California · Federal IDR + state pathway
Out of network Repeat lumbar discectomy, single interspace in California, CPT 63042
California runs its own process alongside the federal one. Which applies depends on the plan.
An underpaid Repeat lumbar discectomy, single interspace (CPT 63042) claim in California does not have one dispute route — it has two, and picking the wrong one costs the claim. State-regulated DMHC and CDI plans follow California's IDRP. Self-funded ERISA plans follow the federal IDR process. Confirm routing by plan type before filing.

How California handles an out-of-network Repeat lumbar discectomy, single interspace payment
California runs a binding Independent Dispute Resolution Process (IDRP) for out-of-network payment disputes (AB 72, 2016; Health & Safety Code §1371.9 / Insurance Code §10112.8). Plans pay the greater of their average contracted rate or 125% of Medicare, and either side may take the claim to the DMHC or CDI IDRP for a higher or lower amount.
Payment is benchmarked to the greater of the plan's average contracted rate or 125% of Medicare, then adjustable through the binding IDRP.
Applies to non-emergency care by a non-contracting provider at an in-network facility; the patient owes only in-network cost-sharing.
Routing decides the deadline. State-regulated DMHC and CDI plans follow California's IDRP. Self-funded ERISA plans follow the federal IDR process. Confirm routing by plan type before filing. Two patients can receive the same Repeat lumbar discectomy, single interspace at the same facility and their claims follow different processes with different clocks. Confirm plan type against the CMS applicability chart before filing.
Why CPT 63042 gets paid short out of network
Anchored to the qualifying payment amount (QPA)
The plan pays Repeat lumbar discectomy, single interspace at its own qualifying payment amount — its median in-network rate for the area — and treats that as the answer. Under the No Surprises Act the QPA is the plan's opening anchor, not a cap, and certified IDR entities weigh several other factors against it.
Out-of-network reduction with no contract on file
With no negotiated rate for Repeat lumbar discectomy, single interspace (CPT 63042), the allowed amount is reduced to an out-of-network schedule that rarely reflects what the lumbar spine procedure actually involves in a hospital setting.
This is the national picture for the code. For the full breakdown see Repeat lumbar discectomy, single interspace (CPT 63042), and for every procedure disputed in this state see California out-of-network IDR.
