What does an 'Excludes1' note in ICD-10-CM mean?
Answer: The two conditions cannot occur together and cannot be coded simultaneously
An Excludes1 note means the two conditions are mutually exclusive and cannot be reported together on the same claim.
In ICD-10-CM, what is the purpose of a 7th character 'S' (sequela)?
Answer: Indicates complications or conditions that arise as a direct result of a previous injury or illness
The 7th character 'S' identifies sequela, which are late effects or residual conditions resulting from a previous injury or illness.
Which ICD-10-CM instruction requires the underlying condition to be coded first, followed by the manifestation?
Answer: Code first
A 'Code first' note instructs the coder to sequence the underlying etiology before the manifestation code.
What does the placeholder character 'X' serve in ICD-10-CM codes?
Answer: Fills an empty character position to allow a future 7th character to be added
The placeholder X is used to fill character positions that have no assigned value so a required 7th character can be added.
According to ICD-10-CM guidelines, how should an uncertain diagnosis be handled in the inpatient setting?
Answer: Code the condition as if confirmed
For inpatient encounters, ICD-10-CM guidelines allow coding a condition described as 'probable,' 'suspected,' or 'possible' as if established.
What is the correct sequencing when coding a condition with both an acute and chronic presentation in ICD-10-CM?
Answer: Code the acute condition first, followed by the chronic condition
When both acute and chronic forms of the same condition exist, the acute (subacute) code is sequenced first.
