers enroll in Medi-Cal?
Most providers enroll through DHCS’s Provider Application and Validation for Enrollment (PAVE) portal, then credential with the Medi-Cal managed care plans they want to see patients from.
