Code Also Notes in Chapter 10: Diseases of the respiratory system ICD-10-CM
A Code Also note means two codes may be needed to fully describe a condition; it gives no sequencing direction. In Chapter 10 (J00-J99), notes printed in the chapter name other codes 42 times, and Code Also Notes anywhere in the Tabular List name the chapter’s codes 62 times, covering 32 distinct codes, categories and ranges.

Questions About Code Also Notes
What does a Code Also note mean?
A Code Also note instructs that two codes may be required to fully describe a condition, but it does not give sequencing direction (Section I.A.17). The FY 2027 Tabular List has 689 of them; 495 name other codes, with 538 references to 349 distinct codes, categories and ranges.
Which code goes first with a Code Also note?
The note does not decide it. Sequencing depends on the circumstances of the encounter: normally the condition that is the main reason for the visit goes first.
