Purpose of this Workshop
To understand the differences
between the ICD-9 and ICD-10
guidelines and data elements,
and how to kick start your
transition by performing a gap
analysis of your current
documentation.
Part I - Course Objectives
• Understand the coding guideline
variations between ICD-9 and ICD-10
• Understand how to crosswalk your ICD9 codes using GEMs and other tools
• Understand the documentation impact
for ICD-10 by comparing documentation
elements between ICD-9 and ICD-10
Part II Course Objectives
• Know how to formulate a strategy for
conducting chart reviews
• Become comfortable evaluating
documentation for ICD-10 coding
• Develop strategies for implementing ICD10 documentation education
Regulatory Background
• 1996 – HIPAA - Regulations for privacy,
security, unique identifiers and electronic
transactions and code sets.
• 2000 – HHS final rule names standard
transactions to be used by covered entities
Covered entities are providers, payers and
clearinghouses who conduct specific
administrative transactions electronically
Regulatory Background, cont.
• January 16, 2009 HHS Final Rule
– Replace inflexible, ambiguous version 4010
electronic format with version 5010 with
mandatory use by January 1, 2012
– Adopt ICD-10 as the new code set to replace ICD9- CM with mandatory use by October 1, 2013
• August 24, 2012 HHS announces
October 1, 2013 deadline will be
pushed back to October 1, 2014
New Deadline:
Oct. 1, 2014
• Re-adjust your implementation
timelines
• This is not a time to relax, it is a time
to catch up
Kick Start Your Transition
• Awareness training for you and your
staff
• Familiarize yourself with the new
structure
• Documentation Improvement Program
– Perform gap analysis
– Provide feedback to providers
Overall Coding process is the same!

character codes to provide future expansion
• When a code has <6 characters and a 7th
character extension is needed – “x” is
assigned for all characters less than 7 to
meet the number of characters need to add
the 7th character extension

Classification Changes
Chapter 5 – Mental and Behavioral
Disorders
This chapter contains more subchapters,
categories, subcategories, and codes than
ID-9-CM. Consequently when comparing
ICD-10-CM to ICD-9-CM some disorders are
classified differently with greater clinical
detail.
Mental and Behavioral Disorders
• F10.10 – Alcohol abuse, uncomplicated
• F10.120 – Alcohol abuse with intoxication,
uncomplicated (305.00 – 305.03)
• F10.121 – Alcohol abuse with intoxication
delirium (291.0)
• F10.129 – Alcohol abuse with intoxication,
unspecified (305.00 – 305.03)
External Causes of Morbidity
• Formerly E-Codes, located in a
supplemental classification
• Capture the cause of the injury or health
condition, the intent, the place, activity,
and the person’s status (civilian or
military)
• V, W, X, Y codes in ICD-10
• More detailed than the E-Codes in ICD-9
W56.02XA Struck by a Dolphin,
Initial Encounter
W56.02XD Struck by a Dolphin,
Subsequent Encounter
W56.02XS Struck by a Dolphin,
Sequela with F32.8 Depressive
Episode
Coding Conventions
• Most coding conventions remain the
same
– Abbreviations
• NEC, NOS
– Punctuation
• ( ) Parentheses, : Colon, [] Bracket
– “Includes” instructional notes
New Features in ICD-10-CM
• Two types of exclusion notes:
– Excludes 1 – indicates not coded here - The
code excluded is never used with the code
– Excludes 2 – indicates not included here –
The excluded condition is not part of the
condition represented by the code and it is
acceptable to use both codes together if the
patient has both conditions
Changes to Coding Guidelines
for Timeframes
• Changes in timeframes specified in
certain codes
– Acute myocardial infarction – time period
for classification of “acute” changed from 8
weeks to 4 weeks
– Timeframe for abortion versus fetal death
changed from 22 weeks to 20 weeks
Mental, Behavioral and
Neurodevelopment disorders
• Selection of codes for “in remission” for
categories F10-F19 Mental and
behavioral disorders requires the
provider’s clinical judgment.
– The appropriate codes for “in remission”
are assigned only on the basis of provider
documentation
Psychoactive Substance Use,
Abuse And Dependence
• When the provider documentation refers to use, abuse
and dependence of the same substance, only one code
should be assigned to identify the pattern of use based
on the following hierarchy:
– If both use and abuse are documented, assign only the code
for abuse
– If both abuse and dependence are documented, assign only
the code for dependence
– If use, abuse and dependence are all documented, assign only
the code for dependence
– If both use and dependence are documented, assign only the
code for dependence.
Diseases of the Nervous System
• Document - Dominant/Non-dominant
in addition to Left or Right
• If dominant side is not documented use
the following default guidelines:
– For ambidextrous patients, the default should
be dominant.
– If the left side is affected, the default is nondominant.
– If the right side is affected, the default is
dominant.
Exposure to Tobacco Smoke
• Z77.22 Contact with and exposure to
environmental tobacco smoke
• P96.81 Exposure to tobacco smoke in
perinatal period
• Z57.31 Occupational exposure to
environmental tobacco smoke
Other Tobacco Use Codes

