Which chapter of ICD-10-CM contains codes for neoplasms?
Answer: Chapter 2 (C00–D49)
Chapter 2 of ICD-10-CM (codes C00–D49) covers all neoplasms, including malignant, benign, in situ, and neoplasms of uncertain behavior.
When coding a sequela (late effect) condition in ICD-10-CM, what is the correct sequencing?
Answer: Sequence the nature of the sequela first, followed by the sequela cause code
For sequela coding, the residual condition (nature of the sequela) is sequenced first, followed by the sequela code identifying the original cause, with limited exceptions.
When a patient has both an acute and a chronic form of the same condition, how should ICD-10-CM codes be sequenced?
Answer: Code both, sequencing the acute condition first
Per ICD-10-CM guidelines, when both acute and chronic forms exist, both are coded with the acute (subacute) condition sequenced first.
What does the etiology/manifestation convention require in ICD-10-CM?
Answer: Two codes are required: the underlying disease first, followed by the manifestation code
The etiology/manifestation convention requires two codes, with the underlying disease (etiology) sequenced first and the manifestation code listed second; manifestation codes cannot be principal diagnoses.
For outpatient coding, how should a diagnosis documented as 'possible' or 'probable' be coded?
Answer: Code the signs, symptoms, or other definitive reason for the visit instead
For outpatient encounters, uncertain diagnoses ('possible,' 'probable,' 'suspected') must NOT be coded as confirmed; instead, code the documented signs, symptoms, or other definitive findings.
