T22.149S Burn of first degree of unspecified axilla, sequela

ICD-10-CM Code T22.149S: Burn of first degree of unspecified axilla, sequela

ICD-10-CM code T22.149S identifies a sequela of a first-degree burn located in the unspecified axilla. The concept is classified as an injury or poisoning diagnosis. It is designated as a billable code, meaning it may be used on claims to specify a medical diagnosis for record-keeping purposes. The supplied sources establish its semantic type and billing status. 3 5

Plain-language overview

Code T22.149S is named as a burn of first degree of unspecified axilla, sequela, and it is classified under the semantic type of injury or poisoning. This provides the official label and concept classification for this specific diagnosis. 3

What this code represents

The designation T22.149S is identified as a billable code, which permits its use to specify a medical diagnosis on claims. This billable status distinguishes it from non-billable codes like T22.15, which cannot be used directly for such specification. 5

Documentation considerations

Code T22.149S is listed alongside distinct codes for the right axilla, T22.141S, and the left axilla, T22.142S. This listing in the source document demonstrates the existence of laterality-specific codes that correspond to the unspecified axilla code. 4

What the sources add

The semantic concept details from the EVS Explore source provide the official naming and classification, while the Codigo source adds the operational detail regarding its billable status. Together, these sources establish both the conceptual identity and the billing utility of the code. 3 5

The Labcorp document includes T22.149S within a list of various first-degree burn sequela codes, whereas the Codigo source explicitly defines the billable specificity of T22.149S. This comparison shows a difference between a code's inclusion in an administrative list and its explicit billing designation. 4 5

Clinical context

The literature includes a reference to post-burn axillary contracture as a therapeutic challenge. This establishes that burns in the axillary region are discussed in clinical literature regarding management and outcome. 2

A review of burn classifications notes that the combination of historical classifications determines the degree of burn injury. This provides background on how burn depth degrees, such as first degree, are conceptually derived in the literature. 1
