Specifying anatomical location and laterality required by ICD-10 is easier than you think. This detail reflects how
physicians and clinicians communicate and to what they pay attention - it is a matter of ensuring the information is
captured in your documentation.
In ICD-10-CM, there are three main categories of changes:
Denition Changes
Terminology Dierences
Increased Specicity
Over 1/3 of the expansion of ICD-10 codes is due to the addition of laterality (left, right, bilateral). Physicians and other
clinicians likely already note the side when evaluating the clinically pertinent anatomical site(s).
HYPERTENSION
Denition Change
In ICD-10, hypertension is defined as essential (primary). The concept of “benign or malignant” as it relates to
hypertension no longer exists.
When documenting hypertension, include the following:
1. Type e.g. essential, secondary, etc.
2. Causal relationship e.g. Renal, pulmonary, etc.
Primer for Family Practice Clinical
Documentation Changes
ICD-10 Compliance Date: October 1, 2015
I10 Essential (primary) hypertension
I11.9 Hypertensive heart disease without heart failure
I15.0 Renovascular hypertension
ICD-10 Code Examples
10
ASTHMA
Terminology Dierence
ICD-10 terminology used to describe asthma has been updated to reflect the current clinical classification system.
When documenting asthma, include the following:
1. Cause Exercise induced, cough variant, related to smoking, chemical or
particulate cause, occupational
2. Severity Choose one of the three options below for persistent asthma patients
1. Mild persistent
2. Moderate persistent
3. Severe persistent
3. Temporal Factors Acute, chronic, intermittent, persistent, status asthmaticus,
acute exacerbation
UNDERDOSING
Terminology Dierence
Underdosing is an important new concept and term in ICD-10. It allows you to identify when a patient is taking less
of a medication than is prescribed.
When documenting underdosing, include the following:
1. Intentional, Unintentional,Non-compliance Is the underdosing deliberate? (e.g., patient refusal)
2. Reason Why is the patient not taking the medication?
(e.g.financial hardship, age-related debility)
J45.30 Mild persistent asthma, uncomplicated
J45.991 Cough variant asthma
Z91.120 Patient’s intentional underdosing of medication regimen due to
financial hardship
T36.4x6A Underdosing of tetracyclines, initial encounter
T45.526D Underdosing of antithrombotic drugs, subsequent encounter
ICD-10 Code Examples
ICD-10 Code Examples
11
ABDOMINAL PAIN AND TENDERNESS
Increased Specicity
When documenting abdominal pain, include the following:
1. Location e.g. Generalized, Right upper quadrant, periumbilical, etc.
2. Pain or tenderness type e.g. Colic, tenderness, rebound
DIABETES MELLITUS, HYPOGLYCEMIA AND HYPERGLYCEMIA
Increased Specicity
The diabetes mellitus codes are combination codes that include the type of diabetes mellitus, the body system
affected, and the complications affecting that body system.
When documenting diabetes, include the following:
1. Type e.g. Type 1 or Type 2 disease, drug or chemical induced, due to underlying
condition, gestational
2. Complications What (if any) other body systems are affected by the diabetes condition? e.g. Foot
ulcer related to diabetes mellitus
3. Treatment Is the patient on insulin?
A second important change is the concept of “hypoglycemia” and “hyperglycemia.” It is now possible to document
and code for these conditions without using “diabetes mellitus.” You can also specify if the condition is due to a
procedure or other cause.
The final important change is that the concept of “secondary diabetes mellitus” is no longer used; instead, there are
specific secondary options.
R10.31 Right lower quadrant pain
R10.32 Left lower quadrant pain
R10.33 Periumbilical pain
E08.65 Diabetes mellitus due to underlying condition with hyperglycemia
E09.01 Drug or chemical induced diabetes mellitus with
hyperosmolarity with coma
R73.9 Transient post-procedural hyperglycemia
R79.9 Hyperglycemia, unspecified
ICD-10 Code Examples
ICD-10 Code Examples
12
INJURIES
Increased Specicity
ICD-9 used separate “E codes” to record external causes of injury. ICD-10 better incorporates these codes and
expands sections on poisonings and toxins.
When documenting injuries, include the following:
1. Episode of Care e.g. Initial, subsequent, sequelae
2. Injury site Be as specific as possible
3. Etiology How was the injury sustained (e.g. sports, motor vehicle crash, pedestrian,
slip and fall, environmental exposure, etc.)?
4. Place of Occurrence e.g. School, work, etc.
Initial encounters may also require, where appropriate:
1. Intent e.g. Unintentional or accidental, self-harm, etc.
2. Status e.g. Civilian, military, etc.
Example 1:
A left knee strain injury that occurred on a private recreational playground when a child landed
incorrectly from a trampoline:
Injury: S86.812A, Strain of other muscle(s) and tendon(s) at lower leg level,
left leg, initial encounter
External cause: W09.8xxA, Fall on or from other playground equipment,
initial encounter
Place of occurrence: Y92.838, Other recreation area as the place of occurrence
of the external cause
Activity: Y93.44, Activities involving rhythmic movement, trampoline jumping
Example 2:
On October 31st, Kelly was seen in the ER for shoulder pain and X-rays indicated there was
a fracture of the right clavicle, shaft. She returned three months later with complaints of
continuing pain. X-rays indicated a nonunion. The second encounter for the right clavicle
fracture is coded as S42.021K, Displaced fracture of the shaft of right clavicle, subsequent for
fracture with nonunion.

