M3505 - Drug-induced muscle weakness affecting the shoulder area

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code indicates muscle weakness in the shoulder region that has been caused by medications or drugs. This condition occurs when certain medications interfere with normal muscle function, leading to weakness, fatigue, or reduced strength in the shoulder muscles. The weakness may affect your ability to lift your arms, carry objects, or perform daily activities involving shoulder movement. This is typically a side effect of medication rather than a primary muscle disease, and symptoms may improve when the causative medication is adjusted or discontinued under medical supervision.

Additional Information

The underlying cause is medication-related, so treatment typically focuses on identifying and managing the causative drug while monitoring for improvement in muscle function. Recovery time varies depending on the specific medication and individual patient factors.
