Every textbook chapter has a workbook chapter to match it.
The CALHLTH Pro Medical Billing and Coding Student Workbook moves from vocabulary to application through six structured sections: Key Terms Matching, Fill-in-the-Blank, Multiple Choice, Coding Exercises, Short Answer, and Case Study. Forty-eight chapters covering the complete revenue cycle, ICD-10-CM, CPT, HCPCS Level II, HIPAA, compliance, denial management, and California-specific billing rules.
Designed for students who want to do the work, not just read about it.
Companion to CALHLTH Pro Medical Billing and Coding — A Course Textbook (A.J. Moreno). calhlthpro.com
You can learn medical billing from a textbook that treats California as a footnote. Or you can learn it from one built for the state where you'll actually work.
CALHLTH Pro Medical Billing and Coding — A Course Textbook covers everything a billing and coding professional needs to know: the 10-step revenue cycle, real-time eligibility verification, prior authorization, ICD-10-CM diagnosis coding across all body systems, CPT procedure coding from E/M through surgery through specialty systems, HCPCS Level II, HIPAA, fraud and abuse compliance, denial management, and accounts receivable. All of it current to the 2026 code year.
What this textbook adds that others don't: forty-eight chapters built around the California payer landscape. Medi-Cal FFS and managed care billing. CalAIM Enhanced Care Management. AB 72 balance billing law. The Knox-Keene Act and DMHC enforcement. California CMIA privacy standards. Workers' Compensation OMFS. These topics appear in the units where coders actually use them — not in a single California chapter at the back.
Every chapter follows the same structure: learning objectives, numbered content sections, California-specific callouts, a clinical scenario, and a chapter summary. Designed for use with the companion Student Workbook and the CALHLTH Pro LMS.

A.J. Moreno maps the fault lines between longing and ruin, delivering speculative fiction that is intellectually precise and morally unforgiving.
A.J. Moreno crafts fiction that moves like a current beneath the skin — deliberate, intelligent, and restless. Blending the speculative scale of science fiction with the intimate brutality of horror and the charged intimacy of erotic storytelling, his work interrogates the moral costs of ambition, the architecture of longing, and what it means to confront the unknown. Raised in California’s North Bay, Moreno brings a meticulous approach to research and a novelist’s ear for the unsettling detail. His prose is unsparing yet elegiac: characters are drawn with clarity, scenarios are built with technical exactness, and the emotional stakes are never theatrical. A collaborator and provocateur, he seeks out writers and projects that expand the limits of genre while demanding the reader’s full attention. If his stories do one thing consistently, it is this: they force you to see what you ignored yesterday and to reckon with what you’ll fear tomorrow.
Quick Reference Companion
The definitive desk reference for medical billers, coders, patient registrars, and healthcare office professionals navigating California's complex insurance and billing landscape — fully updated for 2025–2026.
The Elir predates every empire in the known galaxy. Born from conditions identical to the ones that produced the universe itself, it fuses permanently to neural matter at birth. No surgery separates host from particle. No technology stabilizes extraction. Every attempt on record has killed the host from inside out.
The Katar exist for one reason: ensure no single host accumulates five particles. Five is the documented threshold for a Pentamear convergence. The last one left a cosmological catastrophe still drifting through deep space. The Katar have kept that threshold theoretical for centuries by eliminating Elirian hosts before the count climbs.
Earth scientists called the particle TRACE 8489. It was the 8,489th simulation in which it persisted past three seconds. They logged it as an anomaly.
It wasn't an anomaly.
It was a host selecting itself.
The Katar have read the data. They know what the particle chose. They have one operational mandate.
Earth has never been on their route before.
