Question

question 18

an established 47-year-old patient presents to the providers office after falling last night in her apartment when she slipped on water on the kitchen floor. she is complaining of low back pain and no tingling or numbness. provider documents that she has full range motion of the spine, with discomfort. her gait is within normal limits. straight leg raising is negative. she requested no prescription medication. it is recommended to use heat, such as a hot water bottle. take ibuprofen as needed for pain. providers assessment: lower back muscle strain. what e/m and icd-10-cm codes are reported for this service?

99213, s33.9xxa, w18.40xd, y92.030
99212, s39.012a, w18.30xa, y92.030
99213, s39.012a, w01.0xxa, y92.030
99212, s39.012a, w19.xxxd, y92.030

Explanation:

Determine the correct E/M code

The patient is established, seen in the office, with a minor problem (low back muscle strain, self-care with heat and OTC Ibuprofen, normal gait, negative straight leg raise). This represents a straightforward level of medical decision-making (MDM) or a low-level visit, corresponding to CPT code 99212 (established patient, straightforward MDM) rather than 99213 (low MDM).

Determine the primary diagnosis code

The provider's assessment is "Lower Back Muscle Strain".

• \(S39.012A\) represents strain of muscle, fascia and tendon of lower back, initial encounter.
• \(S33.9XXA\) represents sprain of unspecified parts of lumbar spine and pelvis, initial encounter.

Since the diagnosis is explicitly a muscle strain, \(S39.012A\) is the correct primary diagnosis code.

Determine the external cause codes

The patient slipped on water on the kitchen floor of her apartment.

• \(W01.0XXA\) represents fall on same level due to slipping, tripping and stumbling without mention of liquid or object (not matching "slipped on water").
• \(W18.30XA\) represents fall on same level, unspecified, initial encounter (too generic).
• \(W19.XXXD\) represents unspecified fall, subsequent encounter (incorrect encounter seventh character).
• \(W18.40XD\) represents slipping, tripping and stumbling without falling, subsequent encounter.
• Looking at the options, the combination of 99212, \(S39.012A\), \(W18.30XA\), and \(Y92.030\) (kitchen of single-family private house/apartment as the place of occurrence) is the only clinically and logically consistent choice matching the 99212 level of service and the strain diagnosis.

Answer:

• (A) 99213, S33.9XXA, W18.40XD, Y92.030
• (B) 99212, S39.012A, W18.30XA, Y92.030 (Correct answer)
• (C) 99213, S39.012A, W01.0XXA, Y92.030
• (D) 99212, S39.012A, W19.XXXD, Y92.030
