Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to Y90: its own notes plus those printed at block Y90-Y99 and Chapter 20. A note printed at a category, block or chapter applies to every code under it.

Code First

The underlying condition named in the note is sequenced before this code.

  • any associated alcohol related disorders (F10)

Notes

General instructions on how these codes are used.

From Block Y90-Y99 Supplementary factors related to causes of morbidity classified elsewhere applies to 334 codes
  • These categories may be used to provide supplementary information concerning causes of morbidity. They are not to be used for single-condition coding.
From Chapter 20 (V00-Y99) External causes of morbidity and mortality applies to 7,461 codes
  • This chapter permits the classification of environmental events and circumstances as the cause of injury, and other adverse effects. Where a code from this section is applicable, it is intended that it shall be used secondary to a code from another chapter of the Classification indicating the nature of the condition. Most often, the condition will be classifiable to Chapter 19, Injury, poisoning and certain other consequences of external causes (S00-T88). Other conditions that may be stated to be due to external causes are classified in Chapters I to XVIII. For these conditions, codes from Chapter 20 should be used to provide additional information as to the cause of the condition.
