The start of a new year is the perfect time to reset habits, refine processes, and strengthen the foundation of accurate anesthesia coding. When it comes to clean claims and compliant billing, one truth remains constant:
CPT accuracy starts with ICD-10-CM.
While anesthesia coding often focuses heavily on time, units, and modifiers, none of that matters if the underlying diagnosis does not clearly support the service provided.
Every anesthesia claim tells a story—and ICD-10-CM codes set the stage. They explain why anesthesia was medically necessary and how complex the patient’s condition truly was.
Strong diagnosis documentation supports:
Without clear, specific diagnoses, even perfectly calculated anesthesia time can be challenged.
Many anesthesia documentation issues are not coding errors—they’re documentation gaps. Some of the most common include:
These gaps make it difficult to assign accurate ICD-10-CM codes, which can ultimately affect CPT code support and reimbursement.
Accurate anesthesia coding requires alignment across the entire record:
When these elements tell the same story, claims are stronger and audits are easier to defend.
ICD-10-CM specificity isn’t just a surgical concern—it directly impacts anesthesia services. Detailed diagnoses help reflect:
For example, documenting controlled vs. uncontrolled conditions, acute vs. chronic status, or complications can make a meaningful difference in how the case is reviewed.
As we move into the new year, consider these best practices:
Small improvements in documentation can have a big impact on CPT accuracy.
As we begin 2026, take a moment to reflect:
👉 If you could improve one anesthesia documentation issue this year, what would it be?
Drop a comment, reply to this post, or share your experience. Your insight may help another coder, auditor, or provider strengthen their documentation practices.
Here’s to a year of clean claims, strong documentation, and continued growth in anesthesia coding.

The first week of a new year always feels a little different, doesn’t it?
A fresh calendar. New goals. New possibilities.
As anesthesia coders, auditors, and educators, our field is constantly evolving—and staying current takes intention. So I want to hear from you:
👉 How do you plan to make 2026 your best year yet?
Are you:
There’s no “right” answer here—growth looks different for everyone. Some years are about pushing forward. Others are about refining what you already know. Both matter.
Drop a comment, reply to this post, or send a message and share what’s on the horizon for you in 2026. Your goals may inspire someone else who’s standing at the same starting line.
Here’s to a year of learning, growth, and supporting one another along the way.
Let’s make 2026 a strong one—together. 💙
2025 was a year of deep reflection for me.
It was the year I finally slowed down enough to ask myself some very hard questions:
Some of the answers I uncovered weren’t what I expected. And honestly, it took nearly the entire year before I fully realized what was missing.
What I learned is this: I hadn’t been thinking about me.
Once that realization set in, things began to shift. I started making intentional changes. I clearly defined what I wanted to accomplish for myself—not what was expected of me, not what felt “safe,” but what actually brought me purpose and joy.
Despite all of its ups and downs, 2025 ended on a really good note.
I launched my blog and began welcoming subscribers. I earned an additional certification. I enrolled in the AAPC Instructor Course. Most importantly, I gained clarity—clarity about my goals, my direction, and my why.
With a renewed vision, I’m stepping into 2026 with new expectations and new opportunities. I know that pursuing dreams doesn’t happen overnight. There will be setbacks, and that’s okay. It’s not a race. Growth happens one step at a time, as long as we keep moving forward and continue doing the things that bring us fulfillment.
That brings me to something I want to share with you.

Let’s make 2026 the best year yet—for our careers, our growth, and for chasing the dreams we’ve been putting off for far too long.
Here’s to learning, evolving, and believing in ourselves.
As we move closer to 2026, it’s time to start looking ahead at the upcoming CPT® code changes and what they mean for providers, coders, and revenue cycle teams. Each annual update reflects how healthcare continues to evolve—and the 2026 CPT code set is no exception.
Whether you’re involved in coding, billing, compliance, or clinical documentation, understanding the overall direction of these changes can help you prepare early and avoid last-minute surprises.
The 2026 CPT® code set includes a combination of new, revised, and deleted codes across multiple specialties. As with prior years, the intent is to improve accuracy, reflect current clinical practice, and better align reporting with how care is actually delivered.
Rather than focusing on volume alone, the 2026 updates emphasize:
Digital health continues to grow, and CPT® codes are evolving to keep pace. Updates for 2026 further refine reporting for remote patient monitoring (RPM) and related management services, including clearer guidance around monitoring duration and time-based thresholds.
These changes aim to:
The 2026 CPT® updates acknowledge the expanding role of advanced technology and algorithm-assisted analysis in clinical care. New and revised codes capture services where clinicians use advanced tools to support interpretation, decision-making, and diagnostic insight.
This is an important step toward recognizing how technology enhances—but does not replace—clinical judgment.
Several procedural areas see refinement in 2026, particularly where prior coding structures lacked clarity or failed to reflect procedural complexity.
Expect updates that:
These refinements are especially important for accurate documentation and audit defense.
Across the code set, there is a noticeable focus on clearer definitions and parenthetical guidance. This includes refined descriptors, updated instructional notes, and clearer expectations for reporting.
For coders and auditors, this means:
With an effective date of January 1, 2026, preparation is key. Now is the time to:
Early education and proactive planning can significantly reduce claim delays, denials, and rework once the new code set goes live.
The 2026 CPT® code changes reflect a broader shift in healthcare—one that values precision, technology integration, and documentation that tells the full story of patient care.
In upcoming posts, we’ll take a deeper dive into specialty-specific updates, highlight high-impact changes, and share practical tips for applying the new codes confidently.
If there’s a specific area you’d like covered in addition to anesthesia – such as cardiovascular services, or another specialty—I’d love to hear your suggestion. Remember in order to ensure that we have the correct crosswalk, it al begins with the CPT code.

