Deficiencies of neck and trunk

This code signifies congenital absence or significant underdevelopment of structures in the neck or trunk. This includes conditions like agenesis or hypoplasia of vertebrae, ribs, or other skeletal components within these regions. It represents a birth defect affecting the structural integrity of the axial skeleton from the neck down to the pelvis, excluding limb deficiencies.

Use this code for patients diagnosed with congenital malformations characterized by missing or severely underdeveloped bones or soft tissues of the neck and torso. This applies to conditions identified at birth or during early childhood that specifically involve a deficiency in these anatomical areas. It is appropriate when the primary issue is the absence or severe hypoplasia of a body part in the specified region.

• Ensure the documentation clearly specifies a deficiency (agenesis, hypoplasia) rather than a deformity or other type of malformation.
• Verify that the affected anatomical site is definitively within the neck or trunk, excluding extremities.
• Consider additional codes to specify the exact nature of the deficiency or any associated conditions, if known.
