The Y62–Y69 section covers misadventures to patients during surgical and medical care with 38 ICD-10-CM diagnosis codes, of which 33 are billable in fiscal year 2026. The section is organized into the 6 code ranges listed below.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- surgical and medical procedures as the cause of abnormal reaction of the patient, without mention of misadventure at the time of the procedure Y83 Y84
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the Y62–Y69 Code Range
ICD-10 codes Y62 through Y69 specifically address events where patients experience unintended harm during medical or surgical care. These codes are essential for documenting complications that happen because of medical interventions, not from underlying diseases.
These codes capture a range of issues that can occur during treatment, such as accidental medication errors, incorrect administration of medical devices, anesthesia-related problems, and surgical complications. Common terms for these events include "medical misadventure" or "iatrogenic injury," which correspond to this code section. Healthcare providers and coders use these codes to clearly identify when patient harm is linked to medical care, allowing for improved safety monitoring and quality control. Accurate use of the Y62-Y69 codes helps track patterns that might signal the need for changes in clinical practice to prevent avoidable harm.