Quality clinical documentation is essential for communicating the intent of an encounter, confirming medical necessity,
and providing detail to support ICD-10 code selection. In support of this objective, we have provided outpatient focused
scenarios to illustrate specific ICD-10 documentation and coding nuances related to your specialty.
The following scenarios were natively coded in ICD-10-CM and ICD-9-CM. As patient history and circumstances will
vary, these brief scenarios are illustrative in nature and should not be strictly interpreted or used as documentation and
coding guidelines. Each scenario is selectively coded to highlight specific topics; therefore, only a subset of the relevant
codes are presented.
Family Practice Clinical Scenarios
ICD-10 Compliance Date: October 1, 2015
Scenario Details
Chief Complaint
• “My stomach hurts and I feel full of gas.”
History
• 47 year old male with mid-abdominal epigastric pain
1
, associated with severe nausea &
vomiting; unable to keep down any food or liquid. Pain has become “severe” and constant.
• Has had an estimated 13 pound weight loss over the past month.
• Patient reports eating 12 sausages at the Sunday church breakfast five days ago which he
believes initiated his symptoms.
• Patient admits to a history of alcohol dependence
2
. Consuming 5 – 6 beers per day now, down
from 10 – 12 per day 6 months ago. States that he has nausea and sweating with “the shakes”
when he does not drink.
Exam
• VS: T 99.8°F, otherwise normal.
• Mild jaundice noted.
• Abdomen distended and tender across upper abdomen
3
. Guarding is present. Bowel sounds
diminished in all four quadrants.
• Oral mucosa dry, chapped lips, decreased skin turgor
Scenario 1: Abdominal Pain
14
Assessment and Plan
• Dehydration and suspected acute pancreatitis.
• Admit to the hospital. Orders written and sent to on-call hospitalist.
• 1L IV NS started in office. Blood drawn for labs.
• Recommend behavioral health counseling for substance abuse assessment and
possible treatment.
• Patient’s wife notified of plan; she will transport to hospital by private vehicle.
Summary of ICD-10-CM Impacts
Clinical Documentation
1. Describe the pain as specifically as possible based on location.
2. When addressing alcohol related disorders you should distinguish alcohol use, alcohol abuse,
and alcohol dependence. ICD-10-CM has changed the terminology and the parameters for
coding substance abuse disorders. In this encounter note, as the acute pancreatitis is
suspected, and the patient’s alcohol intake status is stated, the associated alcoholism
code is listed.
3. Abdominal tenderness may be coded. Ideally the documentation should include right or left
upper quadrant and indicate if there is rebound in order to identify a more specific code.
Currently the ICD-10 code would be R10.819, Abdominal tenderness, unspecified site as the
documentation is insufficient in laterality and specificity.

