S52.599Q is a billable ICD-10 code used to specify a medical diagnosis of other fractures of lower end of unspecified radius, subsequent encounter for open fracture type i or ii with malunion. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
S52.599Q is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like other fractures of lower end of unspecified radius for open fracture type i or ii with malunion. 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.
Unspecified diagnosis codes like S52.599Q are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Greenstick fracture of distal radius
- Skillern's fracture
