Wrist Strain ICD-10-CM Codes

What are Wrist Strain ICD-10-CM Codes?

Wrist strain refers to injury involving the stretching or tearing of the wrist's muscles or tendons, often in the radiocarpal joint or carpal joint. Accurate coding is critical for documenting the initial encounter, subsequent encounter, or sequela.

Common ICD-10-CM Codes for wrist strain are as follows:

• S63.501A – Unspecified sprain of right wrist, initial encounter: Use this when a patient has a new sprain affecting the right wrist. This includes pain in the carpal joint of the right wrist or ligament damage.
• S63.501D – Unspecified sprain of right wrist, subsequent encounter: Used for follow-up visits.
• S63.501S – Unspecified sprain of right wrist, sequela: This indicates chronic issues following a sprain or strain.
• S63.502A – Unspecified sprain of left wrist, initial encounter: This indicates an injury to the flexor muscles of the left wrist.
• S63.502D – Unspecified sprain of left wrist, subsequent encounter
• S63.502S – Unspecified sprain of left wrist, sequela

Which wrist strain ICD codes are billable?

Yes, all six codes—S63.501A, S63.501D, S63.501S, S63.502A, S63.502D, and S63.502S—are billable and support reimbursement for documented treatment and symptoms.

Clinical information

A wrist strain involves the stretching or tearing of muscles or tendons in the wrist joint. It’s closely related to a sprain, which affects ligaments.

• Causes include sudden impacts, overuse, improper lifting, or repetitive stress on the carpal joint.
• Symptoms may include localized pain, swelling, reduced motion, and tenderness in either the right or left wrist joint.
• Standard treatment often includes RICE (Rest, Ice, Compression, Elevation), pain relief medications, and wrist splints.
• The diagnosis should focus on ruling out fractures and assessing tendon or ligament involvement for unspecified sprain or unspecified wrist injuries.
• Physical therapy may help restore function and prevent future strain, especially in athletes or individuals with repetitive wrist activity.
• Severe or untreated strains can lead to chronic instability, joint degeneration, or complications requiring surgical repair.
• Accurate documentation of whether the injury is to the right wrist, left wrist, or unspecified wrist is essential for selecting the appropriate code, such as:
  • Unspecified sprain of left wrist
  • Unspecified sprain of right wrist
  • Sprain of unspecified wrist
• Sprain of carpal joint may also be used when ligament damage is localized specifically to that area.

Synonyms include

• Wrist muscle strain
• Flexor muscle injury
• Torn wrist tendon
• Right wrist sprain
• Sprain of right wrist
• Left wrist sprain
• Sprain of left wrist