Part II - Chart Reviews
“A joint effort between the healthcare provider and
the coder is essential to achieve complete and
accurate documentation, code assignment, and
reporting of diagnoses and procedures.… The
importance of consistent, complete documentation
in the medical record cannot be overemphasized.
Without such documentation accurate coding cannot
be achieved.”

Practice Vignette – Pressure Ulcer
Patient is a 76 year old male who fell three weeks ago and fractured
his ankle. He is in poor health with steroid-induced diabetes due to
long term use for his Crohn’s Disease and ASHD. He is partially bedridden and has been in bed most of the past three weeks with his foot
elevated. For the past two of those three weeks, he’s had severe pain
in his heel. In addition, he hasn’t been eating well the past few days.
X-rays of the ankle revealed that the fracture fragments are in good
alignment; however, it was decided to replace the cast due to the
patient’s pain. When the cast was removed, a large decubitus ulcer of
the heel was found. The cast was replaced by a splint and the patient
was sent to PT for treatment of the ulcer.
Diagnoses: pressure ulcer of the heel, steroid induced diabetes, and
malnutrition. (Code only for the ulcer, diabetes and malnutrition)

Practice Vignette – Asthmatic Bronchitis
CHIEF COMPLAINT: This 5-year-old male presents to the practice with the
mother with "he has asthma." Mother states he has been wheezing and has
productive coughing. He has had some vomiting and some abdominal pain.
His peak flows the prior evening were normal at 150, but in the morning,
they were down to 100 and subsequently decreased to 75 over the course of
the day… day…Lives at home, here with the mother and there is no smoking
in the home.
MEDICAL DECISION MAKING: Chest x-ray reveals bronchial thickening,
otherwise no definite infiltrate. She received breathing treatments at home
and in the office and has continued tight wheezes with saturations 99%, but
sats are 92% with coughing spells. Based on the above, the hospitalist was
consulted and accepts this patient for admission to the hospital.
Diagnosis: Acute exacerbation of asthmatic bronchitis.

Practice Vignette – Asthma F/U
SUBJECTIVE: This is a 42-year-old white female who comes in today for a
follow up on asthma. She says her asthma has been worse over the last three
months. She has been using her inhaler daily. Her allergies seem to be a little
bit worse as well. Her husband has been hauling corn and this seems to
aggravate things. She has not been taking Allegra daily but when she does
take it, it seems to help somewhat. She has not been taking her Flonase which
has helped her in the past. She also notes that in the past she was on Advair
but she got some vaginal irritation with that.
ASSESSMENT/PLAN:
1. Intrinsic asthma. Seems to be worse than in the past. She is just using her
Proventil inhaler but is using it daily. We will add Flovent 44 mcg two puffs
p.o. b.i.d. May need to increase the dose. She is to call me if she is not
improving. We will plan on following up for reevaluation in one month.
2. Allergic rhinitis. We will plan on restarting Allegra and Flonase daily for the
time being.

Practice Vignette - Diabetes
Subjective: I am asked to see the patient today with ongoing
issues around her diabetic control. We have been fairly
aggressively, downwardly adjusting her insulins, both the Lantus
insulin, which we had been giving at night as well as her sliding
scale Humalog insulin prior to meals. Despite frequent decreases
in her insulin regimen, she continues to have somewhat low blood
glucoses, most notably in the morning when the glucoses have
been in the 70s despite decreasing her Lantus insulin from around
84 units down to 60 units, which is a considerable change. What I
cannot explain is why her glucoses have not really climbed at all
despite the decrease in insulin. The staff reports to me that her
appetite is good and that she is eating as well as ever.