• Vitals: BP is 159/95, otherwise normal. Per patient, he had good control of BP on meds,
but it has risen without medication.
• BUN/creatinine normal limits.
Assessment and Plan
• HTN noted on exam today. Change from olmesartan medoxomil to metoprolol tartrate 50 mg
once daily, will titrate dosage every two weeks until BP normalizes.
• Discussed the importance of daily home BP monitoring, low sodium diet, and taking BP
medication as prescribed; he verbalizes understanding.
• Schedule follow-up visit in two weeks to evaluate effectiveness of new BP medication therapy,
and repeat BUN/creatinine.
Scenario 2: Annual Physical Exam
16
Summary of ICD-10-CM Impacts
Clinical Documentation
1. Documenting why the encounter is taking place is important, as the coder may assign a
different code based on the type of visit (e.g., screening, with no complaint or suspected
diagnosis, for administrative purposes). In this situation, the patient is requesting an encounter
without a complaint, suspected or reported diagnosis.
2. Document that the patient is noncompliant with his medication. This “underdosing” concept
can often be coded, along with the patient’s reason for not taking the prescribed medications.
Document if there is a medical condition linked to the underdosing that is relevant to the
encounter, and ensure the connection is clearly made. The ICD-10-CM terms provide new
detail as compared to the ICD-9-CM code V15.81, history of past noncompliance. In this case
there was no noted history of noncompliance. In this note the side effects of stopping the
medication include headache, which remains as a patient complaint for this encounter. When
documenting headache do differentiate if intractable versus non-intractable.
Coding
Other Impacts
• Assess if the new patient-centric preventative health incentives for annual exams are relevant
to your practice.
• For hierarchical condition categories (HCC) used in Medicare Advantage Risk Adjustment plans,
certain diagnosis codes are used as to determine severity of illness, risk, and resource
utilization. HCC impacts are often overlooked in the ICD-9-CM to ICD-10-CM conversion. The
physician should examine the patient each year and compliantly document the status of all
chronic and acute conditions. HCC codes are payment multipliers.

Summary of ICD-10-CM Impacts
Clinical Documentation
1. In diagnosing otitis media using ICD-9-CM you should document items such as acute,
chronic, not specified as acute or chronic, nonsuppurative or suppurative, and with or
without spontaneous rupture of the eardrum. In ICD-10-CM, you will need to document these
characteristics plus left, right or bilateral that are affected and is the problem initial or recurrent
to assign a correct code.
2. In this fictional test case we gave this young male a diagnosis of bipolar II disorder. You would
not report the bipolar disorder unless it affects treatment at today’s encounter. Conditions that
are not treated or that do not affect patient treatment nor are treated should not be reported.

Summary of ICD-10-CM Impacts
Clinical Documentation
1. In ICD-10-CM, gastro-esophageal reflux disease is differentiated by noting “with esophagitis”
versus “without esophagitis.” “With esophagitis” must be documented in the record.
Coding
Other Impacts
530.11 Reflux esophagitis is not coded when GERD is coded in ICD-9-CM because 530.11
is an “excluded code” from 530.81 in ICD-9-CM but it is a combination code in ICD-10-CM.

