Valid for Submission
S00.449D is a billable diagnosis code used to specify a medical diagnosis of external constriction of unspecified ear, subsequent encounter. The code S00.449D is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 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.
S00.449D is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like external constriction of unspecified ear. 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 S00.449D 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 appropriate 7th character is to be added to each code from block Superficial injury of head (S00). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Information for Patients
A bruise is a mark on your skin caused by blood trapped under the surface. It happens when an injury crushes small blood vessels but does not break the skin. Those vessels break open and leak blood under the skin.
Bruises are often painful and swollen. You can get skin, muscle and bone bruises. Bone bruises are the most serious.
It can take months for a bruise to fade, but most last about two weeks. They start off a reddish color, and then turn bluish-purple and greenish-yellow before returning to normal. To reduce bruising, ice the injured area and elevate it above your heart. See your health care provider if you seem to bruise for no reason, or if the bruise appears to be infected.
