ICD-10-CM S82.891J: Other fracture of right lower leg, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing

ICD-10-CM code S82.891J identifies a subsequent encounter for an other fracture of the right lower leg, specifically for an open fracture type IIIA, IIIB, or IIIC with delayed healing. Open lower limb fractures carry risks of delayed union. This code is listed in CMS billing articles, and clinical literature details the severity of type III open fractures. 3 5 2 1

Plain-language overview

Code S82.891J represents a subsequent encounter for another fracture of the right lower leg, specifically for an open fracture type IIIA, IIIB, or IIIC with delayed healing. This code is listed in a CMS billing article and an ICD-10-CM code tree. 3 5

What this code represents

The code S82.891J is listed alongside other right lower leg fracture codes that distinguish between initial and subsequent encounters, open and closed fractures, and healing outcomes like routine healing, delayed healing, nonunion, and malunion. 5

Clinical context

Open fractures of the lower limb have a greater risk of delayed union compared to closed fractures. Type III open fractures involve significant soft tissue damage, wound contamination, and fracture instability, making them difficult injuries to classify and treat. 2 1

The classification for type III open fractures is based on wound severity, size, periosteal stripping, contamination, and vascularity. Type III injuries have undergone modifications to allow a more accurate prognosis for these severe injuries. 1

Documentation considerations

The code S82.891J specifies a subsequent encounter for an open fracture type IIIA, IIIB, or IIIC with delayed healing. The ICD-10-CM code tree lists distinct codes for routine healing, delayed healing, nonunion, and malunion for these open fracture types. 5

Coverage and utilization context

The code S82.891J appears in a CMS billing and coding article for major joint replacement. The listing of this code in a CMS article provides operational context, but the supplied excerpts do not establish specific payer coverage rules. 3

What the sources add

The CMS article lists the code S82.891J with its description, while the ICD-10-CM code tree source lists S82.891J alongside related codes that differentiate healing outcomes and encounter types for right lower leg fractures. 3 5

Clinical literature from PMC establishes that open lower limb fractures carry a risk of delayed union, while another PMC article details the injury patterns and classification criteria for type III open fractures. 2 1
