Range Overview
The ICD-10 code range T100-T108 covers complications of surgical and medical care that are not classified elsewhere. These codes are used to document injuries, poisoning, and other adverse effects resulting from medical or surgical procedures. The range includes codes for complications involving implanted devices, reactions to drugs, and post-procedural complications.
Key Usage Points:
- •Use these codes to document complications arising from medical or surgical care.
- •These codes cover a wide range of complications, including those involving implanted devices.
- •The codes also cover adverse reactions to drugs and other substances used in medical care.
- •Post-procedural complications are also included in this range.
- •Always code to the highest level of specificity.
Coding Guidelines
When to Use:
- ✓When a patient experiences a complication from a surgical procedure.
- ✓When a patient has an adverse reaction to a drug used in medical care.
- ✓When a patient has a complication involving an implanted device.
- ✓When a patient experiences a post-procedural complication.
When NOT to Use:
- ✗When the complication is covered by another specific code.
- ✗When the complication is a normal post-operative occurrence.
- ✗When the complication is due to patient non-compliance.
- ✗When the complication is due to a pre-existing condition.
Code Exclusions
Always verify exclusions with the latest ICD-10 coding manual.
Documentation Requirements
Documentation for codes in this range should include a detailed description of the complication, the medical or surgical procedure that led to the complication, and any treatment provided for the complication.
Clinical Information:
- •Description of the complication
- •Medical or surgical procedure that led to the complication
- •Treatment provided for the complication
- •Outcome of the complication
Supporting Evidence:
- •Operative report
- •Medical record notes
- •Laboratory results
- •Imaging results
Good Documentation Example:
Patient experienced an adverse reaction to the anesthesia used during a surgical procedure. The reaction was treated with antihistamines and the patient recovered without further complications.
Poor Documentation Example:
Patient had a reaction to surgery.
Common Documentation Errors:
- ⚠Not coding to the highest level of specificity
- ⚠Not documenting the medical or surgical procedure that led to the complication
- ⚠Not documenting the treatment provided for the complication
Range Statistics
Coding Complexity
The complexity of coding in this range is medium due to the need to accurately identify the specific complication and the medical or surgical procedure that led to the complication. Additionally, coders must navigate the numerous subcategories within this code range and code to the highest level of specificity.
Key Factors:
- ▸Determining the specific complication
- ▸Identifying the medical or surgical procedure that led to the complication
- ▸Coding to the highest level of specificity
- ▸Navigating the numerous subcategories within this code range
Specialty Focus
These codes are used across a variety of medical specialties, including surgery, anesthesiology, and internal medicine.
Primary Specialties:
Clinical Scenarios:
- • A patient experiences a post-operative wound infection after a surgical procedure.
- • A patient has an adverse reaction to a drug used during a medical procedure.
- • A patient experiences a complication involving an implanted pacemaker.
- • A patient has a post-procedural complication after a surgical procedure.

Frequently Asked Questions
Can I use these codes for complications that are normal post-operative occurrences?
No, these codes should not be used for normal post-operative occurrences. They should only be used for complications that are not expected as part of the normal post-operative recovery process.
