What does the 7th character D in S46.011D mean?

The final character D marks a subsequent encounter: use it for routine care while the strain of muscle(s) and tendon(s) of the rotator cuff of right shoulder is healing, after active treatment has ended.

Under the General Equivalence Mappings, strain of muscle(s) and tendon(s) of the rotator cuff of right shoulder, subsequent encounter converts to ICD-9-CM V58.89 (other specfied aftercare). The mapping is approximate, so confirm the match fits the documentation.

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.
