Billing & Coding Resource Center

A working reference for the codes that actually cause confusion in behavioral health, urgent care, and pain management billing, built from claims we’ve reviewed, not copied from a generic code list.

Filters the list below as you type. Works for code numbers or plain terms like “epidural”.

No codes match that search. Try a code number like “90837” or a term like “injection”.
Why practices outsource

The patterns we see most often

Every practice that looks into outsourcing is dealing with some version of the same handful of problems. Here’s what actually drives that decision, honestly, not a sales pitch.

Billing staff turnover

Experienced coders and billers are hard to hire and harder to keep, especially for independent practices competing against hospital systems on salary. Every time someone leaves, institutional knowledge about your specific payer quirks leaves with them.

Denial rates that keep climbing

Initial claim denial rates are sitting around 11.65% nationally and trending up year over year, according to HFMA’s own benchmarking data. That’s not a one-off problem, it’s a structural one that keeps compounding without dedicated attention.

Payer rules that vary by contract

As the codes on this page show, the same claim can be coded correctly and still get denied because a specific payer handles it differently. Keeping track of that across every payer you’re contracted with is a full-time job on its own.

Time pulled away from patients

Every hour a clinician or office manager spends chasing a denied claim is an hour not spent on care or growing the practice. For a lot of independent practices, that tradeoff is what finally tips the decision.

Recognize your practice in any of this?

We work specifically with behavioral health, urgent care, and pain management practices. A free audit shows you exactly where your own claims are getting stuck, using your actual data, not a generic checklist.
