2025 Unspecified ICD-10-CM Codes - Page 3
The 2025 Unspecified ICD-10-CM Codes list includes 29,292 valid codes for situations where medical documentation does not provide enough detail to assign a more specific code. While coders are encouraged to use the most detailed diagnosis possible, unspecified codes are sometimes necessary to accurately reflect the patient’s condition when clinical information is incomplete. Proper use of these codes helps reduce claim denials, supports accurate billing, and ensures compliance with Medicare and payer guidelines. Documentation must clearly support the need for using an unspecified code.
