S27.1XXD is a billable diagnosis code used to specify a medical diagnosis of traumatic hemothorax, subsequent encounter. The code S27.1XXD is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code S27.1XXD might also be used to specify conditions or terms like traumatic hemothorax, traumatic hemothorax with open wound into thorax or traumatic hemothorax without open wound into thorax. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

S27.1XXD is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like traumatic hemothorax. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.

Information for Patients


Pleural Disorders

Your pleura is a large, thin sheet of tissue that wraps around the outside of your lungs and lines the inside of your chest cavity. Between the layers of the pleura is a very thin space. Normally it's filled with a small amount of fluid. The fluid helps the two layers of the pleura glide smoothly past each other as your lungs breathe air in and out.

Disorders of the pleura include

Many different conditions can cause pleural problems. Viral infection is the most common cause of pleurisy. The most common cause of pleural effusion is congestive heart failure. Lung diseases, like COPD, tuberculosis, and acute lung injury, cause pneumothorax. Injury to the chest is the most common cause of hemothorax. Treatment focuses on removing fluid, air, or blood from the pleural space, relieving symptoms, and treating the underlying condition.
