ICD-10-CM S62.618K: Displaced fracture of proximal phalanx of other finger, subsequent encounter for fracture with nonunion

ICD-10-CM code S62.618K identifies a displaced fracture of the proximal phalanx of an other finger during a subsequent encounter for fracture with nonunion. Clinical literature notes that treatment for proximal phalanx fractures depends on displacement and orientation. This reference outlines the code definition and clinical context without providing personal medical advice. 3 6 2

Plain-language overview

Code S62.618K is titled displaced fracture of proximal phalanx of other finger, subsequent encounter for fracture with nonunion. This diagnosis code identifies a specific finger bone fracture evaluated during a follow-up encounter for nonunion. 3 6

What this code represents

The code S62.618K is listed among specific ICD-10-CM codes for displaced proximal phalanx fractures with subsequent encounter for nonunion, including S62.612K for the right middle finger and S62.617K for the left little finger. 6

Clinical context

Clinical literature establishes that treatment for fractures along the shaft of the proximal phalanx is dictated by the orientation of the fracture as well as the degree of initial displacement. 2

Nonoperative treatment is recommended for stable proximal phalanx fractures, and many stable phalanx fractures can be treated nonoperatively through close monitoring until clinical healing is noted. 1

Documentation considerations

The supplied coding sources provide the official label for S62.618K but do not explicitly list the specific documentation elements needed to support the use of this code. 3 6

What the sources add

The coding source S6 provides a categorical list of specific finger nonunion codes, while the clinical source S1 details various operative and nonoperative interventions for proximal phalanx fractures. 6 1

Clinical references S4 and S5 discuss the management of proximal phalanx fractures, whereas source S6 provides the specific ICD-10-CM code hierarchy for subsequent nonunion encounters. 4 5 6

Questions to verify

The supplied sources do not explicitly state whether documentation must specify which particular finger represents the other finger to accurately apply the S62.618K code. 3 6
