The supplied sources list the code alongside other foot laceration codes and describe clinical complications of retained foreign bodies, but they do not explicitly define the sequela encounter character or guarantee payer coverage. 3 4 1

Plain-language overview

The official label for ICD-10-CM code S91.311S is laceration without foreign body, right foot, sequela. This code appears in a Medicare billing and coding article for wound and ulcer care. 3

What this code represents

Code S91.311S is listed in official Medicare articles alongside other foot laceration codes that specify left foot injuries and initial encounters, such as S91.312A and S91.312D. 3 4

The code S91.311S explicitly includes the phrase without foreign body in its official display label, distinguishing it from injuries where retained material is present. 3

Coding details

CMS articles list S91.311S separately from S91.312A, showing a structural distinction between right foot and left foot laceration codes within the same coding system. 3 4

Clinical context

Foreign bodies are often a complication of lacerations and other soft tissue injuries, and complications resulting from foreign bodies include inflammation, delayed healing, and damage to surrounding tissues. 1

An absolute indication for exploration and attempted removal of a foreign body is any patient presenting with neurovascular compromise or infection. 2

Documentation considerations

Imaging studies are necessary in cases of suspected but not identified foreign bodies, and the initial choice for foreign body detection is plain film radiography. 1

What the sources add

The CMS articles list S91.311S in the context of wound care billing, while the NCBI sources detail the clinical evaluation and complications of foreign bodies, adding different operational and clinical context to the code's meaning. 3 4 1 2

Coverage and utilization context

The appearance of code S91.311S in CMS billing and coding articles provides operational context for Medicare claims, but the supplied excerpts do not explicitly state that a code guarantees coverage by a specific payer. 3 4
