A hands-on coding practice lab. See how one word, one side of the body, or one character can change the code, then prove it on three interactive cases.
2 short lessons + 3 interactive casesAbout 20 minutesBeginner friendlyPresented by Beth Schleeper
Anatomy of a specific code
Every character in a code has a job
This is the code you will build yourself in Case 2. Each box is earned from the documentation.

By the end you will be able to
Spot the single detail that changes a code choice
Use the four-part specificity check: diagnosis, location, laterality, encounter
Build a code character by character from the documentation
Know when to code as documented and when to ask the provider
Before you start
This is a simplified educational exercise. It is not a substitute for the complete record, the current code set, official guidelines, payer rules, or instructor review.
Good coders are not fast readers. They are careful readers. Today you will train your eye to catch the small details that make a code accurate.
Lesson 1
Why one word matters
Two notes can look almost identical and still need different codes.
ICD-10-CM is built for detail. Many codes change based on a confirmed diagnosis, the body site, the side of the body, and the type of encounter. If you skim, you miss the word that matters.
Spot the difference
Find the one detail that changes the code
Read both notes. Tap the word in Note B that would change the code.

The habit to build
Before you open any code book, slow down and ask: what is the diagnosis, where is it, which side, and what kind of visit is this? Those four answers do most of the work.
Lesson 2
The specificity check
Four questions to ask before you look up any code.
D
Diagnosis
What did the provider confirm? A symptom or an established condition?
bursitis
L
Location
Which body site or structure is involved?
shoulder
L
Laterality
Right, left, or bilateral, if the code set asks for it.
left
E
Encounter
For injuries: initial, subsequent, or sequela.
initial encounter
Try it
Sort the details
Tap a detail, then tap the box it belongs in. Place all twelve, then check your work.
Diagnosis
Location
Laterality
Encounter
The golden ruleSpecificity comes from the documentation, never from assumption. If the detail is not in the record, you do not add it. You will practice exactly that in Case 3.
Interactive case 1 of 3
The left shoulder
Case 1Office visit · Established patient · 52-year-old
Symptom or diagnosis? Read the whole note before you decide.
Office visit · Progress noteEstablished patientTraining example
Chief complaintPain in the leftshoulder for three weeks, worse reaching overhead. No injury.
Exam
Tenderness over the lateral left shoulder. Full range of motion with pain at end range.
AssessmentBursitis of the leftshoulder.
Plan
Ice, anti-inflammatory medication, home exercises. Return in four weeks.
Step 1 · Tag it
Tag the specificity details
Choose a label, then tap each underlined word. Every underlined word gets one label.
Step 2 · Choose it
Pick the code from the Tabular List
Simplified training excerpt based on ICD-10-CM. Choose the code that matches the provider's final assessment.
BS
Why this matters
The chief complaint tells you why the patient came in. The assessment tells you what the provider concluded. When a definitive diagnosis is documented, the symptom that comes with it is not coded separately.
Interactive case 2 of 3
The ankle sprain
Case 2Urgent care · New problem · 24-year-old
Build the code one character at a time. Each character must be earned from the note.
Urgent care · Visit 1Training example
Code builder
The index entry Sprain, ankle points to subcategory S93.40-, sprain of unspecified ligament of ankle. Two characters are still missing.
BS
About the 7th character
Injury codes need a 7th character. A is used while the patient is receiving active treatment. D is used for routine care during healing or recovery. S is for a later complication or condition that results from the injury. Same sprain, different character.
Interactive case 3 of 3
The chart audit
Case 3Three charts · Your call on each one
Code as documented, or ask the provider? Never guess.
You are reviewing three charts before they are billed. For each one, decide what a careful coder should do. Read every section. The detail that matters may be hiding in the procedure line.
Chart 1 · PediatricsOpen
AssessmentAcute otitis media, left ear.PlanAntibiotic for 10 days. Recheck in two weeks if not improved.
Chart 2 · OrthopedicsOpen
AssessmentPrimary osteoarthritis, right knee.ProcedureCorticosteroid injection, left knee. Patient tolerated well.
Chart 3 · Family medicineOpen
ExamTenderness over the shoulder. No side recorded anywhere in the note.AssessmentBursitis, shoulder.

A query is a professional skill
A query is a respectful, non-leading question to the provider asking them to clarify the record. It is how coders protect accuracy without putting words in the provider's mouth. We practice writing compliant queries in the CPC® course.

Where this leads
From specificity to CPC® certification
The precision you practiced today is built into the ACS 20-week CPC® Online Course.
The Certified Professional Coder (CPC®) credential shows your expertise in code selection and in following medical coding guidelines. The ACS course takes you from documentation and ICD-10-CM basics to coding operative reports and evaluation and management services, with a final exam and review before the certification exam.
The 20-week roadmap
Week 1
Medical coding and complianceAccuracy, ethics, and why compliance matters. Including when to query.
Week 2
Anatomy, terminology, documentation and guidelinesBody sites and laterality, the "L" and "L" in your specificity check.
Weeks 3–4
ICD-10-CM Parts I and IIIndex, tabular list, conventions, 7th characters, and Official Coding Guidelines. You practiced this today
Week 5
Introduction to CPT® and HCPCSCoding the procedures and services, not just the diagnoses.
Weeks 6–7
Evaluation and ManagementPrinciples, then real application and E/M auditing.
Week 8
ModifiersProper use of AMA coding modifiers, including laterality modifiers for procedures.
Weeks 9–19
Body systems, anesthesia, radiology, pathology, and medicineFrom integumentary and musculoskeletal through cardiovascular, digestive, nervous system, and more.
Week 20
Final exam and reviewAn overall review before the Certification Exam.
