Range Overview

high priority

The ICD-10 category T110-T118 is dedicated to capturing complications of surgical and medical care that are not classified elsewhere. This range includes complications related to drugs, biological substances, and other medical and surgical procedures. The codes within this range are used to document complications that have occurred during or after medical or surgical care, which are not attributed to the condition for which the treatment was performed.

Key Usage Points:

  • These codes are used when a complication arises from medical or surgical care, but does not fit into other specific complication categories.
  • The codes within this range are not used to document the underlying condition for which the treatment was performed.
  • The specific type of complication, such as infection, hemorrhage, or other complication, should be documented.
  • The timing of the complication, whether during or after the procedure, should be documented.
  • The specific procedure or treatment that led to the complication should be documented.

Coding Guidelines

When to Use:

  • When a patient develops a postoperative infection that is not classified elsewhere.
  • When a patient experiences a hemorrhage during a surgical procedure that is not classified elsewhere.
  • When a patient has an adverse reaction to a drug or biological substance used during medical care.
  • When a patient experiences a complication from a medical device used during treatment.
  • When a patient has a complication from a surgical procedure not classified elsewhere.

When NOT to Use:

  • When the complication is specifically classified in another category.
  • When the complication is a routine surgical risk or expected outcome.
  • When the complication is due to the patient's underlying condition, not the treatment.
  • When the complication occurs outside the context of medical or surgical care.
  • When the complication is due to patient noncompliance or self-inflicted.

Code Exclusions

Always verify exclusions by cross-referencing the specific code in question with the ICD-10 manual.

Documentation Requirements

Documentation for this code range should clearly state the type of complication, the specific procedure or treatment that led to the complication, and the timing of the complication. The documentation should also indicate that the complication is not attributable to the patient's underlying condition.

Clinical Information:

  • Type of complication
  • Specific procedure or treatment
  • Timing of complication
  • Confirmation that complication is not due to underlying condition
  • Any relevant clinical findings or test results

Supporting Evidence:

  • Operative reports
  • Medical record notes
  • Laboratory or imaging results
  • Medication administration records
Good Documentation Example:

Patient developed a postoperative infection following a knee replacement surgery. The infection is not related to the patient's underlying osteoarthritis. Culture results confirmed the presence of Staphylococcus aureus.

Poor Documentation Example:

Patient has an infection.

Common Documentation Errors:

  • Not specifying the type of complication
  • Not linking the complication to a specific procedure or treatment
  • Not documenting the timing of the complication
  • Attributing the complication to the patient's underlying condition

Coding Complexity

Medium
Complexity Rating

The complexity of coding for this range is considered medium due to the need to accurately determine the cause of the complication, identify the specific procedure or treatment, and understand the timing of the complication. Additionally, there are numerous exclusions to navigate, and the codes within this range are frequently updated.

Key Factors:
  • Determining whether the complication is due to the treatment or the underlying condition
  • Identifying the specific procedure or treatment that led to the complication
  • Understanding the timing of the complication
  • Navigating the various exclusions for this code range
  • Keeping up-to-date with changes and updates to this code range

Specialty Focus

This code range is particularly relevant to specialties that frequently perform surgical procedures or administer medical treatments, such as general surgery, orthopedics, and anesthesiology.

Primary Specialties:
General Surgery
30%
Orthopedics
25%
Anesthesiology

Clinical Scenarios:
  • A patient develops a postoperative infection following a hernia repair surgery.
  • A patient experiences a hemorrhage during a hip replacement surgery.
  • A patient has an adverse reaction to a medication administered during a colonoscopy.
  • A patient experiences a complication from a pacemaker implanted to treat atrial fibrillation.
  • A patient has a complication from a laparoscopic cholecystectomy not classified elsewhere.

Frequently Asked Questions

Can I use a code from this range if the complication is due to the patient's underlying condition?

No, these codes are only used to document complications that are due to the medical or surgical treatment, not the patient's underlying condition.
