Congenital malformation of bony thorax, unspecified

This code signifies a birth defect affecting the skeletal structure of the chest, such as the ribs, sternum, or vertebrae, when the specific type of malformation is not documented. It indicates an abnormality present at birth that impacts the integrity or shape of the bony thorax.

Apply this code when medical record documentation confirms a congenital malformation of the bony thorax but lacks specific details regarding the exact nature of the defect (e.g., absent rib, fused sternum). This is appropriate when the physician has not specified a more precise diagnosis from the Q76 category.

• Avoid using this code if a more specific congenital malformation of the bony thorax (e.g., pectus excavatum, absent rib) is documented; always code to the highest level of specificity.
• Ensure documentation clearly states "congenital" to support the use of a Q-code.
• Review for any associated symptoms or conditions that may require additional coding, such as respiratory distress or scoliosis.