Scenario Details
Chief Complaint
• “I just got out of the hospital 2 days ago. I’m a little better, but still can barely breathe.”
History
67-year-old male with 40 pack/year history of cigarette use (still smoking) and severe oxygen
dependent COPD developed cough with increased production of green/gray sputum 2 weeks
prior to office visit. Admitted to hospital through Emergency Department with diagnosis of
presumed pneumonia superimposed on severe COPD. Hospital exam confirmed acute RLL
pneumococcal pneumonia. Patient treated with an IV cephalosporin as he has known penicillin
allergy, and was discharge from hospital to home 2 days prior to office visit.
PMH shows severe O2 dependent COPD, with type II diabetes mellitus secondary to chronic
prednisone therapy, which is treated with oral hypoglycemics. Patient also has known
hypertension, on ACE inhibitor therapy.
Review of Systems, Physical Exam, Laboratory Tests
T 99, BP 145/105, P 92 and irregular, RR 28
Chest exam shows decreased lung sounds throughout all lung fields except in RLL where there
were mild rhonchi and wheezes noted
ABG’s on 2L O2 by nasal cannula show PO2 62, PCO2 47, pH 7.40
CXR shows hyperinflation of lungs with small RLL alveolar infiltration. Comparison to CXR from
hospitalization shows approximately 75% resolution of pneumonia.
ECG reveals persistent atrial fibrillation which was not present on previous ECG of 6 months
earlier, but had been found at time of recent hospitalization. Labs show finger stick glucose
of 195mg%.
Assessment and Plan
Acute Community Acquired Pneumococcal Pneumonia: continue oral cephalosporin. Schedule
office follow up visit in 1 week with repeat CXR.
Severe COPD: continue O2, low dose Prednisone, and inhaled bronchodilator.
Chronic Hypoxemic, Hypercarbic Respiratory Failure
Persistent Atrial Fibrillation: continue digoxin initiated during recent hospitalization
Hypertension: continue ACE inhibitor therapy
Diabetes Mellitus, Type II, secondary to prednisone therapy; continue oral
hypoglycemic therapy

Summary of ICD-10-CM Impacts
Clinical Documentation
ICD-10-CM separates pneumonia by infectious agent. Document the infectious agent of pneu-
monia, as there are discrete ICD-10-CM codes for each type.
ICD-10-CM separates by acuity of respiratory failure, and hypoxia or hypercapnia, if present.
Document drug allergies with ICD-10-CM status” Z” codes from Chapter 21 to identify these.
Document the type of cardiac arrhythmia. Atrial fibrillation in ICD-10-CM separates into par-
oxysmal, persistent, chronic, typical, atypical, unspecified. Acute atrial fibrillation defaults to
unspecified in ICD-10-CM.
The Table of Drugs & Chemicals has a code assignment for Adverse effect of the drug that
would be followed by the secondary diabetes code. Go to the Volume 3 Index to Table of Drugs
and Chemicals. Along the left hand side proceed alphabetically to “Glucocorticoids” and then
move horizontally across to the column for Adverse Effect”. In Volume 1 (Tabular List) the in-
struction at the beginning of the code category T38 are the instructions for the 7th character.
Note: Drug-induced Diabetes Mellitus is a secondary type of diabetes due to the use of gluco-
corticoids. This code can only be coded as an “additional code” and would never be first-listed
The code categories for secondary diabetes are :
Due to underlying disease (E08)
Due to drug (E09)
Due to other specified condition such as post pancreatectomy. (E13)
These three categories can never be rst-listed per ICD-10-CM guidelines. The underlying cause
would be rst-listed diagnosis.

Coding
Other Impacts
Coding allergies to specific medications allows the providers who share a common EHR to be
notified of these allergies. They can be placed into the ongoing problem list therefore becoming
available whenever relevant for coding on the claim.
At the beginning of Chapter 10 Respiratory conditions this instruction is found:
Use additional code, where applicable, to identify:
exposure to environmental tobacco smoke (Z77.22)
exposure to tobacco smoke in the perinatal period (P96.81)
history of tobacco use (Z87.891)
occupational exposure to environmental tobacco smoke (Z57.31)
tobacco dependence (F17.-)
tobacco use (Z72.0)
These tobacco-related codes should also be coded into the ongoing problem list for future
coding situations as indicated in ICD-10-CM.

