What is the ICD-10 code for pituitary adenoma?

The ICD-10 code for a benign pituitary adenoma is D35.2. Use this code when histopathology confirms a benign neoplasm.

How do you code a functional pituitary adenoma?

For a functional pituitary adenoma, use D35.2 with additional codes for hormonal dysfunction, such as E22.8 for hyperprolactinemia.

Documentation & Coding Risks

Avoid these common issues when documenting Pituitary Adenoma.

Omitting secondary codes for hormonal dysfunction.

Impact

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

Mitigation

Review hormonal lab results., Ensure all relevant codes are used.

Using D35.2 without confirming adenoma histology.

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data on tumor prevalence.

Mitigation

Ensure histopathology report confirms adenoma before coding.

Histopathology documentation

Impact

Lack of histopathology confirmation for adenoma coding.

Mitigation

Require histopathology report before coding.
