ICD-10-CM Code T70.29
Other effects of high altitude
Non-Billable Code
Non-Billable means the code is not sufficient justification for admission to an acute care hospital when used a principal diagnosis. Use a child code to capture more detail.7th Character Required
Code requires 7th Character Extension identifier. This 7th Character usually captures Episode of Care information, such as "Initial Encounter," "Subsquent Encounter," or "Sequela."ICD Code T70.29 is a non-billable code. To code a diagnosis of this type, you must use specify a 7th character that describes the diagnosis 'other effects of high altitude' in more detail. The 7th characters that can be added, and the resulting billable codes, are as follows:
| 7th Digit | Billable Code | 7th Digit Specifies |
|---|---|---|
| A | T70.29XA | initial encounter |
| D | T70.29XD | subsequent encounter |
| S | T70.29XS | sequela |
What is 7th Character Extension?
For codes less than 6 characters that require a 7th character a placeholder 'X' should be assigned for all characters less than 6. The 7th character must always be the 7th position of a code. E.g. The ICD-10-CM code T67.4 (Heat exhaustion due to salt depletion) requires an Episode of Care identifier. T67.4XXA Initial Encounter or T67.4XXD Subsequent Encounter. More InfoThe ICD code T702 is used to code High-altitude pulmonary edema
High-altitude pulmonary edema (HAPE) (HAPO spelled oedema in British English) is a life-threatening form of non-cardiogenic pulmonary edema (fluid accumulation in the lungs) that occurs in otherwise healthy mountaineers at altitudes typically above 2,500 meters (8,200 ft). However, cases have also been reported at lower altitudes (between 1,500–2,500 metres or 4,900–8,200 feet in highly vulnerable subjects), though what makes some people susceptible to HAPE is currently unknown. HAPE remains the major cause of death related to high-altitude exposure, with a high mortality rate in the absence of adequate emergency treatment.
