S23 is the authoritative medical code for Dislocation and sprain of joints and ligaments of thorax. This classification is used in medical billing and clinical recording to specify the clinical criteria for dislocation and sprain of joints and ligaments of thorax (ICD-10-CM S23), ensuring healthcare documentation aligns with current federal coding standards.
Billing Status: NO. This is a clinician non-billable / parent hierarchy grouping in the ICD-10-CM system.
Official Registry Overview & Definition
Dislocation and sprain of joints and ligaments of thorax is a non-billable ICD-10-CM category code S23. A more specific billable subcode must be selected for claims submission. Includes: avulsion of joint or ligament of thorax; laceration of cartilage, joint or ligament of thorax; sprain of cartilage, joint or ligament of thorax; traumatic hemarthrosis of joint or ligament of thorax; traumatic rupture of joint or ligament of thorax; traumatic subluxation of joint or ligament of thorax; traumatic tear of joint or ligament of thorax; injuries of breast; injuries of chest wall; injuries of interscapular area. Excludes2 (not included here): dislocation, sprain of sternoclavicular joint (S43.2, S43.6); strain of muscle or tendon of thorax S29.01-; burns and corrosions T20-T32; effects of foreign body in bronchus T17.5; effects of foreign body in esophagus T18.1; effects of foreign body in lung T17.8; effects of foreign body in trachea T17.4; frostbite T33-T34; injuries of axilla; injuries of clavicle; injuries of scapular region; injuries of shoulder; insect bite or sting, venomous T63.4. Code also: any associated open wound. 7th character: The appropriate 7th character is to be added to each code from category S23.

Frequently Asked Questions (FAQ) & Clinical Guidance
Can S23 be billed directly?
No. S23 (Dislocation and sprain of joints and ligaments of thorax) is a non-billable ICD-10-CM category code. A more specific billable subcode must be selected based on clinical documentation.
Does S23 require a 7th character?
Yes. The appropriate 7th character is to be added to each code from category S23; A: initial encounter; D: subsequent encounter; S: sequela.
Can S23 be reported alongside related conditions?
Per official ICD-10-CM Excludes2 instructions, S23 and the following are not considered part of each other and may both be reported when both conditions are present: dislocation, sprain of sternoclavicular joint (S43.2, S43.6); strain of muscle or tendon of thorax (S29.01-); burns and corrosions (T20-T32); effects of foreign body in bronchus (T17.5).
