T70.8XXD is a billable diagnosis code used to specify a medical diagnosis of other effects of air pressure and water pressure, subsequent encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
T70.8XXD 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 effects of air pressure and water pressure. 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.

- A - initial encounter
- D - subsequent encounter
- S - sequela
Present on Admission (POA)
T70.8XXD is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.
CMS POA Indicator Options and Definitions
| POA Indicator | Reason for Code | CMS will pay the CC/MCC DRG? |
|---|---|---|
| Y | Diagnosis was present at time of inpatient admission. | YES |
| N | Diagnosis was not present at time of inpatient admission. | NO |
| U | Documentation insufficient to determine if the condition was present at the time of inpatient admission. | NO |
| W | Clinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission. | YES |
| 1 | Unreported/Not used - Exempt from POA reporting. | NO |

Patient Education
Barotrauma
Barotrauma means injury to your body because of changes in barometric (air) or water pressure. One common type happens to your ear. A change in altitude may cause your ears to hurt. This can happen if you are flying in an airplane, driving in the mountains, or scuba diving. Divers can also get decompression sickness, which affects the whole body.
Common symptoms of ear barotrauma include:
- Pain
- A feeling that your ears are stuffed
- Hearing loss
- Dizziness
Treatments for ear barotrauma include chewing gum and yawning to relieve the pressure. Medications such as decongestants may also help.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
