Debridement of an abrasion such as “road rash” most likely would be coded as 11040 or 11041, depending on whether it's a partial-or full-thickness abrasion. Note that these codes would include application of any topical anesthetic before the debridement.

Not specifically. Your best bet is 781.9 (other symptoms involving nervous and musculoskeletal systems).

Yes. The codes' descriptions may not be the most clear that CPT has to offer, but your interpretation is correct.

Use codes 99341-99350 to report evaluation and management (E/M) services “provided in a private residence.” Like other E/M services, the proper level of service for a home visit depends on the levels of the history and examination as well as the complexity of the medical decision making that the visit involves. Note that there are separate home-visit codes for new patients (99341-99345) and established patients (99347-99350).

The best choice probably would be one of the “office or other outpatient services” codes (99201-99215). People tend to think of these codes as officevisit codes only. However, according to CPT, you may use these codes to report E/M services provided “in an outpatient or other ambulatory facility.” An adult day-care center would seem to fit this description.

No. According to CPT, the newborn-care codes (99431–99435) are for “normal newborn” care. For services provided to an infant in the hospital, use the E/M codes for initial (99221–99223) and subsequent (99231–99233) hospital care.

No. CPT indicates that when a patient is admitted to a nursing facility during the course of an encounter in another setting (e.g., hospital observation care) on the same date, you should submit only the code for the nursing facility admission. An exception to this rule is hospital discharge (99238-99239) or observation discharge (99217) services performed on the same date as a nursing facility admission. These services may be reported separately.

Try code 99080, “Special reports such as insurance forms, more than the information conveyed in the usual medical communications or standard reporting form.”
