Code Description

ICD-10 E11.621 is a billable code used to indicate a diagnosis of type 2 diabetes mellitus with foot ulcer.

Key Diagnostic Point:

Type 2 diabetes mellitus is a chronic condition characterized by insulin resistance and relative insulin deficiency. It is often associated with various complications, including neuropathy, nephropathy, retinopathy, and cardiovascular diseases. One of the significant complications of diabetes is the development of foot ulcers, which can arise due to poor circulation, neuropathy, and impaired wound healing. Foot ulcers in diabetic patients can lead to severe infections, gangrene, and even amputations if not managed properly. The presence of a foot ulcer indicates a need for comprehensive management, including glycemic control, regular foot examinations, and appropriate wound care. The management of diabetes involves monitoring HbA1c levels, which reflect average blood glucose levels over the past two to three months. An HbA1c level of 7% or lower is generally recommended for most adults with diabetes to reduce the risk of complications. Insulin therapy may be required for some patients, particularly those who cannot achieve adequate glycemic control with oral medications alone. Proper documentation of the patient's diabetes management, including HbA1c levels and the status of foot ulcers, is crucial for accurate coding and reimbursement.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for detailed documentation of diabetes management and complications
  • Variability in foot ulcer severity and treatment approaches
  • Potential for multiple co-existing conditions complicating the coding
  • Requirement for accurate HbA1c level documentation

Audit Risk Factors

  • Inadequate documentation of foot ulcer severity
  • Failure to document HbA1c levels
  • Lack of evidence for diabetes management plans
  • Inconsistent coding of related complications
