Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the P94 range.

Transient Neonatal Myasthenia Gravis

A condition characterized as a temporary autoimmune neuromuscular disease leading to fluctuating muscle weakness and fatigue in a newborn infant.

About the P94 Code Range

These conditions affect a newborn’s muscle tone, or how tight or loose the muscles feel.

The subdivisions separate transient neonatal myasthenia gravis (P94.0) from high muscle tone present from birth (P94.1) and low muscle tone present from birth (P94.2). Other newborn muscle tone disorders fall under P94.8; P94.9 leaves the disorder unspecified.