I wanted to check in with the community—is anyone currently preparing for the CANPC (Certified Anesthesia and Pain Management Coder) exam? If so, I’d love to hear from you!
Studying for CANPC can feel overwhelming at times. Between mastering anesthesia time, navigating ASA crosswalks, understanding pain management interventions, and keeping up with evolving guidelines, there’s a lot to juggle. But we don’t have to do it alone.
What are you finding most challenging?
– Anesthesia coding concepts?
– Interventional pain procedures?
– Nerve blocks and imaging guidance?
– Modifiers?
– Time calculations?
– Exam strategy?
Drop a comment below and share what you’re struggling with — or even a tip that has helped you. Together, we can create a supportive space for everyone on their CANPC journey.
Let’s learn from each other and encourage one another to keep going.
• Assigned by ASA to each anesthesia CPT code.
• Represent procedure complexity.
• Fixed amount—does not change with case duration.
• Begins when anesthesia care starts; ends when no longer personally providing services.
• Most payers: 1 unit = 15 minutes.
• Medicare: billed based on actual minutes.
How to calculate and report anesthesia time properly depends on the payer. For payers that follow CPT® rules, report time per 15 minute intervals. At least half this time (7.5 minutes) must pass to report a unit. For example:
30 minutes of anesthesia = two units (30=15+15)
38 minutes of anesthesia = three units (38=15+15+8)
37 minutes of anesthesia = two units (37=15+15+7)
Medicare providers follow Centers for Medicare & Medicaid Services guidelines, found in the Internet Only Manual, Claims Processing
Manual 100-04 Chapter 12:
G. Anesthesia Time … is defined as the period during which an anesthesia practitioner is present with the patient. It starts when the anesthesia practitioner begins to prepare the patient for anesthesia services in the operating room or an equivalent area and ends when the anesthesia practitioner is no longer furnishing anesthesia services to the patient, that is, when the patient may be placed safely under postoperative care. Anesthesia time is a continuous time period from the start of anesthesia to the end of an anesthesia service. In counting anesthesia time for services furnished on or after January 1, 2000, the anesthesia practitioner can add blocks of time around an interruption in anesthesia time as long as the anesthesia practitioner is furnishing continuous anesthesia care within the time periods around the interruption. Actual anesthesia time in minutes is reported on the claim. For anesthesia services furnished on or after January 1, 1994, the A/B MAC computes time units by dividing reported anesthesia time by 15 minutes. Round the time unit to one decimal place. The A/B MAC does not recognize time units for CPT codes 01995 or 01996. For purposes of this section, anesthesia practitioner means a physician who performs the anesthesia service alone, a CRNA who is not medically directed, or a CRNA or AA, who is medically directed. The physician who medically directs the CRNA or AA would ordinarily report the same time as the CRNA or AA reports for the CRNA service.
• Added based on patient risk or circumstances.
• Physical Status: P3 (+1), P4 (+2), P5 (+3) for commercial payers.
• Emergency modifier (ET) may increase payment.
• Medical direction modifiers (AA, QK, QX, QZ) affect payment split.
• (Base Units + Time Units + Modifying Units) × Conversion Factor (CF) = Charge
Procedure: Lap Chole (ASA 00790)
Base Units: 7
Time: 90 minutes → 6 units (90 ÷ 15)
Modifier: P3 (+1 unit)
CF: $25
Total Units: 7 + 6 + 1 = 14
Charge: 14 × $25 = $350
• Accurate anesthesia start & stop times required.
• Only one ASA code billed per encounter.
• Include provider type (MD/CRNA) and applicable modifiers.
Charges depend on:
• Base Units
• Time Units
• Modifying Units
• Conversion Factor
Formula: Total Units × CF = Reimbursement
