Failure in dosage during surgical and medical care (Y63) ICD-10-CM
The Y63 code range covers failure in dosage during surgical and medical care with 10 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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 Y63 Code Range
The ICD-10 code Y63 series identifies various types of dosage failures occurring during surgical and medical care. These codes are essential for documenting specific incidents such as giving too much or too little of a fluid, radiation, or medication, helping ensure precise clinical and billing records.
Codes like Y63.0 cover errors such as an excessive amount of blood or fluids given during transfusions or infusions, while Y63.1 refers to incorrect fluid dilution during infusion. Radiation treatment errors are categorized under Y63.2 for overdoses and Y63.3 for inadvertent patient exposure. Treatment dosage errors in therapies like electroshock or insulin-shock appear under Y63.4. Local application issues, such as inappropriate temperature during packing, use Y63.5. Underdosing or failure to administer necessary drugs falls under Y63.6. Broader dosage failures in surgical and medical care, including excessive doses of vaccines or biological substances, are captured by Y63.8. When the specific nature of the dosage failure is unclear, Y63.9 is applied, which includes errors like wrong dose of medication or prescription mistakes. These codes serve medical coding teams and healthcare professionals in accurately identifying and reporting dosage-related complications.