Other Impacts
E10.22 is a combination code in ICD-10-CM incorporating both the type of diabetes (type 1 is E10) and
the manifestation chronic kidney disease (after decimal point.22). Instructions from Volume 1 under the
code E10.22 is to “use additional code to identify stage of chronic kidney disease N18.1 –N18.6”. In
this documentation the ESRD is documented.
Code the type of diabetes and each associated complication (diabetes with renal disease and diabetic
neuropathy) in ICD-10-CM.
Code the stage of the patient’s chronic kidney disease per instruction under the diabetic code E10.22
Code the dialysis and AV graft by the use of “status codes” (Z codes). The key word to find this status
code in the Index to Diseases from Volume 3 is “Dependence” and then sub indent to the word “on”
and then to the words renal dialysis Z99.2

Her sugars however, have been poorly controlled with the Prednisone with fasting sugars
greater than 200.
Patient has long-standing asthma with 2-3 exacerbations per week and daily need for rescue
inhalers. Patient is still smoking half a pack a day. She is compliant with her inhalers when she
is not feeling well.
Patient has diabetes with overt proteinuria with her last creatinine of 1.3

Summary of ICD-10-CM Impacts
Clinical Documentation
Choosing the first-listed diagnosis in this scenario is determined by the Section IV Guidelines of
ICD-10-CM found in Volume 2 of ICD-10-CM
Section IV. Diagnostic Coding and Reporting Guidelines for Outpatient Services
Selection of first-listed condition
In the outpatient setting, the term first-listed diagnosis is used in lieu of principal diagnosis.
ICD-10-CM code for the diagnosis, condition, problem, or other reason for encounter/visit
List first the ICD-10-CM code for the diagnosis, condition, problem, or other reason for encoun-
ter/visit shown in the medical record to be chiefly responsible for the services provided. List ad-
ditional codes that describe any coexisting conditions. In some cases the first-listed diagnosis
may be a symptom when a diagnosis has not been established (confirmed) by the physician.
Asthma was chosen as first-listed in this scenario.
Asthma is classified as mild, moderate and severe with additional detail as intermittent, persis-
tent and severe; include if there is acute exacerbation or status asthmaticus. Bronchitis was not
specified as “acute” so the assignment is made to not specify as acute or chronic. In ICD-10-
CM both bronchitis and asthma are reported separately.
Bronchitis is reported separately from asthma per ICD-10-CM guidelines. Bronchitis was not
specified as acute or chronic and the default code would be J40. Conditions involving infec-
tious processes will have “acute” versus “chronic” choice. Providers should document when-
ever possible “acute” or “chronic”.
Guidelines require reporting of tobacco use or exposure for respiratory, vascular and some
other chronic illnesses such as oral and esophageal cancer codes. The guideline message for
using these codes is found at the beginning of the respiratory Chapter 10 in this scenario.
Diabetic manifestations are incorporated into the primary code for Diabetes Mellitus (combina-
tion codes). In this case diabetes with nephropathy is a combination code.
“Uncontrolled” diabetes is no longer a concept in ICD-10. Diabetes that is poorly controlled
should include whether hyperglycemia or hypoglycemia is present; whenever either is present
it should be coded accordingly. This patient would also have hyperglycemia reported as the
recorded Blood sugars show hyperglycemia.
Adverse effects of prescribed medications are reported from the Table of Drugs & Chemicals
and then a final code assignment from Tabular List for the 7th character. Identify which medi-
cations are causing adverse reactions and go to The Table of Drugs and Chemicals found in
Volume 3 of ICD-10-CM. Along the left side of that table find the drug or (drug class if individual
drug is not found.)
Then the 7th characters are found at the beginning of the T38 category in Volume 1 (Tabular
List) of ICD-10-CM. The choices for 7th character for this Table are:
A= initial encounter
D= subsequent encounter
S= Sequela

In this scenario it would be an initial encounter as this is the first time this provider is evaluating
the patient for this adverse effect.
Hypertension and Obesity are documented as co-morbid conditions and reported when treat-
ment is given for affected by these conditions. Instructions found at the obesity code instruct to
also report the BMI if documented.
