Code Description

ICD-10 E09.621 is a billable code used to indicate a diagnosis of drug or chemical induced diabetes mellitus with foot ulcer.

Key Diagnostic Point:

E09.621 refers to diabetes mellitus that has been induced by drugs or chemicals, specifically characterized by the presence of a foot ulcer. This condition arises when certain medications, such as corticosteroids or antipsychotics, lead to insulin resistance or impaired insulin secretion, resulting in elevated blood glucose levels. The foot ulcer is a significant complication of diabetes, often resulting from neuropathy, poor circulation, and impaired wound healing associated with hyperglycemia. Management of this condition requires careful monitoring of blood glucose levels, typically assessed through HbA1c testing, which reflects average blood glucose over the past two to three months. Treatment may involve insulin therapy, oral hypoglycemic agents, and wound care for the ulcer. The presence of a foot ulcer complicates the management of diabetes, as it increases the risk of infections and may necessitate surgical intervention. Therefore, comprehensive care is essential to address both the diabetes and the ulcer effectively.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between drug-induced diabetes and other types of diabetes
  • Documenting the specific drug or chemical responsible for the diabetes
  • Assessing the severity and stage of the foot ulcer
  • Understanding the interplay between diabetes management and ulcer treatment

Audit Risk Factors

  • Inadequate documentation of the drug or chemical causing diabetes
  • Failure to document the severity of the foot ulcer
  • Lack of clear treatment plans for both diabetes and ulcer
  • Inconsistent HbA1c levels not correlating with the diagnosis

Specialty Focus

Medical Specialties

Endocrinology

Documentation Requirements

Detailed medication history, HbA1c levels, and treatment plans

Common Clinical Scenarios

Patients presenting with new-onset diabetes due to medication, management of diabetes with concurrent foot ulcers

Billing Considerations

Endocrinologists must ensure clear documentation of the relationship between drug use and diabetes onset.

Podiatry

Documentation Requirements

Assessment of foot ulcer, treatment plans, and diabetes management

Common Clinical Scenarios

Patients with diabetic foot ulcers requiring surgical intervention or wound care

Billing Considerations

Podiatrists should document the impact of diabetes on wound healing and any referrals to endocrinology.

  • According to ICD
  • 10 guidelines, E09
  • 621 should be used when diabetes is specifically induced by drugs or chemicals and is accompanied by a foot ulcer
  • It is essential to document the specific drug involved and the characteristics of the ulcer

Exclusion Criteria

Do NOT use E09.621 When

Debridement of skin, subcutaneous tissue, and muscle

Clinical Scenario

Used for treating diabetic foot ulcers requiring extensive debridement.

Documentation Requirements

Document the extent of debridement and the condition of the ulcer.

Specialty Considerations

Podiatrists should ensure that the procedure is linked to the diabetic diagnosis.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of drug-induced diabetes, improving the accuracy of diabetes-related data and treatment plans. E09.621 provides a clear link between medication use and diabetes complications, which is essential for quality care and reimbursement.

ICD-9 vs ICD-10

Frequently Asked Questions

What types of drugs can induce diabetes mellitus?

Common drugs that can induce diabetes include corticosteroids, certain antipsychotics, and some antihypertensive medications. It is important to document the specific drug responsible for accurate coding.
