The ICD-10 Spotlight: Know the codes feature that appeared throughout Partners 
in Health Update last year was designed to communicate various coding 
conventions, general guidelines, and chapter-specific guidelines in ICD-10. 
These conventions and guidelines are rules and instructions that must be 
followed to classify and assign the most appropriate code. As with ICD-9, 
adherence to these guidelines is required under the Health Insurance 
Portability and Accountability Act (HIPAA).
As announced in the January 2013 edition of Partners in Health Update, we have 
introduced a new feature called Putting ICD-10 into Practice: Coding exercises 
and scenarios. Each month this feature will help you put the new guidelines and 
conventions you learned about last year into practice. If needed, use the 
ICD-10 Spotlight: Know the codes booklet for assistance with these exercises. 
An answer key is provided below so you can verify if your answers are correct. 
In addition, a list of code narratives is included to describe each ICD-10 code.
Coding exercises
Code the following conditions according to ICD-10 coding conventions and 
guidelines:
Borderline glaucoma
Congestive heart failure due to hypertension
HIV positive status without symptom
Urinary frequency
Morbid obesity with a BMI of 42 in an adult
Congenital red cell aplastic anemia
Cleft palate involving both the soft and hard palate with bilateral cleft lip
Severe persistent asthma with acute exacerbation
Fatigue fracture of vertebra, lumbar region, and subsequent encounter for 
fracture with delayed healing
Interstitial cystitis due to E. coli with hematuria
Sleep-related teeth grinding
Non-conclusive HIV-test finding in infants
Coding scenario
Code the following scenario according to ICD-10 coding conventions and 
guidelines: 
Jane and John Doe were shopping at the mall the day after Thanksgiving to take 
advantage of the sales. While rushing for the newest iPhone, John fell down the 
stairs. Thankfully, John sustained only minor abrasions to his right elbow.
