Primary ICD-10-CM Code for acromegaly

Acromegaly and pituitary gigantism
Billable Code

Decision Criteria

clinical Criteria

  • Presence of pituitary adenoma and elevated IGF-1

Applicable To

  • Acromegaly
  • Pituitary gigantism

Excludes

  • Gigantism due to other causes

Clinical Validation Requirements

  • Elevated IGF-1 levels >1.3x ULN
  • GH levels ≥1 ng/mL during OGTT
  • MRI showing pituitary adenoma

Code-Specific Risks

  • Misclassification with gigantism
  • Omitting comorbid conditions

Coding Notes

  • Ensure all comorbid conditions are documented and coded.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Benign neoplasm of pituitary gland

D35.2
Use when imaging confirms pituitary adenoma.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Carcinoid syndrome

E34.0
Requires negative 5-HIAA urine test to exclude.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Acromegaly to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E22.0.

Impact

Clinical: Incomplete clinical picture, Regulatory: Potential audit risk, Financial: Missed reimbursement opportunities

Mitigation Strategy

Review patient history for comorbidities, Ensure all relevant conditions are coded

Impact

Reimbursement: Incorrect DRG assignment, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation

Mitigation Strategy

Always sequence E22.0 before comorbid conditions.

Impact

Incorrect sequencing of primary and secondary codes.

Mitigation Strategy

Regular training on ICD-10 guidelines.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Endocrinology progress note

Specialty: Endocrinology

Required Elements

  • Subjective symptoms
  • Objective lab results
  • Imaging findings
  • Assessment and plan

Example Documentation

SUBJECTIVE: 'Worsening jaw protrusion, new sleep apnea.' OBJECTIVE: IGF-1: 450 ng/mL, MRI: 12mm pituitary adenoma.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Elevated GH levels
Good Documentation Example
GH nadir 2.4 ng/mL during OGTT
Explanation
Specifying the exact GH level provides clear clinical validation.
