Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

About the W44 Code Range

The ICD-10 code W44 covers instances where a foreign body enters or passes through a natural orifice of the body. These codes specify the type of object involved, including batteries, plastics, metals, organic materials, and sharp objects, and differentiate the clinical encounter as initial, subsequent, or sequela.

This section is used to classify injuries or medical conditions caused by objects like batteries, including button batteries; plastic objects such as beads, toys, or jewelry; various types of glass; magnetic metal and non-magnetic metal objects; and organic materials like food or insects entering or passing through natural body openings. The category also covers other non-organic and sharp objects such as needles or knives. For example, the ICD-10 code W44.9XXA, which includes terms like "foreign body in right ear" or "foreign body in auditory canal," helps identify unspecified foreign bodies entering natural orifices. These detailed categories aid healthcare providers and coders in accurately capturing the nature and timing of the injury or complication related to foreign bodies in orifices.

Questions About This Page

How many billable codes are in the W44 range?

Of the 177 codes in this range, 126 are billable and valid for claim submission from October 1, 2025 through September 30, 2026. Category header codes group them but cannot be reported on claims.

What does the W44 range classify?

The range classifies foreign body entering into or through a natural orifice. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
