Muscle weakness (generalized)

This code signifies a pervasive reduction in muscle strength affecting multiple muscle groups throughout the body, not localized to a specific area or limb. It indicates a generalized debility or lack of physical power.

Apply this code when documentation explicitly states "generalized muscle weakness" without a more specific underlying cause or location. This is appropriate for conditions like post-viral fatigue, general deconditioning, or as a symptom of systemic illness when a more precise diagnosis for the weakness isn't yet established.

• Do not use this code if the weakness is localized to a specific limb or muscle group; instead, look for more specific codes (e.g., hemiparesis, monoplegia).
• Always sequence this code after the underlying condition causing the generalized weakness, if known.
• Remember the Excludes1 note: never code this alongside M62.84 for muscle weakness specifically due to sarcopenia.
