Asphyxiation due to systemic oxygen deficiency due to low oxygen content in ambient air due to unspecified cause
Not billableICD-10-CM diagnosis code.
This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.
Submit one of these 3 more specific codes instead:
- T71.20XA Asphyxiation due to systemic oxygen deficiency due to low oxygen content in ambient air due to unspecified cause, initial encounter
- T71.20XD Asphyxiation due to systemic oxygen deficiency due to low oxygen content in ambient air due to unspecified cause, subsequent encounter
- T71.20XS Asphyxiation due to systemic oxygen deficiency due to low oxygen content in ambient air due to unspecified cause, sequela
This code requires a seventh character. See the rule below.
What has happened to this code
Every change the publisher made, from 2014 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.
- FY2014 Added to the draft code set draft Asphyxiation due to systemic oxygen deficiency due to low oxygen content in ambient air due to unspecified cause
Official coding rules
Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
