Subsequent Hospital/Observation code for high MDM?

• A. 99231
• B. 99232
• C. 99233
• D. 99234

Answer: (C)

Subsequent hospital or observation visits are rated by the level of Medical Decision Making (MDM), not by a fixed time alone. Among the subsequent care codes, higher MDM calls for a higher code. When the encounter involves high MDM, the appropriate code is the one that represents the most complex level, reflecting multiple problems being managed, substantial data reviewed, and higher patient risk. That makes the top option the correct choice for high MDM. Codes in this group map to levels of complexity: the lowest corresponds to straightforward MDM, the next to low-to-moderate, and the highest to high MDM. The highest level is used when the documentation supports high MDM, leading to more intensive management. The other codes in the range are for lower levels of MDM, so they fit fewer problems, less data review, or lower risk. Codes based on time or observation discharge (such as some observation-time-based codes) are separate, and aren’t the standard choice for a high-MDM, subsequent hospital/observation encounter. Therefore, for high MDM on a subsequent hospital/observation visit, the correct code is the highest level.
