Reduction defects of upper limb (Q71)

The ICD-10 code Q71 covers various congenital reduction defects of the upper limb, which are conditions present at birth involving partial or complete absence of parts of the arm, forearm, hand, or fingers. These defects range from complete absence of one or both upper limbs to specific reductions such as absence of the radius, ulna, or hand, including distinctive forms like the lobster-claw hand.

This coding section is essential for identifying and documenting specific congenital anomalies of the upper extremities. For example, Q71.01 denotes the congenital complete absence of the right upper limb, while Q71.13 specifies bilateral absence of both upper arm and forearm with the hand present, also known as phocomelia. The code Q71.6 refers to "lobster-claw hand," a form of split hand malformation. The synonyms linked to these codes, such as "congenital absence of upper limb," "phocomelia," or "splitting hand," aid clinicians and coders in correctly matching clinical diagnoses with the right ICD-10 code. Using the precise codes from the Q71 category ensures accurate recording of complex congenital musculoskeletal conditions affecting upper limbs for treatment planning and tracking.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Choanal Atresia

A congenital abnormality that is characterized by a blocked CHOANAE, the opening between the nose and the NASOPHARYNX. Blockage can be unilateral or bilateral; bony or membranous.

Ectromelia

Gross hypo- or aplasia of one or more long bones of one or more limbs. The concept includes amelia, hemimelia, phocomelia, and sirenomelia.

Ectromelia virus

A species of ORTHOPOXVIRUS infecting mice and causing a disease that involves internal organs and produces characteristic skin lesions.

Ectromelia, Infectious

A viral infection of mice, causing edema and necrosis followed by limb loss.

Orthopoxvirus

A genus of the family POXVIRIDAE, subfamily CHORDOPOXVIRINAE, comprising many species infecting mammals. Viruses of this genus cause generalized infections and a rash in some hosts. The type species is VACCINIA VIRUS.
