CRC ICD-10-CM Diagnosis Coding 3

Question 1

A patient with Hb-SS sickle cell disease presents with acute chest syndrome and pain crisis. What is the correct coding?

Accepted Answer

D57.01 for acute chest syndrome, which encompasses the crisis state

Answer

D57.01 specifically identifies acute chest syndrome in Hb-SS disease, which inherently indicates a crisis state.

Question 2

A provider documents 'paraplegia secondary to old T12 spinal cord injury' from 8 years ago. How should this be coded?

Accepted Answer

G82.20 and S34.109S for both current condition and cause

Answer

Both the current functional deficit (G82.20) and the sequela code for the cause should be coded. Paraplegia maps to HCC 70.

Question 3

A patient has atrial fibrillation and sick sinus syndrome with tachycardia-bradycardia. How are these coded?

Accepted Answer

I48.91 and I49.5 separately

Answer

These are distinct arrhythmia conditions without an Excludes1 note between them. Both may coexist independently.

Question 4

A patient has 'chronic pain syndrome' and 'chronic pain due to left hip osteoarthritis.' How should the coder proceed?

Accepted Answer

Code G89.4 and M16.12, with the underlying condition first

Answer

Per ICD-10-CM guidelines, when chronic pain syndrome coexists with an identified cause, both should be coded with the underlying condition sequenced first.

Question 5

A provider documents 'patient has controlled HIV on antiretroviral therapy with undetectable viral load.' What code is assigned?

Accepted Answer

B20 Human immunodeficiency virus disease

Answer

B20 is correct. Once diagnosed with HIV disease, B20 is assigned for all subsequent encounters regardless of viral load status.
